Help Needed: PKHeX Reads My Pokémon White .sav File as HGSS

[Sh3en]

Hello everyone, I’m having an issue with my Pokémon White .sav file. While I can load the save and play the game without any problems using the Melon emulator, I’m unable to view or edit my Pokémon through PKHeX. When I try to open the file in PKHeX, it reads it as if it’s a .sav file from HeartGold or SoulSilver (HGSS) instead of Pokémon White. Any help would be appreciated!

PKHeX finds a valid HGSS footer in the second save file (0x40000), which is somewhat true as evident by the box data containing PK4 data (not PK5 data).

Use a hex editor and zero out the byte at 0x4F620. That will invalidate the build timestamp for the HGSS save, and PKHeX will then recognize the save data as White.

You likely imported your HGSS data into the emulator and restarted it, which doesn't actually clear out that incorrect save data file. Thus, the old save data lingered in the unmanaged area and is causing your issue.

THANKKK YOUUUU! Zeroing out the byte at 0x4F620 worked perfectly—PKHeX now recognizes the save, and I can edit my Pokémon!

Really appreciate your guidance. Thanks again!
