I found this board labeled as Buccaneer for cheap and picked it up, wasn't really sure what it would be. It turns out it's a Pac-Man hack. It's in Misfit already (some version that used different sized roms) but now it's proven to have been sold to arcades instead of a recentish hack so it can be added to the official. I think the bootleggers started with a copy of the Pac-Man (Hearts) bootleg and then went crazy on it.
