Wii stuck updating Adult chatters
The system, when it detects a newer version for an IOS, will prompt the user to start a system update.
The revision of an installed c IOS is thus usually maxed out to prevent the system from overriding it with a non-functional official version. It allows you to load things like virtual console games from a fake NAND (the internal memory of the console).
The steps essentially pre-download some required files which are otherwise downloaded by the console itself. As stated above, the configurations of this guide are recommendations based on various tests by the community. But you are free to install different c IOSs in different slots.
We only recommend to do this if our configurations don't work, though.
This fake NAND (often called Emu NAND, Emulated NAND) is stored on the SD card rather than the console itself.
