Topic: one question about cps1/2 program

[lxd_bruce]

NeoGeo system uses "Neo68KROM" to represent NeoGeo program.

How about CPS1/2 system？

"CpsRom" or "CpsCode" ?
 

[Barry Harris]

Both.

CpsCode contains the decrpyted OpCodes and is used via FETCH. On CPS-1 CpsRom and CpsCode are the same - but with CPS-2 they are different.

thx

however, I have another question.

I wanna patch a game to make a new driver. The game is sfzj (Street Fighter Zero (Japan 950727)).

The patch is a Boss hack by Yumeji.

the hack should be patched on these two roms: sfzj.03c & sfz.06.

the former is encrypted while the latter isn't.

here is my driver. It doesn't work. I don't know why.

Code: [Select]

// Street Fighter Zero (Japan 950727 / boss)

static struct BurnRomInfo sfzjbRomDesc[] = {
{ "sfzj.03c",     0x080000, 0xf5444120, 1 | BRF_ESS | BRF_PRG }, // 68k program

Anyone can help? 

[iq_132]

The Boss-hacked program roms are encrypted?  What you will need to do is use that boss-hacked program, dump the decrypted code -> CpsCode Then compare the dumped code from the boss hack to the dumped code from the original.
If you don't mind posting patches for this sfzj hack and that vamp hack also, I'm sure I can come up with something for you.

[lxd_bruce]

Of course not.

Here are the patches

Thanks in advance.
