Actually, I figured it out already :lol:

 

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.

wait, where?

 

oh, btw, I'm getting this error 

src/burn/neogeo/d_neogeo.cpp: In function `void
  cthd2003_neogeo_gfx_address_fix_do(int, int, int, int, int, int)':

I changed the kof2003 driver to the set named "kof2003b" (b stands for bootleg) so I can identify it as being bootleg

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?

is that where you wanted us to put the nPCM2Value=16; ?
