Nintendo licensed Hudson Soft to port some of Nintendo's Family Computer games, such as Golf, to home computers in Japan. Hudson Soft also created sequels to Mario Bros. called Mario Bros. Special and Punch Ball Mario Bros., a sequel to Donkey Kong 3 called Donkey Kong 3: Dai Gyakushū, and a unique Super Mario Bros. game for the computer, Super Mario Bros. Special. These games are not exclusive to the PC-8801 and can be found in other popular 8-bit home computers in Japan like the Sharp X1.
Mario games released for the NEC PC-88
Donkey Kong 3: Dai Gyakushū
Donkey Kong 3: Dai Gyakushū was released in August 1984. The game is not a straight port of Donkey Kong 3 but more of a semi-sequel. The game removes Stanley's ability to jump and the need to protect plants, making it much closer to something like Galaga.
Mario Bros. Special
Mario Bros. Special was released in August 1984. It is not a straight port of Mario Bros., but an original arcade-style platformer with adjustments to the graphics and sounds. There are four different screens. The stages involve Mario figuring out how to progress to the top of the screen, and some levels feature unstable platforms that shake if jumped on.
Punch Ball Mario Bros.
Punch Ball Mario Bros. was released in October 1984. It is very similar to Mario Bros., but with a new object named the Punch Balls that could now be thrown to stun enemies.
Unlike the original game, the floor-level design is almost the exact opposite of the original game. 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. Footholds are sturdier and do not trip the enemy if hit from underneath like the first game - only the Punch Balls or POW Blocks could do this now.
Super Mario Bros. Special
Super Mario Bros. Special was released in 1986. While superficially very similar to the original Super Mario Bros., the game features original new levels and lacks a screen-scrolling mechanism. When a player reaches the end of a screen, the screen turns blank and loads the next part of the level. Jumping and running physics also differ from the original, providing a much more challenging experience than Super Mario Bros.. Adding more difficulty is the fact that the timer of the level runs much faster than in the NES game, which was already much quicker than the timers in the latest Mario games. Returning was Mario's Hammer from Donkey Kong, alongside a variety of past foes and new exclusive items from the earliest arcade Mario titles, Mario Bros. & Donkey Kong.
Due to the PC88's technology being slightly inferior to that of the NES, the audio and graphics differ slightly from the original NES game as well, although replicated closely. Additionally, the game does not include Luigi or a multiplayer mode.
