cps2 roms?

stealth phoenix, that's a catchy name.

coincidentally, i've used mame plus myself for debugging my romsets.
thanks for making a custom build available!

 

No worries! Hopefully the MAME Plus guys will pick up on that name too.

 

Did anyone ever figure out what the decryption keys to Rockman Power Battle are? I seem to recall that being the last game to decrypt.

 

yeah, haze found code in the cps1 version that was the same as the cps2 version and nicola used that to figure out the key.

 

Info here, for those whom may be interested. http://haze.mameworld.info/2007/09/09/cps2-generation/

I've found Haze's site in general to be a very good read.

 

Strange, FinalBurnAlpha still doesn't support it, and the encryption keys between FBA and Mame are entirely different for some reason.

 

The reason is FBA stores data as 16 bit little endian when MAME stores it like the original hardware (big endian)

 

Uh... aren't there routines to flip this?

 

Code:

unsigned char a, b;
while (!feof(in))
{
     a = fgetc(in);
     b = fgetc(in);
     a ^= b;
     b ^= a;
     a ^= b;
     fputc(a, out);
     fputc(b, out);
}
