Cannot play with gamecube controller

[injflea727]

So I've been playing this for a while and noticed that some of the buttons are off with my GameCube controller. A Is now the x button, and the L button controls both the crouch and the camera's zoom. With a modern controller, none of the buttons are mapped wrong. Can you add a dropdown menu to select which controller you're playing with? It's quite infuriating to try and speedrun this game with a GameCube/n64 controller as of right now.
