Okay, I've recapped the board and it turns on but of course there is totally garbled shit on screen with absolutely no sound and I cannot see anything, so I of course also cannot access the test menu.
I tried to read the eproms and not a single one of them was read properly. Either it wasn't able to read at all or it was just reading something weird that wasn't corresponding with the epr from the rad mobile mame set.
While ordering eproms I just realised that the MPR Maskroms where you suggested I should replace them with 27C800 have infact 32 legs. 27C800 has 42. How can they be pin compatible and how am I supposed to fit them? @Apocalypse and anyone else who can help me
EDIT: I see, you were talking about 27c801. Nevermind
