Hey guys nowadays I am trying to repair a faulty Super Cobra bootleg board.
The game boots and displays video, but it's garbled.

I have reprogrammed all the eproms with original files first, but the behavor is still the same.
I can see somebody removed and socketed the NEC D8255AC-5 at position 1E.
Everything else looks ok.
Board has 5 rams at 10b-10f (Motorola MCM2125AC45). Do you think this behavior is caused by faulty ram?
Thanks for any hints!
