I got a Bubble Bobble board that powers up and can run test mode, but in game mode I get a flashing "I/O Error" on the screen.
I built my own jamma adapter for this and so far I have only hooked up the power wires and the video output wires, there are no controls or sound hooked up. So that limits the problem down to something on board the pcb.
I saw another thread on here about this problem but it seemed to dead end, just curious if anyone else was able to fix this error.
Thanks!
