[TUTO] Sauvegardes Wii et GameCube en 2026 : SaveGame Manager GX, GCMM, Nintendont et Dolphin

Copying a protected save, backing up your GameCube memory card, moving your progress from the Wii to Dolphin: the right tools and the right folders in 2026.


The Wii Menu, and its limits

The Wii Settings > Data Management > Save Data > Wii menu copies a save to the SD card. But some publishers block copying, others only allow it partially, and you can only copy a save back to the console if there is none for that game. The Wii mini has no SD card slot.


SaveGame Manager GX: copy every Wii save

SaveGame Manager GX (r127), on the Homebrew Channel or the Open Shop Channel, also copies the saves the menu refuses, as well as Miis.
  1. First make a NAND backup with BootMii: the tool writes to the console's memory.
  2. It requiresIOS58, present on any up-to-date Wii.
  3. To restore a save, a save for the game must already exist on the Wii: launch the game once first.

GCMM: the GameCube memory card

GCMM (GameCube Memory Manager, version 1.5.2) copies saves from your memory cards to the SD card (folder MCBACKUP), and back again. Copy the gcmm folder into apps/ on the SD card.
  • Formats: .gci (one save) and .raw (the whole card).
  • With the Wii Remote: 1 to back up everything, B + Minus to copy the whole card, B + Plus to restore it. With the GameCube controller: R, L + Y and L + X.
  • A.raw copy can only be restored to the same card. Only insert or remove cards from the main menu.

Nintendont: where the saves are

Nintendont emulates the memory card on the SD card or USB drive, in the saves/ folder: one file per game, named after the game's ID (GALE.raw for Smash Bros. Melee), or a single ninmem.raw file in “Multi” mode. A card copied with GCMM (.raw) can be renamed this way and placed in saves/. Avoid cards larger than 251 blocks, which cause problems.


Moving your saves from the Wii to Dolphin, and back
  • Wii to Dolphin: copy the save to SD from the Wii, then in Dolphin, Tools > Import Wii Save (file data.bin).
  • Dolphin to Wii: Tools > Export All Wii Saves creates private/wii/title/…/data.bin; copy the private folder to the root of the SD card, then import it through the Wii Menu or SaveGame Manager GX.
  • GameCube: Dolphin's Memory Card Manager imports and exports.gci files. Launch the game once before importing.

The most common errors
  • “This save data cannot be copied”: copying blocked by the publisher; use SaveGame Manager GX.
  • Restoring fails: a save already exists (Wii Menu) or does not exist yet (SaveGame Manager GX).
  • A save from another region: it is generally not recognized by your version of the game.
Before doing anything, a BootMii NAND backup remains the best insurance: see ModMii and Nintendont.
