Ok, I finally was able to remap keys (by installing Filebox and accessing the gngeo folder), but the screen size stays the same no matter how I change; scale 2 (don't use anything on ur gpx2) and scale 2x (on effects part), also on screen 320 true/false. I uninstalled xgngeo and am trying to uninstall gngeo on app manager to start again, but it says unable to uninstall 'gngeo' , then App Man close with a error 'Internal Error App Manager closed'. I tried on X-term 'root' , then 'apt-get remove gngeo' then 'y' hitted enter... It starts, then says 'dpkg: error processing gngeo (--remove) failed to delete media/mmc1/roms.dpkg-tmp read only file system Errors were encountered while processing: gngeo E: Subprocess usr/bin/dpkg returned an error code (1) . Can anyone help?
