Trying to make a simple change to my Fire Red .sav file

[boozie]

Hi, super new to this so I'm not sure about possible things I'm doing wrong, but essentially I just wanted to add Bite to my Wartortle because I messed up and didn't grab it at 18 when I'm guessing I was prompted and skipped.  I load the .sav in PKHeX, make the change, export to .sav, put it back on the SD card and then when I load the game up it says it's corrupted and loads a game from my previous save.

It started as 128 kb and finished as 128 kb.  Anyone able to help?  Are there other manual steps I'm not aware of?

You're going top have to be more specific. What kind of setup are you using to play. flash cart on ds or gba, 3ds with twl menu, 3ds with spoofed gba vc cia.

I might be having some similar issue to @boozie, so I'm gonna follow this topic to see how it progresses.
