only if they both have the same user profile (also a Nintendo Switch feature to share user profiles locally), both at the latest firmware, both has access to the internet and can use Nintendo server features (no DNS blocking of any kind)

So far all the poke_trade I’ve seen are rather small, hence can’t store enough enough data to be significant. (I’m assuming it doesn’t grow). I’ve read about it storing trade info too, but I don’t know the particulars. All the ones I’ve seen so far have been the same. If they are indeed different, perhaps they store data like what mon you’ve most recently put up for link trade or surprise trade or something. That’s just a guess. In any case, it should be safe to move on with whatever you’ve been doing. Edit: So my 2022 poke_trade is exactly the same as my 2020 poke_trade, and I definitely made some trades. Until definitely proven otherwise, I'm just gonna make a calculated guess and say that the 'it stores trade data' is something people assumed based on the name on the file, with no real backing behind it.

I can’t recall if CIAs specifically has that check (I think they do) but it won’t matter if you’re running the CIA in CFW. CFW by default bypasses that check.

To be specific, those carts do run a check to see if the region of the 3DS matches the printed (manufactured in) region on the cart, yes. But that’s pretty much before the game properly runs. Initial phase, much like giving the prompt to older consoles to update their firmware. Once the game runs, the save uses the 3DS’ region and stores it, NOT using the cart’s manufactured region. Hope that clears it up. In other words, you can’t use a different region’d cart to try to bypass the Vivillon locality issue. Like I said earlier, it’s based on the coordinates saved into the 3DS’ profile, the cart has no influence over it.

The region info is stored on the 3DS, not the cart. A proper Pokémon CIA should run on any 3DS region’d device. Anyhow, when it comes to spoofing Vivillon forms (ignoring save editing to change the form) there’s no way around it: you gotta CTRtransfer to properly have the 3DS be in another region.

It’s based on how the 3DS works, and how the Pokémon game piggybacks off that function. When one selects the sub-region and country on a 3DS device the normal way [country settings], the device actually stores a set of coordinates (based on the location) in the 3DS profile. It appears to be normally not used nor seen, however the Pokémon area of the save reserved for Vivillon actually grabs and uses that area the moment you start a new game. The game determines which Vivillon encounter you should have based on those coordinates. People couldn’t tell there’s a difference (hidden cords, not region settings), because when you set the country settings in the device, it changes the coords to reflect that. Everyone wasn’t using CFW so there would never be a coord-country mismatch like you’re experiencing now. The Luma region spoofing correctly sets the region and country settings, but doesn’t touch that pair of secret coordinates. That pair only correctly shows up if you use the in-device menu to set the country settings. Thus, if you really really want to spoof Vivillon, consider doing a CTRtransfer for region spoofing. The 3DS CFW guide should have the CTRtransfer files there, and GBAtemp should have an old guide on using that to region spoof. I recommend doing that on a copy of your Emunand. All at your own risk tho. PKHeX doesn’t create a database of OT/TID/SID and cross check if all the region data to see if they’re consistent. The legality checks are more “this Pokémon is isolated in a bubble away from real world details” kind of thing. Anyone from the real world who took a look would know something is amiss. Anyhow, the form is set the moment you encountered the Scatterbug/Spewpa/Vivillon. The game doesn’t set the form upon evolution; it’s already there. It’s just that you only see it in game at the final evolution. In an isolated bubble world sense, probably fine.

Where are your game saves at. Try searching the Desmume app folder for .dsv files

People have been using Sysbots on CFW devices to trade mons 24/7 for years and those aren’t instabanned. it’s about not having piracy, nor other stupid nonsense on your Switch. Anyhow, all at your own risk

Maybe it’s not decompressed, hence why it’s not showing the 0A properly

The encounter data is correlated, so you can’t change the stats if you don’t know what you’re doing.

Not A0, 0A. Refer to the original picture of mine, should only be 2 spaces behind. Hmm, does the values to search exist again in the hex?

Step 3f of Extracting ExeFS. instead of copying the bin, go into the folder that is 2 entries above it.

If I’m not mistaken GodMode9 should allow you to decompress ExeFS by allowing you to enter it like a folder, then copy paste the code.bin you could give that a try in the mean time. I’ll take a look in my free time when I get around to it.

It is possible to have a mon that belongs to you be traded before. Doesn't have to be traded with the bot.

If you only change the level of the Pokemon you own it would still be legal. (I guess the only issue would be whether the game imposes limits on whether the mon would obey you) Alternatively you could just hack in a bunch of max revives and potions.

How bout just only use legal Pokémon?

If the game forces it into an egg, then no. It is game enforced behaviour; PKHeX is a sav editor, can't edit the game. Maybe try making your mons less illegal. (or just not illegal at all).

So you were talking about Sword. Sword hasn't had a version update recently. Also, unused moves and species show up fine in Sword; for unused species, the Pokemon model will show up as Pikachu but the summary shows up there. In any case, it sounds like you did any other update. You should update the mon here, but in any case it sounds like a error on your part regardless. You should not expect to illegal mons to work properly in-game.

I sincerely this isn't an issue, and it is very likely you misremembered the edit you did last time. But yes, there is a major update to Legend Arceus somewhat recently, so there's a chance that changed, but I largely doubt it is that. What edit did you do?
