If you tell me the exact layout you want, I'll do it for you. Or You have to navigate to /home/user/.mupen64plus Find the blight_input.conf and edit each button with a code from here http://www.asciitable.com/ (Ensure that you only use the lower case ones) Example "R Trig-key( 117 )" is u on the keyboard If you want to change it to be p on the keyboard, change the "117" into "112" as it corresponds with the p on the table above R Trig-key( 112 )
