I've been updating little by little, so I'll try to get to it soon.
Just a little note if you are using DeSmuMe.
Although PkHeX can open .dsv, it only saves as .sav
So after you edit your save file, all you have to do open the game in DeSmuMe and go to "file">"Import Backup Memory", then select the edited .sav file.
Nevermind, PkHeX can save as .dsv, so the striked out part can be ignored.
Also, make sure the hacked Tympole fits the rules of the challenge (so basically as if you just caught/hatched it, no egg moves, no max IVs/EVs, etc.).
