Hello all, is there a way to adjust prof oak's script using xse to have the national pokedex completed at 250? I'm doing a hack that only focuses on gens 1 and 2.
And once completed, can I insert a trainer battle with prof oak? (I've already made a battle with him a separate encounter, just wanted to give a bit more of a reward than wroooaaaaarrr!!
