What is it?

PokoHex is a save editor for Pokopia, a Pokemon-related game, that works on save data dumped from the Nintendo Switch 2. Users supply their own save file; the program does not extract saves from the console itself.

The project is available as a Windows x64 build distributed through GitHub Releases, and as a browser version hosted on GitHub Pages that runs on any platform. It is styled after NHSE, a well-known save editor for Animal Crossing: New Horizons.

The maintainers explicitly do not support cheating at other players' expense. The project recommends keeping console save backups before editing or restoring any save file.
