CPS2PSP Kernel Mode version out now

Posted Sep 22, 2006 at 5:22AM EST by QJ Staff

Listed in: Homebrew Emulators, Emulators Tags: Capcom, CPS2PSP, eLoader, NJ, psp homebrew emulators, Supercomputer, TIFF

A few weeks after NJ released the last beta version of his newest conquest, the CPS2PSP emulator. He has finally unleashed the fruits of his labor with the first ever version of the CPS2PSP; and no, he has not debunked rumors that he is an advanced supercomputer and not a live, human being. Perhaps, he just doesn't have the time for all that senseless blabbers since he's just so busy perfecting this emulator.

But regardless of his real identity, we think that everyone will agree with us when we say that this guy churns out amazing emulators. NJ also released a kernel mode version of CPS2PSP ver.1.0, but before we go there, let's first focus our attention to the changelog:

romcnv.exe was renewed to ver.5. Referring to details converter/readme.txt.
The mask processing of sfa2 and progear re-correction.
Correcting the mask processing of the opening demonstration of sfa3.
Correcting the trouble which the character name of msh is indicated to the rear of the character.
Because with mmatrix it has frozen after the name entry, correction.
Decreasing the size of cash file of mmatrix.
Correcting the mask processing of the ending of dimahoo.
The prayer number of people which are set with [sabisumeniyu], value of the coin input port just in the input button
Way it reflects, correction.
The specification of zipname.dat a little modification.
Empty memory approximately 1MB increase. (As for Kernel Mode edition approximately 1.5MB increase)
Initial value of AUTO Flameskip modification to OFF.

We have to admit that our Japanese is useless, so if someone could hook all us up with a translated readme.txt, that would be really nice.

Going back to the CPS2PSP ver.1.0 kernel mode, NJ mentioned some info that eLoader users should take note of. When you're using this under the TIFF loader, you should add the text below to the appropriate file.

Does Marvel vs Capcom actually run at "FULL SPEED"? Can someone else varify? That would be the greatest!!!And is this strictly for PSPs 1.0 , no 1.5?

# Difference between normal and kernal mode versions? — Guest 2006-09-22 08:08

What's the difference between the normal one and the kernal mode one? I have a 1.50 PSP, and I don't know which of the two to get. Can someone please tell me which to get, and why? Thanks.

# Guest 2006-09-22 08:15

can anyone confirm if this makes games play faster (for MVC)>?>

i'm at work !!!

# Awesom — KaVaYo 2006-09-22 08:28

It already run perfect but anyway... Nice to see improvements in this wonderful emulator. D&D ToD and D&D SoM are the best! You know what I mean...

# my test — Guest 2006-09-22 09:29

I have a 1.5 psp and i've tested a few games with this new version and the games that had a bit of slowdown before do seem to be running faster (eg sfa3, mvsc)

I also don't understand what the kernal mode version is

so if somebody could explain, thanks.

# AT #10 — Guest 2006-09-22 10:01

The rom that you're trying to run does not work. All you need is the clone of this rom "mshvsfu1".

Just get "mshvsfu1" which is the US version of the game and it will work fine. Make sure you have both roms "mshvsf" and "mshvsfu1" in your roms folder.

Hope this helps you out son...

# WTF — RoMLesS 2006-09-22 10:24

is anyone else having this problem? im trying to get the cache files for my roms, but everytime i drag any rom into the convert program, i get an error saying"error rominfo.dat not found" i was trying my roms from beta5 version of cps2,which btw, all the roms i have there worked.and still i wouldget that error, so i DLed one of the roms all over again, and still the same error. can anyone tell me why im getting this? i cant see what im doing wrong, isn it the same steps like the previous cps2 betas? take the rom drag it into the romconv program in converter folder. take the cache from that folder stick it into the cache folder in your psp/game and the rom and clone roms go into your rom folder.these are the correct steps so why am i having problems with it?

# Guest 2006-09-22 10:24

what type of roms you use for this? mame roms made by capcom??

# @ #19 — Guest 2006-09-22 10:44

had the same problem. you have to double click on the romcnv program and select the rom that way. can't drag it.

# MVSC — Guest 2006-09-22 11:29

for those who asked ,yes MVSC does indeed run much better

here are my specs

no sound

333mhz

no raster effect

stretch to 16:9

F/S 5 (30 FPS)

i get 100% most of the time on gameplay

# kernel — Guest 2006-09-22 11:36

wat iz kernal

# Kernel — Guest 2006-09-22 11:42

en.wikipedia.org/wiki/Kernel_%28computer_science%29

# kernel mode — Guest 2006-09-22 11:52

For those who don't know what this means, code that runs in kernel mode (i.e. the PSP OS/firmware) is protected by the PSP hardware (CPU). Code running in user mode (games, apps) cannot access memory used by the kernel.

This means that at the moment, unsigned code can only access things that games/apps can access, such as the screen output, sound output and button/d-pad input. Unsigned code can only be run in the area of memory exploited by the buffer overflow (64Kb). In order to allocate enough RAM to run proper homebrew (e.g. emulators) kernel access is required. Only kernel code can allocate memory to user processes (homebrew). This is where we are at the moment. In order to get a fully exploited system, the kernel needs to be attacked. Then the PSP will be under total control of the homebrew code.

There are different layers of protection between user mode and kernel mode. Think of it as an onion where kernel mode is the core and user mode is the outer layer. As you remove the layers and move up privilige levels, you get closer to the kernel. You can make system calls in user mode which instruct the kernel to do various things but these calls are always controlled by the kernel and are not easy to exploit. By using system calls, it is possible to increase your privilige level and get closer to the kernel (peeling the layers from the onion). This will however take time and a lot more hardcore hacking to achieve.

# Full Speed — Guest 2006-09-22 12:20

Yes, this looks fantastic.

Heres a tip for everyone. you may notice that there is ALOT of access to the memory stick during emulation, so if your seeing alot of slowdown and you also see the memstick access light going nuts then the speed problem might not be caused by the emulator but by your memory stick.

Its commom knowledge that sandisk ms' have faster access rates, if you got one but dont have this emu on it, try that out.

This is a fantastic emulator. very sexy :)

For some reason I keep getting an error message when I try to boot up the gameplay. The only file I don't have is the ini

# CPS1 — Guest 2006-09-22 23:47

this is all great but id personally rather have a faster cps1 emulator, have you forgotten about that NJ?

# Guest 2006-09-23 22:04

Can I use MAME clone files next to my CPS ROMS?

Do both files have to be CPS originals in order for this to work on NJ's emu?

Do I have to create to versions of Cache, one clone version, one rom version as well, or only one version from the ROM and not the clone?

Any hints as to were I could find good CPS R#$MS?

Thanks for the support!

# Guest 2006-09-24 10:07

@#31 irc is a good place to look

# can u play x-men vs street fighter — Guest 2006-09-27 07:53
