The Sharp X68000 version of Super Mario Bros. is a way-to-play the NES game of the same name, released in Japan from unknown sources (maybe could be from a BBS). Rather than a port or a conversion, it is an unauthorized emulation, despite this version is just 100% identical to the NES version however.
Overview
This still the same as the NES version, however, color palette does not match the original game and the sound emulation is not 100% accurate, as this can be heard from the Noise channel. This is all the NES emulator's fault for the X68000.
This game relies on a joystick for X68000 for controlling Mario most of the time, while the Opt. 1 and Opt. 2 keys on X68000 keyboard serves asSelect and Start respectively. Since the X68000 use thes Atari standard of controller ports, either MSX, Sega Master System or Sega Mega Drive controllers could be used.
Trivia
- Aside from the emulator and the autorun files, the disk of the game has the original NES ROM included, but it are not in iNES File Format: They have both CHR and PRG ROMs separated, and a extra DAT file, with unknown use.
- A lot of earlier Famicom games, such as Wrecking Crew, Balloon Fight and Bomberman also received the same treatment, by using a simple, but satisfactory in terms of accuracy, NES emulator to run small NES games. Some of them has people credited somewhere on the disk files ,however.
