Issues with dark soft multi cps1

[rester159]

I’m having issues loading pretty much all games with the exception of ghouls n ghosts which works great. Final fight is audio only. Cadillac and dinosaurs shows the opening screen and then nothing. Others only show black screen.
Any clue?

Sounds like an issue with your C board. What model are you using?

 

[rester159]

how do I find out?

Well you need an unmodified c board with a b21 chip.

Provide a picture of your C board.

Could also be the replacement PAL that needs to be installed on the A board hasn't been installed or incorrect ROM set is being used
