Also, if you see roms loading progress bars but return to the GP2X menu after the convert tile progress bar,
you probably have an incomplete BIOS. You should have the following files: 000-lo.lo, aes-bios, asia-s3.rom,
neodebug.bin, sfix.sfx, sm1.sm1, sp1.jipan.1024, sp-e.sp1, sp-j2.rom, sp-s2.sp1, sp-s.sp1, uni-bios.12,
usa_2slt.bin, vs-bios.rom, neo-geo.rom, ng-lo.rom, ng-sfix.rom, ng-sm1.rom in GnGeo2X's rom directory for a
complete bios and for GnGeo2X to work.
