I just acquired this Zed Blade cartridge. The game passes the UniBios CRC check, and the game plays fine. However, the music for the last stage (0x072B) is just straight static.
Opening the cartridge up, the majority of the chips are mask roms, but you can see that S1, M1 and P1 are EEPROMs. There is an SNK sticker on them which hints at a factory repair. I didn't take pictures of the backs of the boards, but they are both cleanly wave soldered with no signs of tampering.
What are my options here? Can the S1 EEPROM be reprogrammed to fix that static track? Should I try to scavenge the correct Mask ROMs from a damaged board?
