Put Rollergames back together after a full shop, touch up and clear coat.
I have some weird things going on, but the first and foremost is the display.
Looks like this. I have reseated all the cables and double checked their placement.
I agree. Definitely seems like a ribbon cable placement issue. I have double and triple checked cables and found errors in placement.
The OP says the are "other weird things going on"... I would like to hear what those are.
Aside from double checking the ribbon cables, I notice the game EPROMs have no sticker over them... its a longshot, but perhaps a little sunshine spoiled some data locations on a chip or two.
