Well, cIOSCorp full install is not necessary.
All you need to make it a simple install is:
PreLoader0.29
CIOS60BF.WAD (Not for Wiis LU64+)
PreLoader0.29 again to fix the Currupted Files Message.
Disc Channel Loading is now available, but, games will not load.
There is many ways to make this happen, but My favorite is to Take your *.iso in your computer and using IOSPatcher1.1a, patch it to use IOS249, and now all will load fine.
Regards.
