use the CIOS uninstaller, or just format your wii......and welcome to the hardmod scene!
don't get rid of the HBC though, put that back on if you format...
you can take out all the channels you don't want (HBC is titleID HAXX), and you can remove cIOS's (such as 249 and whatnot... just don't remove any real IOS's!
either anytitledeleter or cios uninstaller is needed to remove CIOS's. Just be careful with anytitledeleter.
I have hard mod, but still keep gamma and softchip on reserve, just because they seem to get the error fixes down before the modchips improve their firmware. Even though I guess I could patch my games for error 002.
