About the Game

This is an unauthorized Sega Mega Drive hack of Squirrel King, known under the titles Super Mario World and Super Mario Bros.; its developer and publisher are unknown. Chip and Dale are replaced by Mario and Luigi, while the first two acts use levels modeled on Super Mario Bros. and The Lost Levels and end with Bowser. The remaining acts retain Squirrel King's gameplay, so pipes and blocks in the Mario-themed stages are nonfunctional.
