I appreciate all the work done on this website (my save file would still be corrupted without this site's help!) so i just want to make a shout out to the programmers on here.
I was wondering if it is possible to reset the event of receiving your national diploma in Heartgold (or previous generations, but Heartgold is the game I'm currently playing) using PKHeX. I can see that there are certain events that can be reset and edited, but I did not notice the diploma event. I tried to see if I could delete one Pokemon (Ratatta and Raticate specifically) from my box and Pokedex, and catch it again, but that didn't work. If anyone has insight into this particular manner I would appreciate the help!
