Nero, it doesn't work anymore — it crashes. I'm still able to access the move relearner menu from the party screen, but after a while, it gives an error message, and I have to close both the message and the game using Alt+F4. Maybe it's because the game got a recent patch and the mod is now outdated? Also, I didn't see any option to edit IVs, EVs, or similar stuff.
also folder is patch(p lowercase) not Patch, and i created Mods folder inside patch folder
SOLVED: I think the nero_learnmenu.rb file in the top is not updated, so it just used the other file you posted as the update. It seems good now.
