I forgot about that. i well is there any risk to formating a wii with homebrew a few CIOS's and bootmii
No, but you'll need to:
* resync wiimotes
* reinstall the HBC through bannerbomb & Hackmii Installer
* reset the wireless (and all other) settings
* restore the Backup disc dump
* install all your custom channels again
* redownload VC/WW that were purchased
* optionally reinstall the system menu theme
Bootmii and cIOSes will be unaffected.
Since I know you have DarkWii, it'd be a good idea to install a regular System Menu 4.1 before doing it. DarkWii+Format = ? (brick???)
