If you get the message "no roms found", your configuration should be okay. If you have zipped roms that are not supported by gngeo, you will also get a "no roms found". As I always ask to check things on the command prompt first, so please try this in the x-terminal: Code: /opt/gngeo/bin/gngeo --scandir /home/user/MyDocs/emu-roms/neogeo/ If it does not show any games but the zipped roms are in this directory, your zipped roms are not supported and you should find other versions of them.
/opt/gngeo/bin/gngeo --scandir /home/user/MyDocs/emu-roms/neogeo/
