waninkoko's cIOS (249 and 250)

This page is Outdated! Please use our new guide!

After getting the Trucha bug back into your system, you can then use that patched IOS to install a cIOS, which will allow most homebrew to run perfect, and allow backup games to be played via disc or USB. Waninkoko's cIOS was the first of it's own kind for while, so it can appropriately be viewed as the standard cIOS. His cIOS installs to the slots 249 & 250, so you'll notice you will more than likely use these IOS's when running homebrew or playing a backup disc.

<long_description>This is a Custom IOS, an IOS modified to add some new features

not available in the official IOS.

This IOS has been made to be used ONLY with homebrew software.

The Custom IOS installs as IOS249 and it does not modify any other IOS so it is secure to install.</long_description>
