Hi folks. I've received some cps1 games and a-boards for repair. Amongst them, a street fighter 2 world warrior that is driving me crazy.
The customer said "no audio", I found a broken chip and swapped for a good one. Audio came in. Ok, let's test it... game starts apparently ok, but when I coined it:
some graphics are gone, and partly some backgrounds (just in the right part of the screen). In fact, the backgrounds are there but "hide" as I move the character.
Any ideas? I've tested the program roms, audio roms and PAL chips (still not the IO one). I'm afraid of testing the graphic proms, since it seems not compatible with 27c4096 as my programmer just read them full of FF(hex)
