cIOSCORP
It's a complete software modification for your Nintendo Wii to allow you to play almost all of your (original or backup) Wii and GameCube games directly from the Disc Channel without having to use a softmod loader application (like Softchip).


How to install?
Unpack the contents of this .zip file to your SD card and run the "cIOSCORP v3.4 Main Installer" application via the Homebrew Channel, sit back, and wait a few minutes. Do not stop the installation.
Do not uninstall anything before installing cIOSCORP: cIOSCORP v3.4 overwrites the majority of the system files (IOS) on your Nintendo Wii with modified ones.
That's it!
By the way a NAND backup before installing cIOSCORP is recommended

If you want to load backup GameCube games too, then run the "cIOSCORP v3.4 Extras Installer" application via the Homebrew Channel, and install EITHER WiiGator's OR waninkoko's cmios. Only one can be installed at a time, but you can change your mind by overwriting the one installed by installing the one you want.

How risky is it to install?
cIOSCORP v3.4 overwrites the majority of the system files (IOS) on your Nintendo Wii with modified ones which "know" how to handle DVD±R discs, so the installation process itself can be quite risky. You should be fine if you just let the installer run though.

cIOSCORP COMES WITH ABSOLUTELY NO WARRANTY, NIETHER EXPRESS NOR IMPLIED. THIS (AS WITH ANY OTHER MODIFICATION) WILL ALSO VIOD ANY OFFICIAL NINTENDO WARRANTY THAT YOU MAY HAVE. EVERYONE INVOLVED IS NOT HELD RESPONSIBLE FOR ANY DAMAGE THIS MAY CAUSE TO YOUR NINTENDO WII CONSOLE! YOU USE THIS AT YOUR OWN RISK!
