This utility will move, rename, and delete files on the target SD card in order to conform to MODE's requirements, including single-folder multi-disc support. Please do not run this program against a copy of your daily-use GDEMU SD card. Instead, use a copy or backup.

    ,
      
    03
    , etc.) renamed based on

  • To take advantage of MODE's automatic disc-queueing abilities, multi-disc games are grouped in the same folder with all of their files renamed for proper alphanumeric sorting.

    GDEMU.ini
     configuration file automatically deleted.
  • If no
