stump's Pokémon Red/Blue Key Item Randomizer

Things to be aware of

Randomize a ROM


Provide a ROM image of English Pokémon Red or Blue. Support for other versions may be added later. ROMs that have already been randomized with the Universal Pokémon Randomizer will work too.


Enter a number from 1 to 4294967295. Enter 0 or leave blank to get a random seed.

No ROM images are hosted or stored on this server.

This randomizer is free and open source software.

Please send any questions and feedback (including bug reports) to stump's Discord or the project issue tracker.
