Are you refering to IOS's, try DOP-Mii.
So a little while ago, I found this Wii app that would show all of the available cIOS's, and even gave a little info about what game/s each one was made for. You could use it to download and switch cIOS's directly from your wii.
It was a great program, but I lost my SD card and now I can't remember what it was called! I've googled everything I can think of, and come up empty handed.
That's it, thanks!
