I use my Nintendo Controller to play SRB2 for a while, and I haven't ran into any problems with it till recently. The joystick (L and R) don't work now, so I go to my settings and I see everything is set up properly. I go to different versions of the game, and still does not work. I even swap controllers and still nothing works right. I'm trying to find a way to stop this issue, and also contact the devs.
Update: It now drifts when I'm not even touching the joystick. This update for the game sucks.
Update 2: Nevermind my joysticks were broken. I take back what I said about the current update.
