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 was similar to Mario Bros., but added "punch balls" that could be thrown to knockout enemies. 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.

Interestingly, 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.
