Well, for people having problems with the bios just google neogeo bios, the first results should already help you, just unzip and go to the folder you unziped with the app itself, and you will be alright. It seems that gngeo only recognizes maemo neogeo roms, and not neoragex roms. ( read this on a gp2x forum, if anyone can confirm. ) For the executable, I still didn`t find the good solution, and the deb Kybo offered, I can't seem to install it, giving me error while setting ownership of media/mmc1/roms. If I can't get this to work, i will try compiling the emulator myself, as much of the work is already done anyway... Edit .: Well, solution to the mmc1 problem was simple, just open the backcover, it will umount the sdcard ( you can do that on xterm too ), and install it normally via xterm or app manager. Edit2.: Ok got it to work, will test and give feedback on any edition of files if needed or so.
