Often RAM and ROM isn’t tested when the CPU can’t see it - so it’s on the other side of a custom chip and only custom chips manipulate it - they’d have to add loopback hardware at expense to self-test it.Įmulation accuracy also tends to tail-off at the point where the CPU dumps graphics codes into RAM - after that, they dont model the individual IC behaviour - they just do the best interpretation with modern computer hardware to make things look correct. ![]() Dirt Devils, Sega Model 3, Sega, Sega, Racing.
