Well there's a modded gamma that runs off of IOS232.
Apparently Waninoko started with IOS37 and saw that IOS36 was more compatible for his patches. The only way to really know is to test every game possible on CIOS37 Gamma.
I do believe that wad installing still works with CIOS37 unless you install the Korean disc support version. Now if someone was to patch the Korean disc support CIOS it may be possible to add Wad support to it.
I am by no way an expert at IOS's but I do try to keep up with the releases. (Always cheering when the great hacking teams find a way around Nintendo's updates.)
Also I'd like to thank WiiPower for his multi-Cios installer made it a breeze to install CIOS37.
