Sorry guy this machine is pissing me off. But ive just noticed a fadded sticker on the game rom only thing i can make from it is
GOT
SYS80B
Test
Im assuming this is a test rom should i still get displays with this installed as ive replaced all the the Riot chips half of all the others and still getting the same results? Ive replaced the crystal and the ics for the clock circuit just incase
Any help would be great or should i just order a game rom for it and go from there
