While Wizardry 5 was the only scenario we North Americans received on the SNES, more than half the series was translated to that platform in Japan. Wizardry 5, Wizardry 6, and a compilation of the first three scenarios in one cartridge, were all ported and released by the Japanese company ASCII.ASCII also created several original Wizardry scenarios not based on any of the PC games. The first three games in this so-called "Wizardry Gaiden" series were released on the Gameboy, and the fourth on the SNES. I have played ROMs of all four Gaidens--in case anyone is wondering, I read Japanese fluently.
Wizardry Gaiden 1 to 3 (the Gameboy ones) are similar to Wizardry 5 in gameplay (e.g. ranged weapons and the "Hide/Ambush" command exist). The SNES Wizardry Gaiden 4 is quite a bit more interesting. While the game system is basically Wizardry 5's, the BCF/CDS races and classes have been incorporated into the game, with totally new spells for the Alchemy and Psionics users. Moreover, the whole game has an Oriental flavour--the title sequence tells the game's story against a background of traditional-Japanese-looking paintings; the dungeons resemble Eastern castles; and the monsters include Japanese ghosts, Oni of all shapes and sizes, and even an Orochi. Wizardry Gaiden 4, subtitled "Throb of the Demon's Heart", is a Wizardry scenario like no other.
I have also tried the SNES version of Wizardry 6. In addition to the obvious graphic/sound enhancements, it features a title sequence which tells the background story of the game (basically the story from the instruction manual, translated into Japanese); a built-in character portrait editor (although the included character portraits are already very nice, with a much better balance of races/genders than the PC version); and yes, an automapper. However, it also has some limitations: there are only three savegame positions, no difficulty selection (it's permanently set to EXPERT, more or less) and NPC interaction is limited due to the lack of a keyboard.
