Zupapa!
An action game by Face. 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.
