ps2 mame

[evilo]

Hi guys,

believe me or not, but I've only tried ps2mame for the first time yesterday...
and I must say this is a very very nice piece of code :)

now, the question I'm asking myself... where is the source code... !!!!

just amazing !

Just for information :

It's possible to patch ps2mame to use a PAL video output using the ntsc to pal patcher from Jayteemaster. (Guaranteed, I used it to play mame on my PAL *only* TV)

url is : http://www.geocities.com/jayteemaster2003/

Also, may be it would worth the pain to put it as information on the ps2mame section ??

Uhh....www.mame.net ???

The PS2 port source might not be there though...dunno where it is.
There is a PS2 mame port at playstation2-linux.com in the projects
area, but not sure if its the same one you can download from ps2dev.

No, unfortunately, this is not the same one,

the one you are talking about is a port of xmame (using SDL or X11) and running under the SCE linux environment, while that one is "stand-alone" port made using all fabulous things available on THIS site :)

still playing with mame, I replaced the "old" sjpcm lib v1.0 with the v2.0 (uses less memory than the 2.1), and noticed a few fps increase...

for example rygar is now playing full speed !
even shinobi seems to be smoother ....

is it just me ? kind of psychologic effect ?
did anyone else tried it ?

anyway it uses less memory (about 100kb), so it's still good !

[EDIT]

While playing G'n'G (Best game ever, and full speed!), I notice that the sound emulation is too fast... from what I understood, the SjPCM_Enqueue fct is certainely called in the sjpcm lib with NTSC parameter size..

so my question is : how could I dasm the elf, find the fct call and modify given parameter (to set it according to PAL)..
I've tried with PS2DIS but without any concrete results.....

for people interested I post "my" PAL version there : http://www.webalice.it/sbasile/pub/ps2m ... 16.05p.zip

Code: Select all

objdump -d yourfile.elf

should work, but you may need to postprocess the output to get the assembler to read it. At least you can see what's going on and use it to hexedit the bytes that interest you. objdump is part of binutils, so it should be available in $ps2dev/ee/bin

evilo sorry which Mame version do you have. I have a version that has many problems, shinobi flat out refuses to load as do many other games, old ones work. I tried that link but I think it's dead, any help much appreciated, Steve.
