I am new to Linux based systems and recently just received my Raspberry Pi that I have been trying to turn into a retro arcade system. I have been following http://supernintendopi.wordpress.com/ mostly as well as other sites and forums attempting to get my system up and running. I have gone through the entire process twice from installing the RetroPie image to transferring roms and configuring both the ES front end controls and the configs/all/retroarch.cfg file for the emulators. The ES front end controls work fine (I am using a USB SNES controller), but after two days of researching and messing with my retroarch.cfg file I cant seem to get it to work within the emulators. The only thing that works there is hotkey/exit button combination that I set up as start and select "8" and "9" respectively. I have been testing the controls mostly in the NES emulator on super Mario games but I have tried others as well and cant get it to work. I have tried the cd RetroPie/emulators/RetroArch/tools
./retroarch-joyconfig >> ~/RetroPie/configs/all/retroarch.cfg command line and it writes to the file. Also have edited it myself adding the hotkey and deleting the extra buttons.
Please someone offer me some advice so I can get this fixed, it is driving me crazy and consuming all my thoughts!
