Hmm.. Give me a little while and I'll figure it out

**iq_132** · May 14, 2004

Actually, I figured it out already

You want to find this:

  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;
 	}
 }
}

and put the main body of code after it ( The if (nPCM2Value != 0) part)

For some reason there is some code in a different place in my fba source.

hmm..is there one for kof2001 and 2002??
What troubles are you having for kof2001?

Here's the code for kof2002 (mame set)

http://www.freepgs.com/iq_132/pages/games/kof2002.html

well..I've never seen decryption for the encrypted set to work on fba...where can I find it?

nm, I got everything now

damn Iq, how come you never told me about your site? that place rules!!

@noobs who might be reading...no!..Iq's site does not contain roms

**Weirdy** · May 15, 2004

Actually, I figured it out already

You want to find this:
  if (BurnDrvGetHardwareCode() & HARDWARE_SNK_SWAPV) {
 	for (int i = 0; i < 0x00200000; i++) {
   unsigned char n = YM2610ADPCMAROM[i];

   YM2610ADPCMAROM[0x00200000 + i] = n;
 	}
 }
}
and put the main body of code after it ( The if (nPCM2Value != 0) part)

For some reason there is some code in a different place in my fba source.

wait, where?

oh, btw, I'm getting this error

ok, nm, I fixed the kof2003 problem, but now I have a problem with ROTD

I did what you said to do on your site and I all I hear is that...static-ie sound...

how do I fix that?
