Launch Gamecube homebrew on Wii. Read before using! Program can be dangerous, because the flash is changed.

DOL loader is patched into MIOS. If Wii switches to Gamecube mode, the DOL loader is always started. That means that a Gamecube disc can't be started. This behaviour can be disabled by reinstalling a normal MIOS. I don't have a Gamecube disc, so I don't have tested it.

1. Copy RVL-mios-v5.wad.out.wad into root of front SD card (This file is not part of the archive and is located on Super Mario Galaxy Disc (EU)). If you use a different version, this is on your own risk. The MIOS patching wad installer will only allow to install MIOS. This can only break the GC mode. If the patch fails, it could patch Starlet code. Starlet code has the ability to brick your Wii.

2. Patch MIOS using MIOSPatchingWADInstaller. CAUTION: You can't play any Gamecube Disc anymore!!!

3. Copy your Gamecube Homebrew DOL into SD root as start.dol. Use Wii Gamecube Slot A for SD Gecko.

4. Launch GCBooterHomebrew. This should start the the DOL on the SD card. If screen looks strange, you need to try it again. It is sometimes not working.
