Final Fantasy I Randomizer vs Randovania

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.

Randovania is a free, open-source randomizer for supported games on Windows, macOS, and Linux. It rearranges weapons, keys, and other items among locations, and can also change area connections, travel requirements, starting equipment, and starting location. Its randomization aims to keep games completable without glitches or exploits. Multiworld can distribute items among several games and players, including a session played alone, and the project lists integrations for the Prime games, Cave Story, Metroid Dread, AM2R, and Samus Returns. Multiworld requires a Discord account. There are no hard limits on players or worlds, but sessions above 30 have seen little testing. When disconnected from its server, Randovania retains collected-item information and sends it after reconnection, including after a restart. It only supports unmodified game files; Prime and Prime 2 require uncompressed GameCube ISO files. The Metroid Prime page specifies a GameCube ISO and either a modded Wii or Dolphin Emulator. Larger Multiworld sessions can be discussed with the community on Discord.
