got a Pac-Man PCB that’s undergone numerous repairs to get it booting, now at a decent stage of progress but I’m wondering if anyone knows much about the sprite movement circuit.
all sprites are stuck on top of each other at a static point on the right hand side of the maze, like all the sprites are being written to the same memory address ?, already swapped out 1e,2e,1f & 2f which all tested faulty and this moved the sprites from the top of the maze to their current position.
any help greatly appreciate, I’ve found a post with the same issue from a few years ago but looks like they got stuck there too.
