Hi guys

I have a "kof98 mvs cart" here, it boots but it has graphics problems. It looks like its all pixelated and the sprites are mirrored, the sound works.

Any help with what I can do to fix it? I've posted some images of whats wrong with it and also some of the board scans.

any help would be greatly appreciated, thanks

Checkout the section on C Rom lower address lines.

Thanks, ive already looked at that but unfortunately I dont really understand it :(

Is there a more simple way of understanding whats wrong? I'm guessing it has something to do with the C roms? problem is I dont see any broken traces on the "CHA512y" board.

Is the fault located on the "PROGSF1" board?

thanks

bump

any ideas anyone?

if anyone can at least try and give me an idea of what board or what chip could be the faulty one or where I could be looking at? It would be very appreciated.

Try looking for cracked solder joints on the underside of the CHA board.
