WiiGater has released a new Nintendo Wii customization program named "cBoot2".
cBoot2 is a patched Boot2. You should be able to install a patched IOS if Bootmii is installed at boot2 location. You need to remove the GC memory card from slot 2 if you run this. Note: This package is only needed for people, who have updated without return and lost all downgrade capabilities. You will need a boot1 with a sign bug to use it. Purpose: Start patched IOS without installing using Bootmii loader. The original Bootmii doesn't support to modify the file system. With this package you get around this problem.
