[TUTO] WBFS Manager en 2026 : gérer ses jeux Wii sur PC avec TinyWiiBackupManager (Windows, Mac, Linux)

WBFS Manager and Wii Backup Manager are no longer updated: in 2026, TinyWiiBackupManager is what manages your Wii and GameCube games on PC, Mac and Linux.


Which software to choose in 2026
  • TinyWiiBackupManager (TWBM, version 6.1.5 from 10 October 2026): the successor, open-source and free, recommended by the reference guide wii.hacks.guide. It runs on Windows (from XP to 11), macOS 10.12 and later, and Linux (AppImage or Flathub), without Wine.
  • Wii Backup Manager (build 78): the reference for ten years, Windows only, and no longer developed since the early 2010s. Its official site has disappeared: it can only be found on mirror sites now, so be careful.
  • WBFS Manager (3.0.1): forget it. It only handles WBFS partitions, which are no longer recommended today, and its site (CodePlex) closed in 2017.

1. Preparing the hard drive

The reference guide is clear: format the drive as FAT32, partition table MBR, with clusters of 32 KB. Use neither exFAT nor WBFS; NTFS can work with USB Loader GX, but not with most homebrews, including Nintendont. An external hard drive or SSD is recommended rather than a USB stick.
Wii games are stored like this: wbfs/Game name [ID]/ID.wbfs. A game larger than 4 GB is split into ID.wbfs and ID.wbf1, because of the FAT32 limit. GameCube games, on the other hand, go into games/ for Nintendont.


2. Adding your games with TinyWiiBackupManager
  1. Download TWBM from its GitHub page, in the version for your system. On Mac, the application is not notarized: run once xattr -rd com.apple.quarantine /Applications/TinyWiiBackupManager.app in the Terminal. On Linux, make the AppImage executable (chmod +x).
  2. Connect the drive, click the drive icon at the bottom left and choose the root of the drive (for example E:\), not the wbfs.
  3. Click + (or drag your files): TWBM accepts.iso,.wbfs and.rvz files, converts them, splits them if needed and puts them in the right folder, Wii or GameCube.
  4. Eject the drive properly before connecting it to the Wii.
TWBM can also remove the update partition to save space, check game integrity, download covers and the wiitdb.xml database from GameTDB, and manage cheat codes and homebrews.


3. Your own discs, with CleanRip

The games must come from your discs, copied on the Wii with CleanRip. On a FAT32 stick, the copy is split into pieces (.part0.iso,.part1.iso); TWBM can reassemble them. By hand: copy /b *.part?.iso game.iso on Windows. Then compare the checksum with the one in the text file created by CleanRip.


On Linux and Mac, from the command line

The Wiimm’s ISO Tools (wit, version 3.05a) do everything from the command line, on Linux, Mac and Windows. For example, wit copy --wbfs game.iso --DEST folder creates a.wbfs file split at 4 GB. Be careful, wit convert replaces and deletes the original file. The old Witgui (Mac) and WBFS Manager under Wine are no longer needed.


The most common errors
  • The game does not appear in USB Loader GX: folder without the ID in square brackets, or.iso dropped in by hand. Run the name normalization function in the TWBM toolbox.
  • “i/o error” in TWBM, on Windows: run it as administrator.
  • A GameCube game does not start after a conversion with an old version of TWBM (before 4.3.2): normalize the paths once.
  • WBFS Manager does not see the drive: it only reads WBFS partitions. Back up your games, then reformat the drive as FAT32.
To launch your games on the Wii, see Wii: playing your games from a USB hard drive, WiiFlow Lite, and for the GameCube, Nintendont.
