Out of curiosity, why did you have to replace the the P1 rom chip? Did it just suddenly go bad or what?
What reason would there be to replace a chip other than it went bad?
Just curious about the technical details behind it. Sound glitches? Graphical glitches? Game didn't work at all? Unibios CRC checker said it's bad?
I didn't think he replaced it just because he thought it'd be a fun way to spend the afternoon. :P
