Would it work to change the path for scummvm extra path from /usr/share/scummvm to /recalbox/share/scummvm rather to enable users saving extra data files (read, MT-32 emulation roms for better audio) ? (Screenshot path is already pointing to /recalbox/share/screenshots)
Also, would is work for pathing to put --path=\"$dirname\/\"$filenameNoExt"" instead of --path=\"$dirname\" so you could drop all .scummvm files into /roms/scummvm folder and have the games launched at single press, rather than traversing into scummvm/gameid and then launching?
