Punch Ball Mario Bros.

Punch Ball Mario Bros. is a game created by Hudson Soft for the PC-8801 in 1984. It also ran on the PC-6001mkII, NEC PC-6601, FM-7, and Sharp X1. It is very similar to Mario Bros., but with a new feature named "punch balls" that could be thrown to stun enemies as an alternative to hitting them from below, as in the original. Once stunned, the hit enemy could be hit like normal. The details of the licensing of this game aren't clear, but Punch Ball Mario Bros. is probably one of the earliest licensed Mario games. It is unknown why Hudson Soft was permitted the rights to and chose to make the game. Hudson also produced two other Mario games for the PC's: Mario Bros. Special and Super Mario Bros. Special.

Like in the original, Mario and Luigi starred in the game. Common enemies from the original also appeared, such as Shellcreepers and Sidestepper. Unlike the original, the floor-level design is almost the exact opposite of the original Mario Bros. For instance, the first platform (above the floor) in the original extends from the edges, with a gap in the middle. In this game, the platform is in the middle, with gaps around the edges.
