GC backup launching has 3 requirements:
1. a cIOS is installed(of course)
2. a cMIOS is installed
Only way until now is a cMIOS installer, in the latest installer from WiiGator you have 2 options: 1. Select what will be installed(see below) and 2. what MIOS version to use as a base, don't know which one is the best, v4 or 5 is Action Replay compatible, the later ones might have some compatiblity fix(from nintendo! if retail works, it won't help backups)
3. a launcher
I really recommand using WiiGator's GC backup launcher as it has the best compatiblity and it works with both cMIOS install options. The other option is disc channel(with cioscorp or rebooter) or Gamma/NeoGamma and requires the bigger install of the cMIOS.
PS: The installation of a cMIOS might affect running of GC retail discs as it overwrites the MIOS.
