[Rejuvenation V13] Save Editing - Export/Import Boxes?

[RustyMongoose]

Not sure if this has been tackled already, but I wanted to try my hand at save editing for Rejuv. Particularly, seeing if I can copy any of the Pokémon I collect in a new save over to my primary save. If I spend another 50 hours replaying the game and exploring different dialogue options and story branches, I want to be able to carry over what I get onto my main playthrough. But the blocks of text where each Pokémon's data is stored (in the Game.rxdata file + it's backups) are all kind of garbled messes full of broken symbols, almost like an encryption. I know there used to be a mod that made Box 35 be shared across save files, but that isn't supported for V13. Anyone know a better way to edit the files manually, or of a replacement for the Shared PC mod?

 

I know in Debug mode, you can create a Mystery Gift out of Pokémon in your party. There's no place to actually redeem the gifts, but it still generates text strings that contain all the info for the gift. That might be useful, somehow.
