Ninja Baseball Batman graphics problem

Post by Moosebag »

So I have a baseball batman board that's just started to develop graphics issues.

It seems to be character and item sprites only, game and sound is fine. Characters are there, the game recognises them but they're just flashing occasionally and disappearing.

I'll just show it in this video for clarification.

I believe it's an original board and not a conversion.

Irem m92 board.

I don't really know anything about repairing boards and don't k ow where to start looking!?

Board looks ok visually, where should I be looking for an error like this?

Any help is appreciated

Hi Jon,

Do you see the J3 jumper in this picture?

Try re-seating that. I've had sprites disappear on these M92 boards - that fixed it for me.
