I can not run GBA games

I upload some games to my Gameshell but it is not finding my files for any GBA games? Can anyone tell me how to do?

Can you show us the content of your action.config file?

ROM=/home/cpi/games/MGBA22
ROM_SO=/home/cpi/apps/emulators/mgba_libretro.so
EXT=gba,gbx,gb
LAUNCHER=retroarch -L
TITLE=MGBA Roms
SO_URL=http://buildbot.libretro.com/nightly/linux/armhf/latest/mgba_libretro.so.zip

What format are your GBA games in? You can add ‘zip’ to the EXT list…

Does it going to work? I am not sure.
