Spec score 7.6 #9 of 24 in Game Randomizer Tools

What it is

Final Fantasy I Randomizer is a free browser tool for changing the original US 8-bit NES Final Fantasy game. Upload a compatible ROM, choose a seed and flags, then generate a randomized ROM file or spoiler log. Settings can move key item locations, towns, and dungeons, and change monster and fiend difficulty. Presets include Improved Vanilla, intended to make the original game more welcoming to new players, as well as Floor and Entrance Shuffle, Shard Hunt, Chaos Rush, and Chaos Rampage. More detailed options cover maps, treasures, shops, enemies, party, classes, gear, and other gameplay areas; cosmetic choices include music, palettes, sprites, and interface behavior. Users can save presets, export them to JSON, and load them later. The browser interface runs locally without an installation, but playing the output requires a NES ROM and an emulator or compatible device. The randomizer works only with the US ROM version. Its maker recommends using a legally owned ROM and does not provide a download link. A seed can be recreated when the version and flags match, except for cosmetic Fun% settings.
