Even if it's not finished nor perfect yet, the ideas behind it and the Implementation are great. I was looking for EoS hacks for a long time because I love what was doable for the mainline games. This right here is exactly the kind of romhack EoS needs to be the best version of itself and I hope it gets even better Great Work, keep it up.
Awesome
A button for max all IVs and reset all EVs could save a little more time instead of edit one by one
Just go to click on max IVs then Reset Evs and edit the few ones that you require
Thanks for all
Author edit: Already in the program, control click either button for the desired functionality. For more shortcuts, see Options->About PKHeX->Shortcuts
The hack is very well done, but unfortunately I find it a bit too difficult and unfortunately there is only the option to save via the emulator. Unfortunately, the message Save failed appears in the game
