I would like to thank those who help us out with server costs on Patreon. However, for several months this income has not met our server costs, so unfortunately we have to bring back ads to help pay for hosting. The specifics will be fine tuned over the next few days/weeks, but anyone who's an active patron will be exempt no matter what. If you are a patron and see ads while signed in, please send me a DM either on this site, on Patreon, or with the Contact Us form at the bottom of the page.

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 25.11.06 of PKHeX has been released, fine tuning support for Pokemon Legends: Z-A's, and adding other save editing functions. Do not report issues with this release's handling with legality/encounters.

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.
