I recently bought a pinball machine (Bally's Space Invaders) and was suprised
to find that the thing is controlled by a 6800 MPU chip. Being the glutton
for punishment that I am, I am considering rewriting the ROM program. The
only problem is that disassembled code is pretty tough to crack sometimes,
so I really don't know where to start. I have a SWTPC 6800 system, and I
[kknow 6800 machine code, so that's not a problem. Has anyone tried anything
like this before? I have seen video games with 'aftermarket' ROM chips in
them to make them harder (Galza, Pac-Man (ick)) so someone out there has done
it. How?
