Open 2 windows of PKHeX, one load SS save, another load UM save, then drag the one from SS save into UM. Just use encounter database to inject them. Else play the save (before you encountered the legendary) in the mirror version. For that, I recommend you change your TID, SID, and OT, to prevent any same OT details but different game recognition in PKHeX and HOME. Lastly, don’t ask for help in an unrelated topic. I’ve split your post out.

That’s cool information. Where would the 128-byte RSA signature be located at if it wasn’t removed?

Probably couldn’t be validated by the devs in any capacity thus not included

And how do you know they are legit? You have the cert/letter that accompanied them? You received them yourself with events of the photo?

Yes, the odd egg data isn’t stored in the save

How was the save transferred to the Switch? SD card? FTP?

Is he using Emunand? That sounds an issue with using Emunand. Just boot CFW into SysMMC and restore the save there.

Yeah the lightyears metric affects what wormhole spawns as you're flying. Once you're in it doesn't really matter any more. I personally use the program HxD to hex edit any data.

The lightyears metric doesn't affect legendaries/UBs, as far as I am aware, so I'll move on to non-legends. For non-legends, their shininess is already determined upon entering the world, so even if you could affect it the lightyear metric (which again, AFAIK isn't stored), wouldn't matter cause shininess was already determined. It means that the encounter was already decided to be shiny or not shiny. As long as you're in that world, even if you reset the game, the shininess of the encounter is already decided. Read here: https://projectpokemon.org/home/forums/topic/39433-sm-usum-save-research-thread/page/3/#comment-239090 So edit the byte in a hex editor, load the save into PKHeX to fix checksums, then export the save. Then import into your game.

You referring to the string of text that shows up after you’ve entered a wormhole into a different place? What do you need it for? It’s a temporary value not saved in the save (as far as I know) and wont have any bearings on what you’re gonna encounter (as you’ve already entered the world…)

What’s a bun save file. You playing some kind of ROM hack?

If you make it too illegal, it may not enter HOME, even as first time entry. otherwise, legal edits then first time entry into HOME (from the correct game) shouldn’t be a problem. That is where it gets it’s HOME tracker. Once assigned a HOME tracker, you shouldn’t make any modifications. And if you do, do not touch the immutables.

Legal, not legitimate. Also it won’t be assigned a HOME tracker until it can enter HOME (eggs can’t enter HOME), so the important part is whatever stats it has after it enters, has to remain. Keep in mind it can have illegal stats as it enters, and the act of being able to enter won’t make it legal nor legitimate

No ETA; it’s not just Pokémon stuff I deal with, I have life to deal with as well. Just look at how long it took me to update non-shiny entries for HOME

Potentially illegal entries got mixed in. I’m working on fixing issues, such as common OT/ID between game versions and what not. Would take a while to deep clean them.
