I just forgot root, ok it ran, but critical rom2_path 'notset' not found. While I set roms 1 as /media/mmc1/games/nes roms 2 as /media/mmc1/games/nsf, and it calls me to use save botton to save. but it has no save botton, except I enter from fceu-gui>config. and even I use config to set rompath2, then close, save, back to main memu, nothing changed, no roms was found. Only the rompath1 is useable
