Application for importing and transferring Pokémon between save files
OpenHome uses Tauri, React, Radix UI, and Vite.
OpenHome is an open source, cross-platform tool for storing and moving Pokémon between games nearly losslessly, much like Pokémon Home on the Nintendo Switch. Unlike Pokémon Home, OpenHome also allows for moving Pokémon to past generations from future ones. When a Pokémon is moved into a save file, its data from other games is saved locally, so nothing is lost when transferring to past generations.
For example, you can move your Kalos Champion Sceptile from Pokémon X to Pokémon Ruby, earn the Artist Ribbon, and it will have both the Kalos Champion and Artist ribbons when moved back to Pokémon X.

All official PKM formats are supported, except for:
Colosseum/XD and Korean Gen 1/Gen 2 save files are also unsupported as of now.
Support for more formats will be added if there is demand for them, and when I have time to work on them.
PKM and save files for the following ROM hacks are supported:
Forms exclusive to these ROM hacks can be moved into OpenHome and save files of other ROM hacks that support those forms. This includes forms like Stitched Gengar, Balloon Pikachu, and Seviian forms. Support for these forms is new and may have some bugs.
When moving Pokémon to an older game, some compromises have to be made. OpenHome will try its best to preserve aspects of a Pokémon such as its nature, ability, gender, and
