Here's some information I can provide. This is still a problem in the latest package from sid. 2.0.2.
However, I have two 64 bit machines, and they both do not exhibit this problem. The one that does exhibit this problem has a few more usb devices plugged in than the other one. But even when I plug more usb input devices into the laptop with a working sdl-input, it still works, and no matter what I try, the machine that does not work, will not recognize these gamepads even though I can use them in programs that do not use the sdl gamepad input system. http://www.emutalk.net/threads/55000-Mupen64Plus-does-not-detect-SDL-Joystick Perhaps this is a system configuration issue or a conflict with other packages. It doesn't seem like any other distribution has this issue, but that doesn't mean that they don't. To the OP, out of curiosity, does your machine in question use an xorg.conf file?
