I've just been using citra and i've become really interested in playing pokemon y, i tried using citra but i can't find it anywhere in the game catalogue so i've been trying to find the rom elsewhere. I looked at the megathread and downloaded the internet archive version because Myrient shut down, but both the 3ds and the Cia version don't work. Can someone help me or tell me what i'm doing wrong? Am i supposed to get a different emulator or something?
