How risky is it to install?
cIOSCORP v3.5 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.
How to install it:
Unpack the contents of this .zip file to your SD card and run the
"cIOSCORP v3.5 Main Installer" application via the Homebrew Channel,
sit back, and wait a few minutes. That's it!
All System Menu IOS (11, 20, 30, 40, 50, 52, 60, and 70), along with
IOSes 35, 36, and 37, now all have the ES_Identify Patch in them.
This allows preloader compatibility, and should allow the majority
of homebrew applications to use the ES_Identify function, but due
to the way the newer IOS work, it will only allow ES_Identify to be
called once per IOS Reload.
How to uninstall it:
Fisrt of all, DON'T DELETE ANY IOS!!! YOU WILL (most likely) KILL
YOUR WII IF YOU DO!!! Rather, the IOS must be OVERWRITTEN with
official, unmodified IOS. Just download the cIOSCORP v3.5 Uninstall
package, copy it to your SD Card, and run the uninstaller via the
A compatibility list has also been included in the package. Open the
"cIOSCORP_v3.5_compatibility.html" file in your favourite web browser.
