Swiss usage may vary. It can do a lot of things so the aim is to cover the more complex features here.


Booting Swiss


Launch the DOL file provided in the download archive. Generally you can use the compressed version, but if this fails, try the uncompressed DOL.

Viper GC Extreme Flash

There's issues when trying to launch the normal builds of Swiss via the Viper GC Extreme flash so please use the special Viper DOL provided.

Installing Swiss to the Wiikey Fusion Flash

Swiss can be installed onto the Wiikey Fusion flash to act as the main boot menu.


It is recommended to only use this if you're booting GameCube games as the file system Swiss supports is FAT32 (4GB file limit so Wii games won't work). The author holds no responsibility for any bricked Wiikey Fusions (although the recovery disc should be able to fix just about everything!).


Stock firmware

0. Update to the official 1.5 firmware first, and set region override to true.

1. Place the "SwissFlasher.gcm" bootable ISO for your region onto the WBFS formatted SD card using WBFS Manager 4.0.

2. Boot this "Swiss" ISO up on your GameCube.

3. This will boot up a custom version of Swiss and it should present you with a directory as seen in the picture below.


4. Enter the directory and select the FZN file (USE PAL only, yes, even if your console is NTSC/etc, the others are broken), click on the file and follow the prompts to flash Swiss onto the Wiikey Fusion.


5. Once complete, remember you will need to use a FAT32 formatted SD(HC) card with your wiikey fusion!

Already running Swiss

0. Extract the PAL FZN file from inside SwissFlasher.gcm (it's just an ISO, so browse it using something like ISOBuster)

1. Put the FZN file and the latest Swiss DOL on your SD(HC) card and insert it into your Wiikey Fusion

2. Boot up the new Swiss DOL on your Wiikey Fusion by running it in Swiss (which was booted from the Wiikey Fusion)

3. Select the FZN file and click load - follow the prompts to flash it.

Alternate Procedure

1. Extract the .FZN file from the SwissFlasher.gcm (open it with an ISO browser) and load it in Swiss from a compatible storage device.

USBGecko as a storage device

Run SwissServer.exe on your PC in the directory you want to serve to your GameCube/Wii. Start Swiss and select USBGecko. Make sure that printing debug over USBGecko is disabled in swiss settings first. SwissServer can be compiled for linux too.

Booting Games

Games can be booted via nearly every storage device, simply put the ISO on a device such as the SDGecko or the original or a backup of the disc in the drive and select it in Swiss.



The format of the cheats is GCT - which is the format developed for the Ocarina cheat engine. There is also support to use .QCH (Cheat DB for Qoob), but there is no guarantee that these cheats will be translated properly for the Ocarina engine to utilize them.



In order for cheats to be auto-loaded, GCT files must be named the exact same as the ISO/GCM with a .gct extension after them. For example: Metroid Prime.iso Metroid Prime.iso.gct

Manual Loading

If you want to load a .GCT or .QCH, you can click on it in the file explorer and load it up prior to selecting your game.
