Installing the GC Loader in the Nintendo GameCube

The GC Loader is an optical drive emulator (ODE) for the Nintendo GameCube. It replaces the optical drive with an SD card reader and works together with Swiss — the most widely used homebrew loader for the GameCube. No more fragile mini-DVDs, no laser issues, the full library on one SD card.

GC Loader PNP vs other versions

The GC Loader PNP (Plug and Play) connects directly to the IDE connector of the optical drive — no soldering required. This is the recommended version for most people.

Step 1 — Open the GameCube

Remove the 4 GameBits screws on the bottom (the large ones with the special head)
Lift the top of the housing off
Remove the fan cover (held by clips)
Remove the fan (disconnect the connector)
Remove the 3 Torx T8 screws holding the optical drive

Step 2 — Remove the optical drive

Disconnect the IDE flat cable from the optical drive (press the lock and slide out)
Disconnect the power cable
Lift the optical drive out of the GameCube

Keep the drive safe — it’s a valuable spare part.

Step 3 — Install the GC Loader

Connect the IDE flat cable to the GC Loader
Connect the power cable
Mount the GC Loader on the mounting points with the included screws
Insert an SD card with Swiss onto the GC Loader

Step 4 — Put Swiss on the SD card

Download the latest version of Swiss from the official GitHub page
Format the SD card as FAT32
Copy swiss.dol to the root of the SD card
Copy your game ISOs into a folder (e.g. /games/) — use .iso files

Note: SD card format

The GC Loader works best with FAT32-formatted SD cards. For cards larger than 32GB you'll need an additional tool for FAT32 formatting (Windows defaults to exFAT for large cards). Use guiformat.exe or a similar tool for larger cards.

Step 5 — Test and close up

Don’t fully close the GameCube before testing
Connect power and turn on the GameCube
Swiss loads automatically and displays your games
Select a game and test that it starts correctly
If everything works: reattach the fan, cover and screws

Done

Your GameCube now loads games directly from an SD card via Swiss. Load times are comparable to or faster than the original optical drive. Via Swiss you can also adjust settings, enable cheats and use diagnostic tools.
