Ocarina of Time Randomizer vs Universal Pokémon Randomizer FVX

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.

Universal Pokémon Randomizer FVX is a free, open-source desktop tool for changing data in vanilla core-series Pokémon games from Generations 1–7. It supports games for Game Boy, Game Boy Color, Game Boy Advance, Nintendo DS, and Nintendo 3DS, with Pokémon: Let’s Go, Pikachu! and Let’s Go, Eevee! excluded. Options cover Pokémon traits, evolutions, starters, moves, trainer and wild Pokémon, items, and type effectiveness. FVX adds palette randomization and custom player graphics, with support varying by generation: palettes are fully supported in Generations 1–3, partly supported in 4–5, and unavailable in 6–7; custom player graphics are limited to Generations 1–3. A seed and settings string can reproduce a randomization, and logs can be disabled to prevent spoilers during races. Users must provide their own ROM files. ROM hacks are not officially supported. For 3DS games, files must be decrypted; randomized output can be saved as CXI or LayeredFS. If a game update is loaded, LayeredFS is the only output option. The tool runs on Linux, macOS, and Windows.
