Final Fantasy I Randomizer vs Ocarina of Time Randomizer

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.

Ocarina of Time Randomizer changes where items appear in The Legend of Zelda: Ocarina of Time, creating a different playthrough. Its logic is designed to make every seed completable without glitches and avoid softlocks, even with any possible dungeon-key use. Players can adjust item and entrance placement, pots, crates, cows, shop prices, songs, cosmetic settings, starting inventory, and damage settings. The web generator lets users choose options, generate a seed, and patch a ROM in the browser. Generating and playing a seed requires an Ocarina of Time 1.0 NTSC-U or NTSC-J ROM. The site recommends a multicore CPU, at least 1.5 GB of RAM, and an updated browser. Mobile patching is supported but slower; listed device support includes Android phones with 2 GB or more of RAM and iPhone 5 or newer running iOS 10. Offline builds are available for Windows, macOS, and Linux. The project is free and open source. Its site points users to racetime.gg for races and Discord for discussion and help.
