Woohoo i hope it is faster now *finger crossed*

Now zelda minish cap will be even more fun



@post 1: use google and search for it!

yeah baby, i am lucky to have a 1.5 and this is a great inprove ment, the sound is a bit better and the speed too. i cant wait until this thing is in full speed with kerneal mode.

anyone tried it? i cant be bothered yet as the last one said it was much faster but when i put it on it ran like a fat boy chasing a tortoise......!!



and this one doesnt mention speed improvements

Any roms that play at a workable speed?



my completely random testing is showing 6-8fps, with garbled sound for most things ;)

Hmm I think ima wait till a few more versions come out. Keep up the good work though! :)

even rpgs run mega slow and it crashes every time you try to exit!

I tried the first golden sun rom running it with sound, no frame skip and my results were a locked 10fps



the sound is still horrible but was a improvement over the last version



here are some screenshots ;

ZX - thanks for the continued work on this project - I would rather have small updates twice a week than one major update every other month...thank you. If you read these, could you explaine why (using small words so I'll be sure to understand) it is so difficult to get this emu running when SEGA, SNES and NEOGEO-CD are near, if not, perfect? You are a great and dedicated coder, do you have any future plans to work on a MAME project?

Will we ever see 30-40 fps with good sound?

I know some people who are too poor to buy $20 GBA games will like this work, and since they can't afford stuff they don't care that games run slow. You know what those cheap dirtbags say, slow is better than nothing.



But good job zx-81, you made some people very happy. :)

I was wondering how sony can get ps1 games to run at full speed on the psp



do they just create an emulator for specifically for one game so they can tweak it for that games needs



this seems the harder but more sucessful way as i read someone was making ott on the psp work using this method

Proberly the PS1 runs well because they have a similar processor structure or are simialar in some other ways so that its not really emulatinng just decrypting the ps1 roms and running them. I don't know exactly thats just a stab in the dark. @ZX-81 Nice one castlevania runs 100% 10 fps. And that works well for me.

Perhaps the sound emulation still isn't optimised yet on the ME, because when I enable sound emulation, I get drops in speed.



This will improve, of course. I have full faith. And I'm happy he's not dropping or slacking off. He rocks :)



Hi zx, can you tell me whether the ROM is loaded entirely in RAM? I'm 95% sure it is, but I just wanted final confirmation



Also, will sources be released for this version? I want to try my own lil' "hack" and see if downclocking the GBA main CPU would have any beneficial or anti-climatic effect. ChanKast, the Dreamcast emulator, has this option for slower machines incapable of fully running the emulated DC CPU at full speed.



There are also ways to overclock the PSP CPU past 333MHz, to 366 ;)

Great work! I have one problem I can't figure out. I have a v1.0 firmware unit and up until about a couple releases ago, I was able to use PSPBREW to convert the 1.5 eboot down to 1.0, but ever since the last couple rleases, upon trying to convert the PBP to 1.0, PSPBREW gives me an error of "invlaid PBP". ANy idea what's wrong, or how to enjoy the emu on firmware 1.0? perhaps theres a better convberting program? Thanks much.

Thank zx-81 for adjusting the gbaflash :) made the game much better without pausing every 10sec

sony is making all the ps1 games in to eboots so you can run them on the psp so it isnt really a emulator. the eboots of the games were tweaked so they would run perfect on the psp.

WHAT?! not for firmware 2.xx?

Thanks z-81!



I can only hope that someday we get up to 80%

Awesome work zx, I'm looking forward to the next release!

....Now that it has a Media Engine, how about a Speed Up Engine? I've seen details added to this emulator lately, how about at least an update on speed? I don't mean to be bossy or anything, but yeah, speed's more important than better looking icons and more features, although having better graphics is a +. Keep up the good work by the way. Hopefully we can see a full speed version of this emulator by the end of this year.

Come on guys stop moaning that its slow k. Its still in early stages.... Just wait a little, zx-81 will improve it over time.

Though there is a Downgrader for 2.xx, I dont want the risk of bricking my PSP for an Emulator. I rather just have my 2.5 with the eLoader. and for zx-81. "Do the Ri' fing! be MEN!"



Make VBA for the 2.xxs' out there! ...please?

To do that to a PS1 game isn't hard. Lets assume that clock speed and other parts wern't a challenge,altho ugh they are,but bare with me.



Even in this fictitious world where the PSP was somehow as powerful as a PS2, we still need to factor in Game Size.



PS1 Game = Max700MBs Per Disc.

PS2 Game = Max 9GB Per Disc. Not Gonna happen.



Considering that this is before factoring in things like RAM, and clock speeds, its still impossible to get 9GB of data onto a PSP.



To zx-81:



25 is not the actual number, 25 is basically the theoretical number. You need 25x the clock speed before even considering it. However, it could be lower. I have no doubt that the PSP can run GBA games 100%, even without having 25x the GBA clock speed. What the emulator needs I presume is to be optimized, programmed to use other things, like the PSP's graphics card to offload some of the duties, and time. Using the ME is a start, since it offloads the work off the CPU.



Also, the number can also be far lower than 25, provided they use identical procs, such as PSP>N64, since they're both MIPS.

Does the sound still sounds like its blowing up the psp? on the version before this, thata I have, The sound nothing but noise.

From Wikipedia:



* Supported Disc Media: PlayStation 2 format CD-ROM, PlayStation format CD-ROM, Compact Disc Audio, PlayStation 2 format DVD-ROM (4.7 GB), DVD Video (4.7 GB). Later models are DVD-9 (8.5 GB Dual-Layer), DVD+RW, and DVD-RW compatible.



Yeah, you're right. Still, you can't put 4.7gb on a PSP. Even if you could, its still not practical, as noone would have that, if it was possible. [end reduncant sentance]

Yes they can.... double layer..

Congrats, you've achieved a new level of stupidity.



1. The PSP is missing an analog stick. Few PS1 games need it, almost all PS2 games do, not to mention R2+L2



2. UMD = 1.8GB, Max.



3. Even if there was an 8GB MSPD, how much would it cost?

-----2gb is at least the cost of a PS2? Therefore, an 8gb would be such a waste of money, and would probably cost 500+.



4. Still, the PS2's EE = 294MHz. PSP = 333. Therefore, considering that it has to be at least 25 times, according to zx-81, its impossible. Hell, even if it was only 2 times required, its still impossible.

So glad to see you read and respond to comments - let me speak on behalf of everyone who appreciates your work when I say please ignore the bashers, they really have no place here. You answered part of my question @32, and I thank you. You also quickly fixed the exit problem, and we all thank you...Just a few questions: Would you consider taking on a MAME project, can you fix the Gameboy emulator sound problem (after exiting and loading another game, the sound doesn't work) and, if you do not beleive that full speed and sound on the GBA is attainable, how do you know when you're done?

1. On amazon they said it was only gonna be liek 300, and prices go down real quick remember how much 2 gigs used to cost? And few ps2 games use all that space, msot will fit on one umd anyway. As for the analog thing they would have to rework it just like they are reowrking the r2 and l2 of the ps1 controller.

you got riped off for $40 or alittle more you could of got your self a 4gb.

Most PS2 games do use the full space, and still, even if you buy a MSPD that would hold 8GB, although you can't, it is still far too impractical. Not to mention that Sony cannot distribute it, since its too big for the internet (avgpersons), and too few people would have it. If a 4gb stick is 160ish, then an 8GB would be about 300, provided it existed, and thats with any and all price drops taken into effect. Noone is going to spend an extra 300 on top of a unit that is already expensive.



You cannot rework controls, that only works when there are extra buttons. Considering that the layout on the PSP is identical, you cannot remap this. Only I believe 11 games use the DualShock on the PS1, so that means that only 11 games could use both analogs.



What are you gonna do about the lack of the right analog, R2,R3,L2,L3? These aren't used on the PS1, so it doesn't pose a problem. Sony isn't reworking it, since those buttons aren't used.



90% of PS2 games are over 1.8GB. Pwned.



You still haven't explained how a PSP can emulate a console more powerful than that. When you explain your logic, I'll go play Xbox on my PS2.



For 74, the one who doesn't have a life is you. If you have time to come in here and *****, your life is really lacking.



Also, 2gb, here, in canada, is over 129, the cost of a PS2. This is not to say you cant get one for cheaper, I'm using normal pricing.

Guys, why don't u leave strangler alone. He wasn't trying to start a fight, he was just asking a question. Maybe he didn't know all the facts, I mean I didnt know a psp disk could only hold 1.8 gb or whatever was said above. I think what he meant was why dont they just release ps2 games on umds, like ports kinda, formatted a little, but since someone stated the size of umds, the chance for good ports of ps2 games doesnt look too good. oh and btw some people will spend an extra 300 for a bigger memory stick, and the prices are bound to go down, look at how much prices have gone down already. When i got my first one (128) it was like 50 bucks, now u can pretty much get a 1 gb for that

zx-81, could you make a turbo button and release it in the next version? That would help a lot for some very long cutscenes, and the start button is free.

Tales of Destiny 2 for PSX is Tales Of Eternia for the PSP. But there is a Tales of Destiny 2 for the PS2 which is a completly differnet game.



So.....

He used KH as an example, which is pretty big. While many games don't fill the entire disc, many are over 1.8 gb, rendering UMD distrobution useless.



PS1 emulation on computers works. PS2 doesn't.



Also, TOD2 I think is PS1.

i got my 2gig car for Amazon for 20Pound just 20 pound so who ever pays more than that has been ripped for sorry they have and i payed 125 for my psp with 2 games so HA HA my specs are 1.5 FW (the downgrader works i got an Auto installer with all files accept one that i got a hold of and as for this GAMEBOY thing its slow realy slow

such a great developer! amazinbg progress from what we had a mere month ago. this emulator should be up and running in a month because your updates are so fast!! btw think u can release the necxt version before i go on vacation this saturday ^_^ i challenge you

First off all thanks to Zx-81 for his work improving GBA emu with so much dedication. Also very good for you to answer questions in the comments page. Dont listen to those lamers that say ***** and expect everything to come to their hands with no work those are lower than crap and contribute nothing. Just the point that you work not or fame glory or money but for the challenge is really something... O_O!!



So Zx, when you get the emus you are working on to what you expect in terms of speed sound, etc... whats next? PDA like functions? A custom firmware with a whole new UI? Collaboration with others devs to hep them in their work? (like the n64 emu)



What would you like to see the PSP doing?



Thanks!!

"The PSP is max 333Mhz."



"That's only if they deliberately limit themselves to a single PSP CPU, there are two of them, and there's nothing stopping any programmer from using either CPU for anything they want, it's not limited to sound processing the way the're currently using it."

You can only use multiple UMD's for linear games. Also, 2 UMDs still isn't 4.7 gigs.



Have you explained how you can emulate a console missing 4 buttons and an analog stick? KH uses both analog sticks, L2,R2, R3, the Dpad, Start and select, and all four face buttons. Therefore, you can't play it using the PSP's controls.



Even if you use both CPU's, that gives you 666MHz. To emulate a PS2, you need at least 3GHz. Therefore, even the computer I type this on can't handle it.

See up at the top, the FPS counter? Its not even 10FPS! Therefore, you can't even get 1/6 of the speed of a PS2, even on a computer that's more powerful than a PSP.
