*UPDATE 3* PS1 compression tips: remove dead space beforehand

UPDATE 3 PS1 compression tips: remove dead space beforehand

Compressed and playable?

Garrett sent us a rather informative email about playing PS1 games on your PSP. He seems to have found a way to make the games run without all the extra padding originally placed on the disc. If you're wondering what that means, it's this: Imagine playing a 500MB game using only 50 MB of space.

You'll need something called CDGenPS2, which we've placed for download below. If you follow the steps, you should be able to get a game to play with a drastically smaller file size. We're currently testing it, but you're free to try out the procedure, too. Garrett says he'll make a more in-depth tutorial on it if people run into problems, which is really nice of him. For now, you'll do well to read through his email below (with some slight changes for grammar and clarity).

PS1 and PS2 games use a very strict architecture for how the binary files of the games are organized on a discs. When a disc copying program copies these discs, it's known that they will leave the padding of empty bits (0xFF) for the remainder of the XXXMB media.

For example, Tetris Plus for the PS1 has a total file size on the disc of 43.0 MB and the image from CloneCD is 566MB. However, if you try to remove the padding from a disc, it will no longer work with emulators, including POPS. A utility for those who load games from their PS2 hard drives to lessen the size of the images, known as CDGENPS2 (Much like UMD-GEN), has the ability to remove this padding and keep the structure of the disc intact. Using this utility with some software that can extract an ISO to its contents can bring the 566MB Tetris Plus image down to about 50MB (POPS compresses it to about 400MB).

How to do it:

Extract the ISO contents to a folder on your hard drive.
Open that folder and select ALL of the extracted contents from the root of the disc.
Open CDGENPS2.
Drag the contents of the folder into the CDGENPS2 window (the giant white space that says ISO near the top)
(Optional) Go to file-> Edit Volume and change the name of the volume so that it matches the original title of the game (for archival reasons only).
Click the IMG button on the left-hand side of the screen and save the Bin/ISO/IMG to whatever directory you want , and use POPS to convert to PSP EBOOT and test it.

If it doesn't work and I get enough emails about it not working I will write a more in-depth tutorial about it with screenshots and everything on the forums.

UPDATE 1:

We tested it and the process seems to be working fine. Our test used R-Type Delta as the subject.

Normal file size: 323 MB
Using the usual compression methods: around 234 MB
Using Garrett's method: around 191 MB

As you can see, that seems pretty good. Your mileage will vary depending on the type of game you picked up and how much of the space in the disc is just dummy data. While you might say "Duh," we just felt the need to check. Right now, we're all pretty excited to see how drastic some changes wil be. Expect some data-filled games (like RPGs) to still remain big, as there's less dummy space that gets taken out.

UPDATE 2:

Due to insistent public demand (or frustration...both apply), Garrett (or Zero-X) has posted a graphical walkthrough of sorts for his compression tips. He's also using a program called ISOBuster for his procedure, so we've opted to add it as a download.

Note, however, that your mileage will still vary. Not every game will work on PopStation, and the amount of space saved by procedure will differ depending on the game and the content involved. Zero-X has a couple of comments on the forum link which should explain that a bit more.

UPDATE 3:

Garrett added an additional note that we noticed just now on the comments. It seems the LBA arrangement will have a big impact on whether or not the game you're tweaking will actually run.

For the sake of clarity, we're going to post two additional comments made by Garrett and Devilgun that should fix most of your problems. If not, then there may be something else getting in the way of getting your games to work properly.

Garrett's comment:

You can do so with ISOBuster by exporting a Tree File, and then using CDGENPS2's advanced menu to import it (this is a new discovery to me too, as none of my LBA's were changed thru drag + drop).

Also, you can fix them manually by comparing the LBA section from whatever ISO utility you are using with the LBA in CDGENPS2. Starting from the top, compare the LBA and change it accordingly by: right-clicking the file, and clicking propeties. Check the FIX LBA box type in the correct LBA value.

Devilgun's comment happens to explain the manual fix by having many exclamation points. We took notice of that, and Garrett did too, as he confirms Devilgun's comment. Here's his step-by-step guide, though you'll need MagicISO for it:

Open the iso/bin with MagicISO
Now you can see the data AND the !!!LBA!!! Information
Copy the Data to a new Folder on Harddisk or just drag and drop it to CDGENPS2
!!!!!NOW!!!!! LOOK AT THE LBA Information in CDGENPS2. IT has to be the SAME for each File as in MagicISO - So order the files, so that the LBA is exactly the same.
Make the IMG
Compress it with pops.
Play it!

# Nice..... — Guest 2007-01-12 17:06

Damn this is def a great find. I hope things go well in testing this concept. Ill try my hands at it & will let know if success. If failure i'll shamefully keep to my self... hehe.

# where to get eboots — Guest 2007-01-12 17:07

do you want chocolate chip cookies? *Say yes!*

# Wow. — Guest 2007-01-12 17:09

I really want to see how this turns out. I'm going to wait a little longer to see reports on how it is done and how the games are affected on the PSP. If all's well I could theoretically get my entire PS1 library onto my 4GB memstick (currently only holding 5 games among a bunch of other things).

# Ugh.... — Guest 2007-01-12 17:10

Blah, now i have to revert my .eboots back to isos, rip them and turn them back into eboots >< I hope the compiling for the isos doesnt take as long considering the files are only 50mbs each after....

# does it work for 3.01? — Guest 2007-01-12 17:12

or only for 3.02B?

# ? — Guest 2007-01-12 17:15

Wow. Are you for real? I'm checking out your forum and wow it seems you really are giving out PS1 Games for PSP. Yeah...I'm downloading one of them now...I really hope this isn't a trick.

BTW: I'm pretty sure your posting a link to a site for free ISOs is illegal and definately against website policy.

# it works for 302b — Guest 2007-01-12 17:17

it works for 302b

# hmm — Guest 2007-01-12 17:17

so.... this is like compression but not acually compressing, similar to the dummy file theroy

# Fantastic development — DrNicket 2007-01-12 17:21

This is a great day for POPStation users! I'll cross my fingers and give it a try a little later tonight. I'll post my results somewhere.

Thanks for the heads up Garrett!

# Unable to rar — Guest 2007-01-12 17:25

if only winrar could extract the PS ISOs in the first place...

# this needs to be incorporated. — Illegal Machine 2007-01-12 17:46

to one of those GUI programs that people have been putting out.

I personally couldnt figure it out... but this needs to be in the Popstation mix for sure!

# Eww.. — Guest 2007-01-12 17:47

That's exactly why I save the ISOs on my computer, even when i'm done with them.

# Results not typical — Guest 2007-01-12 17:50

A Suikoden 2 ISO of 513 MB with lvl 9 popstation compression = 347MB

A Suikoden 2 ISO after this procedure = 436MB with a lvl 9 popstation compression to a 265MB eboot. However, the game doesn't want to load.

Good compression, but definitely not the 50MB goal. And no game play. I think the results of this compression method definitely depend on the game. Somehow I doubt FFVII will even shrink that far.

# I'm gonna test it — Guest 2007-01-12 17:51

I'm gonna test it, I'll post my results later.

# FF7 CD1 — Guest 2007-01-12 17:53

I just did FF7 CD1

With CDGenPS2 PSXPSP game was 403MB

Without CDGenPS2 game was 529MB

Both are final PSXPSP games using 9 compression.

However, the CDGenPS2 game did not work. I either did something wrong or not all games work.

# best site of isos — Guest 2007-01-12 17:55

# Does Not Work — Guest 2007-01-12 18:00

Well, I followed the above instruction and guess what? it does not work. I used FF7 and the file size still big (622mb) The one compressed by popstation, by contrast, is only (529mb). very disappointed. sigh

Whenever I try to remove the dead space of an ISO it becomes 37.0 kbs! I know that this can't be right because I put in FF VII Disc 1. Plus whenever I try to save it saves it in the .ps2 format. HELP PLEASE!

# Extract? — McSesameChicken 2007-01-12 18:06

How do you extract the ISO contents? I'm assuming they don't just mean the .iso file, because I tried using this program with that, and nothing at all was compressed (Final Fantasy Tactics, if anyone's interested).

# ughhhhh — Guest 2007-01-12 18:07

Did you not listen!?!? Suikoden WILL NOT be a 50mb game! theres simply too much data!!!!!!! compare suikoden to tetris! jesus, get a grip.

In your 3rd paragraph you *sort of* redeem yourself by actually realizing that it depends on the game, but i cant believe you actually expected a 50mb suikoden

# sd — Guest 2007-01-12 18:12

It was a ton smaller for me, but the game did not work.

# Extracting — Guest 2007-01-12 18:13

Use an archiving program... I suggest WinRAR. Once you download winrar then double click the iso files and extract them to where you want them to go.

# BIN FILES! — Guest 2007-01-12 18:16

When I extract the ISO from my eboots I only get BIN Files so i can't open them and take the files contents out! Anyone know how I can convert it?

# How abt mixed mode PSX images? — Guest 2007-01-12 18:16

I am assuming that this should work ideal for normal PSX games which have no audio tracks. But using a software like ultraiso to extract the image will only preserve the data and not the audio tracks.. :(

# didn't work for me as well — peeInMyPantz 2007-01-12 18:17

I tried the same thing with FF7 CD1, got the same file size, but it doesn't work as well. Just give me a blank black screen after the warning page

# thank you for the benefit of the doubt. — Guest 2007-01-12 18:17

I posted before the update which talked about the size differences. I was clarifying for those who were peeing their pants over 50mb isos. Thank you for attacking me with harsh words. I definitely feel like this is a community I want to participate in more often.

# What now? — McSesameChicken 2007-01-12 18:21

I used WinRAR to try to open up my FFT.iso file, but it says that no archives were found within the selected files or folders. What now?

# for converting bin's you could use — Guest 2007-01-12 18:29

"MagicISO" or "Daemon Tools"

# Thanks — Guest 2007-01-12 18:39

I used Magic ISO and got all the needed files... I am converting it right now.

Tried it out with Crash Team Racing.

Followed the instruction.

No compression.

Didnt load.

# Sigh...didnt work — Guest 2007-01-12 18:57

I tried extracting bin files instead of iso and then convert them to eboots. So far didnt work for me...

Is this only for isos?

Failed: extract bin, make new iso, compress to eboot

Testing: bin to iso, make new iso, compress to eboot

# may not be the fault of the process — Guest 2007-01-12 19:06

I tried to rerip the files from the .img using a diff method and noticed that two folders couldnt be copied because of I/O errors.

Also had the same problem with bushido blade 2.

So the ctr i made was missing files so thats definitely why it didnt work.

# Same — Guest 2007-01-12 19:16

Tried Megaman X5 possibly my favorite PSX game.

Dragged files straight from the CD to CDgen, got an IMG that was 600+ megs.

My compressed Eboot is 355.

A little depressing.

# rebuilt isos not workin with epsxe — Guest 2007-01-12 19:19

The two isos ive rebuilt using magiciso to extract the files from the disc image have failed to work with epsxe

Ridge Racer R4

my assumption is if they dont work with the emulator they wont work as eboots

# FFVII — Guest 2007-01-12 19:22

i tried FFVII...RESULTS 750MB------->734MB ...yay..

# I meant — Guest 2007-01-12 19:22

Meant to say the other compressed Eboot was smaller than this one made by CDgen.

# about 100 more — Guest 2007-01-12 19:24

i tried compressing gran turismo 2 and ( about 600 mb)

and i got 700 mb :| thats odd.

# LOL — Guest 2007-01-12 19:25

I tested Blazing Dragons with it and ended up with a larger image than when I started.

ISO = 287 mb

After cdgenps2v2 = 322 mb

# Improvement is improvement — Kichigai 2007-01-12 19:28

While this isn't compression, per se, it does assist in creating a smaller compressed file, thus the title is accurate (so stop complaining). Just wondering if anyone has yet to produce a working POPStation image yet? So far, I've just seen a bunch of marginal improvements (10-20%, but it's still an improvement, and I'm not complaining) with nothing that works being produced.

# . — Guest 2007-01-12 19:30

Yeah, not sure if he forgot to mention a step in the instructions, or if this just has a really low success rate. Because so far it just seems to make a much smaller eboot that gives you a nice pretty black screen.

# Didn't work — Guest 2007-01-12 19:30

I started off with Final Fantasy Tactics... Here is what I did step by step.

1. Ripped the BIN file from my previous eboot.

2. Converted it to ISO

3. Compressed it using CDGENPS2

4. Using POPSTATION made an eboot compressed at level nine.

File Sizes:

Original: 529 Mb

Compressed: 200Mb!

The only problem is that after the Gameboot the game won't load. Anyone else having this problem?

# . — Guest 2007-01-12 19:31

Very likely because you saved the new image as a bin file. Save it as an ISO next time.

# Strange — Guest 2007-01-12 19:32

I tried Final Fantasy Tactics which is normally 250mb compressed.

After this procedure it came down to 200mb.

It didn't work however, but strangely the PSX emu recognized the game as the old one and still had the same settings- other than that, it hung on a black screen.

# Good In theroy — Guest 2007-01-12 19:35

Sounds GREAT .... but from the above posts ... it doesn't work real well ?!?!?!

How about fixing it so it works and combining it with a "pop station" GUI???

# This new is great But!! — RomTheStampede 2007-01-12 19:41

# hmn — Guest 2007-01-12 19:43

I got Capcom Vs Snk Pro down to 114megs with this plus popstation compression...but it wont load. what gives?

(also, later when I retried converting the files into bin instead of iso, I got 78 megs....but still no loading!!)

# someone tried use isobuster? — Guest 2007-01-12 20:13

this program can man match original file structure, to do more compatible eboot.

the method work with ps2 games

this is only a theory, dont blame me if dont work

# Ive tried with many games, were all doing something wrong wait... — Guest 2007-01-12 20:41

lets wait for that picture tut hes gonna put up soon

# ... — Guest 2007-01-12 21:15

If it works on any games and saves me valuable MSspace, than it IS worth trying. Thanks for sharing the discovery .

# it might just be.. — Guest 2007-01-12 21:17

For those of you using the the cdgen method, make sure you are keeping the disc structure in tact. I havent tried this with POPS yet, but i know it definately is an issue when reconstucting ISO for use in my PS2. Also, I see most of you guys that have tried FFVII have tried compression lvl 9. I know you want the most saved space possible, but have you tried a different compression level? It may just be that the somthing isnt written write during compression. I suggest starting from level 1 and going up and see how far you can go before it stops working. I will try myself when i get my psp back from my friend (drinks + 4am = bad memory)

# Rain in Spain? — Guest 2007-01-12 21:26

# . — Guest 2007-01-12 21:35

It won't matter what compression level they use.

The rebuilt iso won't even work in a PSX emu, so it obviously isn't going to work as an eboot either.

# tryed what songoku119 said — Guest 2007-01-12 21:38

tryed FFvii with no comprestion it sill didn't work

# This is stupid. — Guest 2007-01-12 21:39

It requires you to extract the files, this causes all RAW data to be lost. Most of the games reported not working is because is this, RAW data is lost.

Also, compression makes the padding useless - try making a 10MB text file, full of spaces, and compress it in ZIP - you get a ~10KB file - this is the same for padding, compression reduces padding to almost nothing.

Totally useless IMO - unless you MUST use 3.02 OE-B and don't need RAW data (which most games do).

# Does this really work? — Guest 2007-01-12 22:21

i have tried nearly all the games i own with this compression process and my success rate is 0. i have done everything possible to make it work. I even tried R-Type Delta, which was supposed to be your test subject. It does, yes, reduce the size of most games (except for harvest moon, it adds about 3 megs) but it leaves us with an unfortunate downside of little or no enjoyment of the game itself. The compression is a great find, but we need to work it until it is perfected.

# its not a compression — Guest 2007-01-12 22:40

i wonder how often it has to be repeated, so i shout it:

THIS IS NOT A COMPRESSION!!!

you take parts of the iso out of it. the result is a still uncompressed iso. you must compare the sizes after compression then.

but the problem is:

IT DOES NOT WORK FOR ME.

all games i tried it on, from crash bandicoot 1-3 to gran turismo ... about 20 of them... did result in a blank screen.

even if i use the lba-extraction method (not mentioned in the article but used before to modify ps2 isos by me) it still resulted in a black screen.

thus i will be waiting for a tutorial on some other game... not the mentioned ones. i would propose the guide to include crash bandicoot 3, as this game also contains defective sectors and some illegal filenames (with . at the end) ;-)

anyways, i wonder if this will get any huge results in many games. if the dummy data on the cd has patterns, then the compression algorythm should also mostly get rid of the dummy data (repeating data normally is compressed rather good. if not then we need to do something about the compression algorythm).

# Doesn't work — Guest 2007-01-13 01:29

I did the same with Gran Turismo 2.

The eboot is just under 400MB but doesn't load.

# Try being observant — Guest 2007-01-13 01:31

CDgenPS2 allows you to save it as an iso.

# lmao @ shroud — Guest 2007-01-13 01:35

lolol

# shame it doesn't boot — Guest 2007-01-13 01:37

Pretty useless tool if the games don't load.

# Doesn't work — Guest 2007-01-13 01:40

Doesn't work Eboot.

# No changes — Guest 2007-01-13 01:49

I tried three games included R-Type delta that as reported as working and shrinkable.

After following the steps i obtaiened from CDGENPS2 a BI/CUE that in size is exactly as the original ISO. So after popstationed it the result is that the PBP has the same size.

The same with other three game (All with DUMMY file inside) and if I regenerate the ISO including the DUMMY file obiouvsly the output iso doesn't change in terms of size, due I selected all files from souce ISO.

I think that something is missing in the tips. I think that the dummy file need to be removed, and do some actions to make the ISO working after removed DUMMY.

But I tried some test, fixing LBA or filling the DUMMY with a mor comprimable pattern, but the games still not working.

Bye

# Final Fantasy 9 — Guest 2007-01-13 02:29

tried the compression- blows. Started with 706mb, after compression ended up with 830 mb file with failure to load. total waste of time.

# dont compress — Guest 2007-01-13 02:40

From the sounds of it, you shouldnt be compressing the games after you have removed the dummy files. Just rip it out and use popstation with no compression, just to make the eboot. That should solve the not working problem.

From the sound of it, you can't have dual compression, so to speak. Just one or the other.

# FFVIII — Guest 2007-01-13 03:09

I tried the method with FF8, and once i have put it through the entire process, the iso has been shrunken, but when i use Popstation converter, it's the same size, as the on where i didn't use cdgen!?

Using psx2psp u can convert eboots back to iso's

# damnit — Guest 2007-01-13 03:58

yeai. tested resident evil directors cut and die hard trilogy, both get blank screen after gameboot.

followed the instructions in this way:

1. dragging image into virtual drive in alcohol 52

2. placed all files to cdgenps2

3. made new iso

4. pushed iso into popstation gui 221 and finally made the eboot.

black screen.

# Black frozen screen after warning screen — Guest 2007-01-13 04:13

Dumped contents of ISO (resident evil -directors cut) using ISObuster, used CDGENPS2 to remove spaces and then created an EBOOT using level 9 compression.

No good.

Crashes after wanring screen.

# bin to iso converter???!!! — Guest 2007-01-13 04:15

I've been trying to see how this works and I see that if you convert a bin image file to a iso file, using magiciso, you also get a "shrinkage" unfortunately you also get the same black screen!!!

I think the only reason it get smaller is because the bin file contains extra information like music tracks. Doesn’t seem like this is program is removing any dummy files but rather removing the subdata….

There might have been a step left out of the tutorial, but I don't believe it. I think this was an untested tip sent in.

I think you'll find that talking like you know s-hit when you don't is gonna get you flamed, rtard.

This is for any ps1/ps2 image and maybe some similar platform compressions.

# there's a reason it won't work — comedy 2007-01-13 10:41

the iso thing has information in it... that extra 'dummy' data you're deleting isn't all dummy data.

maybe tetris plus worked but it sounds like a lazily made game, a game which is bigger and more complex probably uses the valuable data in the iso thingy itself... i wouldn't try this as i've often come across this kind of thing when trying to back up games before now.

and what's the point if it'll only save 20 megs here or there?

go buy a 2 gig mem card, they're cheap as dirt now (and i'm in the uk! - about 40 quid somewhere), then you can get almost 3 games onto one stick... you can get 3 with the proper compression thing in popstation.

# Sorry for confusion — Guest 2007-01-13 11:02

Allright, I made a mistake in my directions, my exact method skips the extraction to hard disk. I simply drag ISO contents from MagicISO and drop them into CDGENPS2, if you want my Eboot for tetris (minus the aduio tracks as well) e-mail me, and i can send you the *WORKING EBOOT* to prove it works. I have written a graphical tutorial which can be seen here:

http://forums.qj.net/f-general-psp-help-22/t-guide-shrinking-psx-game-size-89945/page2.html#post1322239

Sorry for the confusion and the adding of an extra step (I did it to avoid other confusion, but it seems that that causes the method to stop working)

And to those saying that compression nearly nullifies zero-space, you are correct MOST compression algorithms do, however the POPS compression algorithm does not, try it with tetris plus: 566 MB ISO -> about a 400MB EBOOT with compression lvl 9 however using my method and removing the CDDA audio (which is about 40MB of the disc) I have about an 8mb eboot with keys.bin and it works.

# ! — Guest 2007-01-13 11:03

I have read a few post that say they compressed the iso with cdgenps2v2! Ok ok lets get it straight (popstation eboots are compressed), but cdgen does not compress the original iso you are just building one but without the dummy files. The main problem is that most of u(not all) are taking out files that are important to the game so therefore it will not run. And by the way ME, qj should not take down resources because some fairly ignorant person doesnt know how to work them. God i wish there was a program to EXTRACT idiots from life Please developers of cdgen get to working on one. I usually dont disrespect people but ask questions before posting IT DOESNT WORK.

# Common... — Guest 2007-01-13 11:52

...Guys...

1. Open the iso/bin with MagicISO

2. Now you can see the data AND the !!!LBA!!! Information

4. Copy the Data to a new Folder on Harddisk or just drag and drop it to CDGENPS2

5. !!!!!NOW!!!!! LOOK AT THE LBA Information in CDGENPS2

IT has to be the SAME for each File as in MagicISO

- So order the files, so that the LBA is exactly the same

6. Make the IMG

7. compress it with pops.

8. play it!

Testet on

- FFVII (old=543MB, newmethod=512MB -.-) works

- FFVIII (old=571MB, newmethod=570MB -_-) works

- Ehrgeiz (old=486MB, newmethod=512MB WTF??!) works

BAM

# What are you? — Guest 2007-01-13 11:53

A moron?

# LBA — Guest 2007-01-13 11:59

Your right, it has to do with LBA arrangement, I just tried FFSevens and didnt fix the LBA, but if you take the time to fix LBA it works.

BTW I reccomend doing this with games that are drastically larger ISO sizes than game file sizes, you can do this by checking the size of your ISO, opening it with MagicISO, and then looking at the top it should say XXXMB out of 700MB Max, if its drastically smaller this method will do a lot of good, where as larger PS1 games, it does little good.

# Strange... — Guest 2007-01-13 12:00

FF7CD1 was 741 Mb ,after using CDgenPS2 it became 800+Mb,and compressed eboot is 600+,when normally without cdgenps2 its just 500+ O__O

# Best combination: — Guest 2007-01-13 12:06

Use ISOBuster + CDGEN (if you dont have it, u can do something that starts with Lime and ends with Wire or something that starts with BIT and ends with TOR and RENT)

Export the tree with ISO buster and import it with CDGEN (after adding the files) this will immediately fix the LBA and the arrangement of the files on the disc...

once again, this method is only useful for smaller PS1 games (seeing as they are still burned to 300+MB media)

# Format — Guest 2007-01-13 12:12

I would say you went from BIN->CDGEN or ISO->CDGEN->BIN Use either ISO or Bin/Cue accordingly. my FFVII image came out to about 529 using my method, keep in mind that it depends on the game too. I used the Tetris example to show how much it COULD save, not how much it would.

I have tested the method with:

MMX4

MMX5

MMX6

MM8

Tetris Plus

R-Type Delta (to follow QJ's suit)

Gradius IV

FFVII Disc 1

so far have not had any explosive images (getting bigger that is)

Also, the LBA is a very important factor, tetris and the other worked by pure chance (as unbelieveable as that is...)

The next big step:

An all in one program to do the process:

Take the LBA, and the files, rebuild the ISO via the CDGEN method (if we can get our hands on the source, no problem)

and POPS it.

# hmm — Guest 2007-01-13 12:35

I was wondering this as well. POPstation that's modified can use ccd files to create a file index. but due to the strict format, that will be invalid once the dummy files are ripped out. Perhaps he can make a addon to convert ccd files?

# Compressing Blank data — Guest 2007-01-13 12:38

This is true for certain algorithms:

ZIP and RAR use a simple process for flagging free space:

bits xx-xx + $FF;

this simply sets a range of data that has $FF written to it.

The compression algorithm for POPS doesnt compress Dummy file(s) free space (which is usually randomized anyway, and they typically cannot be removed either) nor does it do that great of a job compressing free bits in an ISO

I.E.:

Tetris Plus.IMG + 566MB

Tetris Plus EBOOT.PBP (Compression LVL 9) + ~400MB

Tetris Plus stripped ISO + 50MB

Tetris Plus EBOOT.PBP from stripped ISO(Compression LVL 9, Ignore CDDA) + ~6MB-8MB

Tetris Plus EBOOT.PBP from stripped ISO (Compression LVL 9, CDDA)+~50mb

# Yes I did — Guest 2007-01-13 12:42

# CDDA — Guest 2007-01-13 12:44

This will keep CDDA information intact if performed correctly, depending on the version of POPS you use, CDDA will either be lost via POPS or will be retained.

# Working — Guest 2007-01-13 12:47

Fixed method: you must recheck the LBA, use ISOBuster to get that to happen quickly, export the tree using ISOBuster and import that tree into CDGEN, this will fix the LBA automatically (uncomfirmed, but it appears to be the fix) also, you can manually fix the LBA for all of your games using a top to bottom LBA readjustment by manually typing the original LBA value into CDGEN (right-click the file, hit properties, check FIX LBA, change the value to the original, original values may be found in whatever ISO extraction utility you used EXCEPT WINRAR [I believe])

# Fix the LBA — Guest 2007-01-13 12:50

Some games will only come out a little to no change in ISO size, this is because they actually do use most if not all of the ISO for files. Also, you can get your MM Legends working by fixing the LBA

use ISOBuster, and export the data tree using ISO buster, put the files in CDGEN and import the Data tree using cdgen's advanced menu

# LBA — Guest 2007-01-13 12:54

Its all LBA problems

If QJ reads this, please add a section about fixing the LBA

You can do so with ISOBuster by exporting a Tree File, and then using CDGENPS2's advanced menu to import it (this is new discovery to me too, as none of my LBA's were changed thru drag + drop?)

also you can fix them manually by comparing the LBA section from whatever ISO utility you are using with the LBA in CDGENPS2, starting from the top, compare the LBA and change it accordingly by:

right-clicking the file, and clicking propeties

Check the FIX LBA box

type in the correct LBA value.

# . — Guest 2007-01-13 14:50

^^You sure? Admittedly, I haven't investigated the zlib compression algorithm that much, but from what I know, it's very similar to ZIP (don't they both use the deflate algorithm?).

Also, try making a "fake" ISO full of null bytes, compression still reduces it to almost nothing.

For your case, I don't really know. This method does strip the RAW data, whereas compression does not. So if you compress something with less data, obviously you're gonna get a smaller file.

# . — Guest 2007-01-13 14:55

# Silent Hill 56.1mbs — Guest 2007-01-13 18:41

used PSX2PSP 1.0.7.1 to extract Silent Hill iso used ultra iso to convert the iso to bin and cue then used this only this part of the

Generic, All-Purpose,

Graphical PSX Ripping guide.

Featuring the PSXLDR Method by TheDragonKeeper

Open PSM Play

Select "Analyze DAO Image" from the File menu.

Browse your computer for the image you just made and select the .bin file

Only check the STR and XA boxes, then hit Start.

When that is done it will ask you if you want to save your data, hit yes. Then for the sake of convenience, put it in the same folder as your disc image.

Now open PSXLDR.

Locate and Open both your image file and psm file.

You should see the raw data on the files that PSM Play found to the left.

Press "Rip All", a message box will pop up when it is finished. Depending on the speed of your computer and the ammount of data that needs to be ripped, this may take a few minutes.

Once that is finished you may close it.

Ok heres where I used PSX2PSP 1.0.7.1 to convert the bin for use with popstation my resulting eboot is 56.1mbs for the game Silent Hill that was a 587 iso, all music works, and game is playable.

I have yet to try this with another game, but if you like silent hill I know it works for that one.

# ISOBuster question — MonkeyLover 2007-01-13 20:14

O.K. I followed all the steps right up to fixing the LBA in CDGenPS2.

When I try to fix LBA and change the value, I get a 'Invalid LBA!!'. One of the original LBA files from ISOBuster is 23, but after importing the FileList (which in Notepad is the correct LBA value) I get a w 31xxx value. I tried to change it as mentioned above and then the error pops up. I also manually placed it in CDGenPS2 and still get this error.

What am I doing wrong? Otherwise like 95% of the other readers I too get the black screen of death!

It's odd that you'd be an unregistered user, what with the level of heat you've been taking for this one, people might be likely to commandeer your nickname and defame you. Plus, offering pre-compiled eBoots, that seems rather... illegal?

# But... — Guest 2007-01-13 20:37

Why you convert the BIN file into a ISO file, so, this method won't work to BIN files????

# erm — Guest 2007-01-13 21:46

MagicISO and ISObuster can open both, so you dont have to convert bin to iso. And I never thought about using a ".iso" instead of a ".bin" cause I know that its better to use .bin!

If you read some tutorials - making an image for popstation - many people say, they had problems with .iso but with .bin everything was fine. So I just opened my FF7CD1.bin with MagicISO (or with ISO-Buster, it should be like the same).

The LBA Problem is old, cause the homebrew programs for the PS2 allways had to have a special LBA on the started-file. Now if the LBA isnt correct on the PSX Games, its the same! The Emulator just trys to start a File with the LBA, but cant find it, cause a wrong file has this LBA.. understood? xD

So i think the easyest method of correcting the LBA is just changing the order of the files in CDGenPS2. The LBA changes too, because of the order...

Argh my english is bad, but no german site is as good as this one. Thanks for being named in the NewsUpdate ^^

Talking about what first started this "reduce fat fast" thing :D, Tetris Plus goes down to 53MG just cause when you re create the cd with cdgen, your are not adding the CDDA AUDIO tracks, so basicly you're doing a "rip" of the game, not the COMPLETE ***** IN 53 MG.

there is no dummie file, he just removed all the music...

# What is PSM Play — Guest 2007-01-14 01:25

What is PSM Play, and how can i get it? Tried google search, and found nothing :(

# alson can try with cd/dvdgen — Guest 2007-01-14 01:35

i will try with sony cd/dvd gen

differences from cdgen ps2?

in cdgenps2 you drop the files, and folders gets the start position all the time (23) and .cnf . scus are the last ones.

on the other program the order of the lba, is determined by order of drag and drop files.

cons: cd/dvd gen do iml file and iml to iso make a iso mode 1 file (psx/ps2 games are mode 2 raw 2352) you need to convert with iso2bin to get a mode 2 raw file :(

# PSMplay sucks.. — Guest 2007-01-14 01:52

I just played a bit FinalFantasy7 on my 230MB version made with the PSMplay Method and ... there were no movies -.-

PSMplay sucks >.

# 2 hours! — Guest 2007-01-14 02:01

after 2 hours of testing both methods you've described, method 1 is the only one that worked for me.

# rip pointless movies — Guest 2007-01-14 02:06

example: GT intro (is good but you dont need to see all the time)

i don suggest rip rpg movies

# on fft — Guest 2007-01-14 03:07

psxdlr dont replace

what happen?

# ok i get it — Guest 2007-01-14 03:21

FFT 59 mb

psmplay method

# movies — Guest 2007-01-14 05:11

xa files are the music str are the movies maybe if you try it without checking str while in pmsplay that may work , I dont personally know cause I havent tried that game.

# Spyro works — Guest 2007-01-14 05:48

I tried Spyro the dragon with the pmsplay method and it works , resulting eboot is 89.4mbs

# . — Guest 2007-01-14 06:23

The program probably replaces the STR files with blank ones so there for you get a much smaller file but you don't get to watch the movies. I would rather have the movies especially for rpg games.

# DISCOVERY!!!!!! !! — Guest 2007-01-14 06:40

PPL I JUST USE THE PMSPLAY METHOD WITH 2 GAMES PEPSI MAN, ISO=300 MB , EBOOT=140MB, AND WITH THE PMSPLAY METHOD EBOOT=60 BM!!! AND IT WORKS I ALSO TRYED TEKKEN 3!!!!!! THE ISO=700 MB EBOOT=420 MB THE PMSPLAY METHOD EBOOT= 50 MB!!!!! AND IT WORKS IF ANYBODY WANTS ANY OF THIS GAMES OR WANTS ME TO CONVERT ANY GAME EMAIL ME TO DAVIDORJUELA4@H OTMAIL.COM IT WORKS!!!!!!!!!! !!!!!

# Not a discovery — Guest 2007-01-14 06:49

This is not a discovery people have been replacing the STR and XA files on games for a long time I sill have a 40kb STR file sitting in my PS1 folder.

This method is only for people the don't care to watch the movies

# Extract pbp?? — Guest 2007-01-14 07:08

Is there a way to extract a pbp file because I dont have the orginal iso left.

# What is the PSM method? — Guest 2007-01-14 07:12

What is the PSM method (step by step)?

Please include a link ti the PSM software. (http://mx.geocities.com/highrojo/archivos/psmplay.zip)

This was linking to an audioplayer.

PLZ HELP!

# Stop following the hype guys!!! — Guest 2007-01-14 09:18

I read all the comments for this method and well from what I gotten from it Im not even going to try it.....not saying it sucks but the method hasn't been perfected yet......Nice try guys but obviously Sony knows something that you guys don't on compressing the PSX games so Im just going to wait for the next update by the great and powerful Dark Alex so see what the key to the compression thing!!!

And just for the record the only program that works for me on the compression thing is PSX2PSP program and I was able to load all my PSX games with no flaws and no problem!!! Thanks!!

# hey hey — Guest 2007-01-14 10:17

why when a try t0 d0wnl0ad this 0r any 0ther stuff fr0m this page, the page 0nly keep refreshing

# MUCH easier way to do all this!! — Guest 2007-01-14 10:33

Just download the program pocketiso (google for it).

Compress the iso with this program and blank (or partially blank the videos) or leave them intact.

All audio files will be emptied and so will still be there just zeroed out.

Now decrompress the file you just made, and voila. You are left with an iso just the same size you started with!

Hmm you say, what was the use then?

Compress the iso now with popstation, and you will see the magic that happened.

Using this method with tetris plus I am left with an eboot of less than 8Mb, and I left the video intact!

Good luck, now lets wait for a good way to compress the sound files!

# test and work — Guest 2007-01-14 11:44

test whit the psmplayer and works fine.

test silent hill and crash 3.

# STUPID — Guest 2007-01-14 11:51

ARE U STUPID CUZ I HAVE TEKKEN 3 IN 30 MB WITH FUCCKING MOVIES IDIOT

# ? — Guest 2007-01-14 12:20

You answered you own question, "bob", and yes, you are a moron.

# Not true — Guest 2007-01-14 13:18

including ripping all of the music the ISO goes down to 6mb

Bwhahah with the music of the Tetris Plus, 53MB

Nice try though.

PSMPlay method will work to shrink almost any game (as it removes a LOT of unnecisary files)

However, this method was intended originally to keep the unnecisary files (and thus the original game) intact, including Music

PSM Play method (Can) get(S) rid of XA Audio tracks and also gets rid of ACTUAL DUMMY FILES (I.E. DUMMY.DAT containing random bits, therefore not BEING EMPTY DEAD SPACE)

My method is to remove the DEAD SPACE from the image

# psmplayer — Guest 2007-01-14 13:21

The audio player is what you want, you can use it to get the list of audio/video tracks from a PS1 Disc image.

# Correct — Guest 2007-01-14 13:24

Essentially the same can be repeated (resulting in 6mb Eboot) by using an outdated popstation to get rid of the CDDA audio tracks in the ISO. My method leaves entire game contents intact, therefore data-filled games arent reduced by much POPS has trouble compressing DEAD space in ISOS.

# @QJ — Guest 2007-01-14 13:27

For those that don't care about videos/and some auido tracks, the PSM Player / Pocket ISO method will work fine, my method was to avoid losing (somewhat) precious Audio/Video data, but to get rid of that Dead space that POPS has trouble with... (hence it not doing much for FFVII) also I am still going to work on this method (even if that means writing my own program to do all three methods in a Input->Output command line program, so be it) until it works with ALL ISOs!

(BTW, anybody wanna gimme tips on where to learn about interpreting ISOs/Bins/IMGs in C++/Java??? if so this woul help)

# video — Guest 2007-01-14 15:00

# Eboot size — Guest 2007-01-14 15:33

Okay so in your first post you said you had Tekken at 50 MB and now your saying it's a 30 MB file with videos. Sounds like your a little mixed up kid

# pmsplay method — Guest 2007-01-14 16:03

Hi I tried the pocket iso method and it doesnt work I Only use pmsplay and psxldr, then just convert and compress the bin to eboot. This method does work better if starting with an original bin file or extracting a bin file from an uncompressed eboot before starting, I have tried this on 10 games and all work and all have music. I dont know how many games are compatable with this method. I do know there are several methods that will help remove files or space you dont need or want, and this thread is kool to help figure them out.

# More sizes of eboots — Guest 2007-01-14 17:24

pandamonium 95mbs

contra 53.2

scrabble 5.19mbs

Intelliqube 23.5

Ill post back with more that work and there sizes.

# no comments — Guest 2007-01-14 18:32

Diablo 625mb -> 331mb

the game has full sound and music!

# plz — Guest 2007-01-14 20:41

I cannot view the files of some of my psx games and I am unsure why this is. The two games I am having trouble with atm are Xenogears disc 1 and Chronocross disc 1.

the size is between does really is 34mb and here is a video http://www.youtube.com/watch?v+SM-PcBnpXWs

# Go Garrett! :) — Guest 2007-01-15 09:41

Garrett.. you keep at it.. i have no idea how to help you but.. i have faith, you started this whole thing im sure you'll try your best to finish the work. sure you'll need a bit of help for that tho.. keep searchin'

and whoever said up there think it was "atownaction" ..that is completely different thing.. we are removing "dummy" files from the images.. not compressing not to be mean but.. speaking of "dummy" files, think you should "remove" your rude comment from the page, Dark_aleX is the man but.. give this guy (Garret/Zero-x) credit for what he's trying to do. ..jerk

# d — Guest 2007-01-15 15:41

does pocketiso always remove the CDDA, or just when you ask it to?

# chess — Guest 2007-01-15 17:26

# "changing the order of the files in CDGenPS2" — Guest 2007-01-16 19:46

Hi DevilGun - how do you change the order of the files in CDGenPS2? I've been manually editting the LBA values, is there a better way?

# FF7 working on 512 mb stick — Guest 2007-01-17 04:14

I compressed FF7 down to 423 mb, using PSMplay. The only thing i did is ONLY compress STR, and NOTHING else!

(I did not use CDGEN!)

# bad link — Guest 2007-01-19 11:11

the link to the tutorial doesn't seem to be working. probably due to the forbidden ISO discussing thing... is there another place where i could read it?

# errrrroooorrrss — Guest 2007-01-19 11:24

When i drag and drop the files over from an extracted ISO (via isobuster) to cdgen, and then try to import the FileList.txt i just get a screen that pops up listing a hundred different errors saying it can't find the directories.

# Working on it — Guest 2007-01-20 18:07

@SolidNeo

Thanks man, it helps to have some positive reinforcement, even though everyone else has shot this down, it *IS* a working method, it just appears that i have a lot of kinks to work out before I get it 100% working..

@RK:

E-mail me with the adress plastered all over this thing (yah, the whole ISO discussing thing does kinda shoot me down, as I semi-posted the link to the tetris eboot.. but not really, I just hinted at where it might be located on a certain server lol)

# yes actually — Guest 2007-01-20 18:10

For those of you running Unix based systems, I reccomend using WINE +P (if you don't know what it is, then you probably wouldnt be one who uses a Unix environment much anyway)

As far as I know, any program that can modify the LBA (which there are several Unix/MacOS based aps that can) should work

Also, Its not that I am unregistered, I am registered in forums as Zero-x, and if people want to Defame me, or flame me, or bring hell to my name, they can go ahead, I released this because I needed to find problems with it, which I was unable to myself, thats part of the deving process, trial and error.

# True, True — Guest 2007-01-20 18:13

This is true, but if you pay careful attention, I never actually say to do THIS, or do THAT...;-)

# Final and end to my posting on this until a final version is released on how to do this — Guest 2007-01-20 18:20

HOW DARE YOU QUESTION QJ'S NAME!

Ripping ISOs of your OWN GAMES is NOT ILLEGAL:

That is considered a software backup, which you are entitled to by end-user rights, This was not the case with ripping Cartridge based system as a lifetime warranty on the chips and battery inside them was offered, however with CD-based media, no matter how well kept a CD is, it could very easily go downhill, providing a way to backup the game is not illegal, however there is no method of which to play that game that is legal (technically modchips arent illegal though...)

Anyway, Thanks for supporting me (those who did)

And to those who doubt my method, I still stand by it, and will eventually work out EVERY ISSUE WITH IT! (And will stick by and continue finding the way to get thru to the goal with my method!)

As far as the illegalities of some of the things I may or may not have posted:

One: Unregistered user, that MAY or MAY NOT have been me

Two: Tetris Plus is owned by a now defunct company "Jaleco" which to my knowledge wasn't the original owner of tetris anyway. the concept of Tetris is intellectual proper of the Tetris orginization, which actually has no copyrights on any but the first Tetris games code. Technically the Tetris Plus game has no copyright attatched to it anymore, thus why I decided to offer it publically as the game is no longer being manufactured, and the game is not owned by anyone.

Software Piracy is the STEALING of software that you do NOT LEGALLY OWN A COPY OF.

Anything else (ripping, burning, etc.) is legal, its jsut COPYING your own Software

# no eboot to iso program? — Guest 2007-01-21 07:48

i guess there isn't a eboot to iso program i would assume. so anyone trying to do this with a eboot file all ready don't even bother.. its a headache. informative info without being able to click on the jump if youre not a registered user for their site, and the fact that even if you register you still wont be able to view it unless youre a premium member, whatever that means. its informative with alot of headache site.

# yes eboot to iso program! — Guest 2007-01-25 11:01

the forum thread was removed because of an illegal link. and the Popstation GUI has a Eboot-to-ISO conversion tool in it :)

# FFVII Work — Guest 2007-01-28 18:34

I got it working normally, its got nothing to do with mod chip protection (BTW it was the old EA games that had that). FF7 works normally, as does 8 and nine.

I havent tried this, but from reading everyones' comments about it not working, I am probably not going to try it.

# LBA problem? — Guest 2007-02-03 18:05

does Breath of Fire 4 work with this? i've dumped my NTSC game and after doing these, it still doesn't work.

normal method = compressed to 180mb iso, black screen.

manually editing LBA values in CDGEnPS2 = 1gb iso, compresses to 160mb, but i got a black screen.

using file tree export/import = 470mb, compressed to 230mb, black screen.

i'm now stuck and puzzled. btw, there were read errors from the ISO. i had to ignore them. (i extracted the ISO from the original eboot that worked, which was around 270mb.)
