PKHeX is a save editor for core-series Pokémon games. With it, users can manipulate various save files including: .sav, .dsv, .dat, .gci, .raw, and .bin types. PKHeX can also read and write: .pk files, which are individual Pokémon files, and .pgt, .pcd, .pgf, .wc, wcfull, which are Mystery Gift files.
Version 25.08.30 of PKHeX has been released, featuring faster legality checks, various fixes, and backend improvements.
PKHeX now requires the .NET Desktop Runtime 9.0 to run. If you receive an error when trying to run, ensure you have it installed.
Please note that other related applications will still require time to update, and updated versions of plugins or SysBot may not be available immediately.
