Neo-PCM2 PLAYMORE 2002 code for FBA
FerchogtX:
Hi guys, if yiou noticed that mame code, this will not be surprising XD, i hope this works...
neogeo.h
look for this:
--- Code: ---// neo_run.cpp
--- End code ---
add this after:
--- Code: ---extern int nNeoPCM2PLAYMOREByteswap;
--- End code ---
neo_run.cpp
look for this:
--- Code: ---int nNeoSRAMProtection = -1;
--- End code ---
add this after (or after pcm2 code by IQ_132)
--- Code: ---int nNeoPCM2PLAYMOREByteswap = 0; // PCM2 PLAYMORE chip
--- End code ---
Look for this:
--- Code: --- if (BurnDrvGetHardwareCode() & HARDWARE_SNK_SWAPV) {
for (int i = 0; i < 0x00200000; i++) {
unsigned char n = YM2610ADPCMAROM[i];
YM2610ADPCMAROM[i] = YM2610ADPCMAROM[0x00200000 + i];
YM2610ADPCMAROM[0x00200000 + i] = n;
}
}
}
--- End code ---
add this after (or after the IQ_132 PCM2 SNK 1999 code)
--- Code: --- /* Neo-PCM2 PLAYMORE(c) 2002 Sound Chip Emulation */

--- End code ---
look for NeoExit() int add after:
--- Code: ---nNeoSramProtection = 0;
--- End code ---
this:
--- Code: ---nNeoPCM2PLAYMOREByteswap = 0; // exit PCM2 PLAYMORE chip
--- End code ---
d_neogeo.cpp
according with the driver give the correct value for each ga,me that uses this chip, for example:
--- Code: ---static int kof2002Init()
{
nNeoProtectionxor = 0xec
pNeoInitCallback = kof2002Decrypt;
[B]nNeoPCM2PLAYMOREByteswap = 1;[/B]
return NeoInit();
}
--- End code ---
see ya!!!!!! :D
P.D. Edit, svcchaos and ss5 cases were swaped XD, deleted all amp references... that wasn't declared :confused: fixed ss5sp case, used ms5 one XD deleted svc chat table (svc and ms5 uses the same table, thanks to IQ_132 :P) now svcchaos ans ms5 uses the same case.
Edit2: readded case for svcchaos, mem offset is different from ms5 one XD
DsNo:
Thanks very march.. FerchogtX!!
Perfectly work!!
and Changed ( & ) to ( & )... :D
iq_132:
Here's my version :)
FerchogtX:
Great man!!! :P BTW I fixed the src i posted in the first post, now it will work without probs, and cleaned a lil
See ya!!!! :D
P.D. Fixed again the driver XD
iq_132:
Try this code:
neogeo.h
look for this:
--- Code: ---// neo_run.cpp
--- End code ---
add this after:
--- Code: ---extern int nNeoPCM2PLAYMOREByteswap;
--- End code ---
neo_run.cpp
look for this:
--- Code: ---int nNeoSRAMProtection = -1;
--- End code ---
add this after (or after pcm2 code by IQ_132)
--- Code: ---int nNeoPCM2PLAYMOREByteswap = 0; // PCM2 PLAYMORE chip
--- End code ---
Look for this:
--- Code: --- if (BurnDrvGetHardwareCode() & HARDWARE_SNK_SWAPV) {
for (int i = 0; i < 0x00200000; i++) {
unsigned char n = YM2610ADPCMAROM[i];
YM2610ADPCMAROM[i] = YM2610ADPCMAROM[0x00200000 + i];
YM2610ADPCMAROM[0x00200000 + i] = n;
}
}
}
--- End code ---
add this after (or after the IQ_132 PCM2 SNK 1999 code)
--- Code: --- /* Neo-PCM2 PLAYMORE(c) 2002 Sound Chip Emulation */
// some code by Fataku & some by the vconv (from 2ch) - FBA conversion by iq_132
if (nNeoPCM2PLAYMOREByteswap != 0)
{

int value = (nNeoPCM2PLAYMOREByteswap-1);
UINT8 *rom = YM2610ADPCMAROM;

ofst ^= addrs[value][1];
rom[ofst] = (buf[((i + addrs[value][0]) & 0xffffff)] ^ xordata[value][(ofst & 0x07)]);
}
free(buf);
}
--- End code ---
look for NeoExit() int add after:
--- Code: ---nNeoSramProtection = 0;
--- End code ---
this:
--- Code: ---nNeoPCM2PLAYMOREByteswap = 0; // exit PCM2 PLAYMORE chip
--- End code ---
d_neogeo.cpp
According with the driver, give the correct value for each game that uses this chip; for example:
--- Code: ---static int kof2002Init()
{
nNeoProtectionxor = 0xec
pNeoInitCallback = kof2002Decrypt;
[B]nNeoPCM2PLAYMOREByteswap = 1;[/B]
return NeoInit();
}
--- End code ---
btw, I think "nNeoPCM2PLAYMOREBitswap" would be more appropriate.
btw2, All the code except the main body is a complete rip of Ferchogtx's (Just so everyone knows)
