[ROM Hack] Gengar Evolution in Neo Y

I am currently playing Pokemon Neo Y, I read the altered evolution requirements which says level 36 for haunter to evolve, I have my haunter currently at level 42 (raised from gastly at level 15). How can I make it evolve? Am I missing something? Help or suggestion will be much appreciated! I really want a mega gengar in my roster

Hi,

Travel Journals is the place to write about your runs in Pokémon games. If you have questions about a rom hack, I suggest asking in Neo X and Neo Y's own thread at ROM Hacks Studio.
