Okay, so this has been a long road of trial and error. I've been trying to play 2 player VS. battles on my PkmnXD:GoD game on my gamecube (refurbished), but every step of the way something goes wrong.
At 1st everything worked fine and dandy, but then suddenly, no matter what controller i plugged into the second player's socket, it wouldn't respond.
Then, once i cleaned up the GC and the controllers, it still wouldn't work. i cleaned the sockets with 50% iso(..something to do with Alcohol) on a cotton swab, then against my better judgment, blew into the socket (there was alot of dust <.<). Still nothing.
I then did some more digging online and tried the X+Y+START trick and that seemed to make it respond! but once i played through a mock battle to test things out, i discovered that the Down Directional Button wouldn't work no matter how hard i pushed it down (edit: its not "stuck", the game just doesn't respond when the button is pushed)
TL;DR: the down directional pad button won't work even after cleaning. any suggestions on what i should do?
here's a pic of the controller, as you can see it's not an official model (got it from GameStop i think)
