Here's something you don't see everyday, this is a prototype Gang Hunter arcade game circuit board from Seibu from 1988. This boardset was obtained from a distributor who made trips to Japan in the late 80s and obtained it directly from programmers at Seibu. The game was later released as Dead Angle in the US, we're not sure it was ever released as Gang Hunter. We were told the game was finished or close to that, it does appear playable.
This particular board has a gun daughterboard for light gun controls (joysticks don't respond). Boardset is tested and working fine, although we didn't connect a gun to see if those controls work. See pictures for more details on its exact condition, board is in good condition, pretty clean.
