Hey everyone, Hope your weekend will be great.
I've got an NBA jam board that seems to work but when I insert coins the graphics go nuts. basically, all the graphics appear on screen at once, see the pics. Here's the run down.
A) When I start the game up it does a rom check and everything checks out (see pic 1), although it says something like CMOS OK in green and "USING DIPSWITCH COINAGE"
B) then a screen pops up that looks like a tv with static on it (pic 2).
C) The game starts up after I push a button and shows a demo before I insert coins (pic 3).
D) After I insert the coin, the graphics go nuts and I can't start a game (pic 4)
Any thoughts? Is it just that I need to adjust the dipswitches?
