GC yeah but... get yourself a HDD and and use that for Wii games atleastmuch quicker load times ect ect...
As far as I know there is no Multi Wii game loader, to be honest the best way is via HDD, that NeoGamma can also handle just fine (I am a lil behind on whats out there though)
http://gbatemp.net/topic/160300-wii-...creator-v354f/ guess what that is for
I guess it is worth trying a copy a few ISO images onto a Data disc and seeing if NeoGamma can read those... can't hurt just a waste of DVD (or read up more on NeoGamma)
