Controler config problem

[sawdigger]

I have been using my n64 controlers with project 64 and its been working perfectly except there is 1 button on both my controlers which seem to be ignored whenever try to config them, the yellow down button. Everything else works just fine and i have no clue why that one button doesnt get registered/noticed whenever i try to keybind it. It works fine when i do it on different computers so idk what the deal is. Any advice would be greatly apreciated.

Hey there, what plugin are you using for controllers? If you are using the default Jabo's Direct Input, I would recommend using NRage's Input Plugin. Btw, what adapter are you using?
