No.

AMS = Atmosphere SXOS = Team Xecuter's SX OS

And did you add the TR moves?

Legality checks updated. PKHeX checks are not definite, and are always subject to change. That being said, PKHeX's checks are far more intensive than what the game/Home/etc has. The Pokemon are by definition illegal, but that probably won't stop you from bringing them to Home.

If the Nature is a not a neutral nature the only neutral nature it can have as a Stat Nature is Serious. There's no Hardy Mint. Basically, if the Pokemon has (Nature = StatNature = Neutral), that's fine. But if it's (Nature != Neutral, StatNature = Neutral - Serious), then it's illegal.

Updated.

Just the Pokedex, as the option suggests.

Can you let us know what was the last action you did before receiving this error?

With the update of Pokemon SWSH v1.2, save file sizes have increased. The new save file size is 1575705 bytes, but we have seen some save files which are 1575632 bytes. The first release (literally few minutes in) of the latest update of PKHeX didn't account for this, but PKHeX was quickly patched to account for the "dwarfed" save size. If you are unable to load the save with a 1575632-sized save, redownload PKHeX. What we want to know is why there are two different save file sizes. The current working theory is that there are two upgrade paths: v1.0 -> v1.1 -> v1.2 would yield 1575705 bytes, while v1.0 -> v1.2 would yield 1575632 bytes. Quite possibly, we would see this for users with both games, with one as their main (e.g. I play Sword but have Shield for completion reasons, and have not played Shield since v1.0). If you have a save file that is 1575632 bytes in size, please help us confirm this theory by letting us know if you went from a v1.0 save to a v1.2 save (save was last used in v1.0, never saved in v1.1, game updated straight to v1.2 and saved).

Bad dump, file size is too small.

1575632 should be supported. Try redownloading PKHeX and placing it in another directory, then opening from there.

Load a v1.2 save.
