So Nintendont used to work just fine with my normal HID USB controller but that one died and now I'm trying to use my PS3 controller. First I tried the Nintendont app and that just kept glitching out the menu arrow thing, crashed when I got in-game or some times got in the game but the controller didn't work. So I downloaded the most recent build of USB Loader GX that supports Nintendont and it wasn't recognizing the HDD with the controller plugged in, so I plugged it off, and it went fine. Then I plugged in the controller again and started Melee, Nintendont screen showed up and it just reset the whole goddamn system. USB Loader GX is working fine with Wii games.
