just read bonaparts reply to pannkaksfest and that sorted the no rom error 1. Through x terminal if you type gpspmgui the application should start up then click back on to x terminal and see if it shows 'cant create cfg dir, permission error' 2. To fix it open up x terminal under root type:- mkdir -P /home/user/.config/Team16/gpsp/ then press enter 3. Then open up gpsp-gui and set up GUI config ( rom directory and copy bios) 4. Close gpsp then open up again and you should see your roms.
