PokeSim plays your own Pokémon Red, Blue, Yellow, Gold, Silver or Crystal ROM. Add it to its slot in Settings, then come back to create an adventure.

Game cartridges
One slot for each game. Drop a ROM file on any slot, or choose Upload. PokeSim recognises the game from the file itself and puts it in the right slot.
Clean English ROMs only, as .gb, .gbc or a ZIP holding one. Your ROMs stay in this application, and every adventure keeps its own save.
Pokémon artwork
Loading artwork settings…
Portraits come from your own ROM. Optionally install the community pack, one download that covers every supported game: Red, Blue, Yellow, Gold, Silver and Crystal. Each adventure then shows the artwork of its own version.
Optional download from PokéAPI. Pokémon artwork remains copyrighted. Source notice
Item artwork
Loading artwork settings…
Add small item icons to Stats → Items. TM and HM discs use the move’s type color, alongside the number and move name.
Optional later-generation icons from PokéAPI, stored locally for offline use. Pokémon artwork remains copyrighted. Source notice
Pokémon nicknames
Make the nickname pool your own with extra words, full names, and fewer unwanted defaults.
Backups
Save the whole library, or load an adventure from an earlier backup as a separate copy.
Creating a backup briefly stops running adventures to save their progress.
Import
Choose a PokeSim export or supported legacy adventure archive. Existing adventures keep their identities and saves.
Close PokeSim
Closing this browser tab keeps adventures running. Save and quit stops all adventures and closes the application.
