  • 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 25.02.23 of PKHeX has been released, featuring numerous fixes, improvements, and quality of life enhancements for legality checking.

    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.

    • Legality:
      • Added: Handling for new HOME gifts (Meltan, Keldeo, Manaphy, Enamorus).
      • Added: Gen7b Received DateTime validation. This was missed for how many years? Use the batch editor to fix any affected.
      • Added: Gen1 recognition for Japanese tour Mews. Thanks @ShadowMario3 !
      • Added: Separated word filter for NDS, 3DS, and Switch contexts. Thanks @abcboy101 !
      • Added: Gen3 encounters now show nearest initial seeds and frame counts elapsed.
      • Added: Gen4 Pokewalker IV spreads are now validated and show initial seeds.
      • Added: Current PP verifier. This is a naive check to highlight box mons that haven't been healed since capture. Will be improved in future.
    • Added: Gen1 Hall of Fame editor.
    • Added: Gen3 Hall of Fame editor.
    • Added: Gen3 Secret Base editor. Thanks @pasqualenardiello !
    • Fixed: Gen7b encounters now generate with a valid Received DateTime.
    • Fixed: Gen6 Link data now saves correctly. Thanks @R-YaTian !
    • Changed: Gen3 RSBox now shows boxes similar to visual row order in-game rather than by order in the save file.
    • Changed: Sprite generating performance improved (less allocation).
    • Changed: Encounter template generating loops have been improved to better seek input criteria (IVs, nature, etc).

    Seems like there is a problem with the cosmetics. Or am I doing something wrong?

    Why do they have 3 PP Ups for each move but not the right amount of PP for each move?

    To check legality within a box slot, hold control when right clicking the slot for the context menu.

    Hello everyone, I’ve recently been playing Pokémon X on my 3DS with a version of the game that enhances the difficulty for a better experience. However, this version does not modify the data of the Pokémon you can catch or obtain, as it focuses on difficulty and preserving the legality of captured Pokémon.

    I’m using the latest version of PKHeX, and I see several symbols. As far as I understand, the warning symbol means that a Pokémon is not legal, but all the ones I’ve caught have the legality checkmark. However, there’s also a small warning symbol next to each Pokémon.

    Could someone help me understand what this means?

    Hi there, this may be a release-related bug/feature (could be either tbh) or just coincidence.

    I replace a lot of batteries on Gen III games and always make a habit of dumping the save (Joey Jr) and verifying checksums prior. I have now seen two games out of the last 5 I've serviced on the new version that is giving me the "Final extra data invalid." checksum error. Was not able to uncover much on this after a basic search.

    Games load, play, and edit fine. Opening the game inside PKHeX and saving a copy of the save corrects the error in the new file. So very much a non-issue, but still curious. I have NOT taken a look at these in a hex editor yet...

    Attached are the two saves (both Emerald); can you enlighten me on what this is?

    Hi, Catch Meowscarada from recent Event, and PKHeX says its illegal Pokemon. As I understand, this is because of absence of Meowscarada in Encounter Database of PKHeX?

    It says my Eevee is illegal, but I gave it 108 pokéblocks (4*nutpea berry)
    138 + 152 + 124 + 118 + 116 + 108 = 648 
    648/6 = 108

    When I try to download the MGDB, I get an endless message, and when I press legalize active pokemon, it tells me that the plugin version is obsolete even though it's the LATEST DAMN VERSION. Does anyone know what the problem is?

    This isn't the place to report issues with a plugin. Seek assistance where you obtained the plugin from.

    • Since they released over a decade ago, the Pokémon Mystery Dungeon games for the Nintendo DS have not had much in the way of ROM editors. Over the past few years, hackers have slowly learned more and more about the inner workings of the games, culminating in the most advanced PMD editor to date: Sky Temple. 

      SkyTemple is a user-friendly level editor for Pokémon Mystery Dungeon: Explorers of Sky that gives the user full control over graphics, scripts, Pokémon data, and more, enabling a great amount of creative freedom to prospective ROM hackers to create not just edits of the game, but entirely new levels and plots.

      See the trailer for the version 1.0.0 release for quick samples of what can be accomplished:
