The update partition for [[Title database#00010000 and 00010004 : Disc-based games|''Animal Crossing: City Folk'' (RUUE)]] contains [[IOS History|IOS38]], which may be required for the game's WiiSpeak feature. But it also contains [[System Menu 3.3]] and a "fixed" IOS30 and IOS31, which disables things that depend on the [[signing bug]].
And Disc Channel won't let you start ACCF until you've installed all updates from the partition.
Here's how to '''install the new IOS''' so that ACCF will work:
#Move IOS38-64-v###.wad from the root into the <tt>wad</tt> folder.
#Use WAD-Manager to install IOS38 to your Wii console.
Use [[Gecko OS]] instead of Disc Channel to start ACCF.
