Zupapa!
A NEO-GEO action game designed by Face Corporation. It was shown at the AOU Exposition in Japan on February 22nd, 1994 right alongside Gururin. However, for some odd reason only Gururin was released back then. The game has cute comical characters and colorful playfields. It plays very similar to Capcom's Snow Brothers. It was dusted-off and picked up by SNK for release on MVS format in 2001. So far, this is the only Neo-Geo un-released proto game that finally saw an actual official release.

This game is strikingly similar to Nightmare in the Dark (released) and Bang Bang Busters (unreleased). Recent speculation suggests that its' sudden "out of the blue" release may have actually been pre-empted. We haven't all the details yet, but it appears that it shares much in common with the Shock Troopers 2 home cartridge release. The most significant thing about this game is that it serves as the Rosetta Stone for deciphering the NEO-GEO game code list. About 33% of what we know is because of this game!
