OK, this was literally exhausting. X(
I'm very thrilled to say that I've gotten all trades for Gens 1, 3 and 7 (Just USUM atm)! Gen 2 is here and Japanese Blue is here for anyone that didn't see them.
Things I need to point out:
For G1
I wasn't able to get the Japanese codes for unused trades working, so I just re-created the ones from the glitch video, hope that's alright.
Japanese Stadium Pokemon were re-created based on INT Stadium .pk1s.
For G3
Feel free to change any of the RS and FRLG trades Pokemon's origin game detail to their polar-opposite, with the exception of the Nidos as they're version-exclusive.
The XD Elekid all are based on the Togepi trade; you can just click around the Pokemon's moveset box's border in PKHeX still in G3 format to give them the Togetic trade's moveset.
For G7
Both Chinese languages share the same trades; ones I've claimed have CHS tags.
Feel free to change the origin game to Ultra Sun if you wish.
@theSLAYER One again, feel free to use them to your liking. Same goes for anyone else.
With that being said, I'm gonna be taking a break from this, very tired rn. The list of all languages for trades are (apparently) known, and looking into the Gen IV trades, those HGSS Gym Leader trades are gonna be very tedious to get, but the worst I can feel are definitely the Yancy/Curtis trades. x_x
