thx boss and labontecar43.Yop thats the methode and worked like a charm
For all not so familial user i have made some screen shot´s how to replace the Channel.wad with WiiScrubber.First Trucha will not work becouse it can not handle more than 2 partition´s and MKW have 3 partition´s.SRY have forgot this
Than i use WiiScrubber v1.3 becouse v1.4 have some bugs for extracting / replacing files and so on.
You can use this with HardMod or SoftMod.If you have the cIOS60 on your sys than you do not need a Modchip.Just use my LCUD to boot the WAD Manager v1.3 from Wii OS and first install cIOSv9, than rebbot, do the procedure again but now install HBC.wad
If you have the cIOS249 on your sys it will be even better becouse just boot UUDv2 and install the HBC.wad.
And here for the HardMod methode:
Open your MKW.iso with WiiScrubber
Klick on "+" for Partitoin 3 - Installer.Right klick on the MKWChannel.wad and choice replace
Navigate to the HBC.wad and double klick it
At last just klick OK and your done
Burn to disc and install the Channel as showed in the Vid
