DK64 Randomizer vs Universal Pokémon Randomizer FVX

DK64 Randomizer is a free, open-source tool for changing Donkey Kong 64. It can randomize items, loading zones and locations, alter game length and difficulty, set custom win conditions, and provide a plandomizer and hint system. Built-in logic is intended to keep generated seeds beatable and every item reachable. The web generator can create a new seed, use a patch file, or regenerate a past seed. Options include spoiler logs, password locks, advanced ROM headers and delayed spoiler-log release. Compatibility is limited to the US NTSC-U release; NTSC-J and PAL releases are incompatible, and the project requires a legally obtained US ROM. Listed play options include most Nintendo 64 flashcarts, Wii U Virtual Console injects and various emulators. Local use requires Python 3.11 or newer, while console use needs a flash cart or a homebrewed Wii U for Virtual Console. A Discord server provides community support.

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.
