Open your Gen7 save file, enable the setting, drop in the pk9, fix any issues, then clone it and import until you find a satisfactory value after HOME migrates it.
If the Trainer Info editor has badges editable, sure, but really, you should just play the game as intended. Usually, Pokémon with your OT will always obey you.
Invalid save file format, completely wrong size. I was able to rip out some PK6 files though (3 party, 41 from box). Should match what you mentioned (Treecko, Mightyena, and Pikachu-Rockstar are present).

As has been stated multiple times throughout this thread, this program is only built for specific ROMs that have not been adjusted. You're trying to use the Vanilla BB2/VW2 version on "redux" which is a different ROM build.

Same weird corruption as someone else in another thread, where 0x1F bytes of data gets misplaced in the box data somehow, causing a big misalignment. Should be 99.9999% good to go.
It's nonsense randomness. Open a valid save file in a hex editor and scroll through it, and do the same for yours. Even without knowing what it should be, you'll be able to tell that the data is not what it should be.
