I just picked up one of these boards yesterday, although mine is hacked to run Ms Pac-Man (it has a small satellite board above the ROM's for the extra ones required by Ms Pac, and some extra jumper wires running around the board

) It plugged right into my Crazy Kong machine but the screen is upside down (CK is upside down compared to alot of games). The player 2 controls didn't work though, but I may need to check where I put the ground wire on the harness for player 2 side when I rewired it. I also have a Phoenix bootleg (which is also Falcon pinout) that also doesn't work on player 2 side, although CK does.
BTW: That maze is usually referred to as Hangly Man, although I assume Falcon must have included it on their bootleg. It said "bonus puckman at 10000" instead of "bonus hangly at 10000".
