'''Released: 23rd October 2008''' - '''Found in games'''
* This blocks '''new installations''' of anything fakesigned, that is, [[Homebrew Channel]] beta 8 and below (beta 9 contains a workaround), unofficial wads (legal and illegal), [[Starfall]]/[[Preloader]], cIOS
, [[BootMii]], anything that installs IOSes secretly like [[AnyRegion Changer]] or [[AnyTitle Deleter]], [[xyzzy]] and [http://hackmii.com/2008/08/libdi-and-the-dvdx-installer/ DVDX] (used for apps which have DVD support; the latest version contains a workaround). This list is not exhaustive, but please add to it if you think of anything else.
* This also blocks access to /dev/flash in all [[IOS]]es but [[IOS30]], [[IOS31]] and [[IOS37]]. This means raw nand dumping utilities, for example [[Yet Another Wii NAND Dumper]], no longer work, since by default homebrew uses [[IOS35]]
* '''If something is already installed then it isn't affected, like [[Homebrew Channel]], etc.'''
