#1 need help with button mapping

[Anonymous]

Any progress on custom key mapping? Seems like a pretty big deal to leave out... You see, I've got a USB N64 controller that works great BUT I can't map the keys to it as the box is grayed out in CuteMupen. The D-Pad is not assignable in wxMupen64Plus (all other keys work though) AND key maps default back to keyboard inputs on M64Py... So none of the Mupen64Plus front ends actually work for me! Please find attached: a screen shot of the problem. Also, here is a URL to the product page of the controller I'm using [ http://stoneagegamer.com/pcmacusbn64controller.aspx ]
Finally, below is SDLJoyTest output info:
