This board has had some repair work done on it before and not very well but I’m not too happy about messing with it just now so ill leave it alone.


Game has jailbars through all of the sprites both in game and in the title scenes.



First off, I put the board into test mode and let it run its maskrom tests. ROM H6 showed up as being bad.
These maskroms are compatible with 27c400 eproms. Removed the maskrom and burned a new eprom from MAME. Game now runs fine.
