There have been many Wii System Updates for the Wii. Listed here are the ones that in some way affect homebrew.

Updates

System Menu 3.4, added IOS50 and dummy IOS254 (just IOS9), updates IOSs 30, 31 and 37

Released: 18th November 2008

  • Blocks the installation of the Twilight Hack version 0.1beta1. Twilight Hack version 0.1beta2 (because of its not being version 0.1beta1) can still be installed for long enough to install HBC.
  • This version of the System Menu uses IOS50.
  • Does not appear to affect custom channels (although there have been unreliable reports to the contrary)
  • Breaks PatchMii by installing a dummy IOS (IOS9) into the IOS254 slot (pointless, expect the next attempt to be slightly more effective)
  • Adds the dev/flash/ blocks to IOSs 30, 31, and 37

IOS51 & Updated all IOSes except IOS30, IOS31 and IOS37 (these were already partialy updated, see below)

Released: 23rd October 2008

  • 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, cIOS, BootMii, anything that installs IOSes secretly like AnyRegion Changer or AnyTitle Deleter, xyzzy and DVDX (used for apps which have DVD support). 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 IOSes 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.
  • The Shop Channel backend was also updated at this time. You need the new Shop Channel (first available with this update) to access the Wii Shop Channel, but this can now be worked around with Wii Shop and IOS51 installer.
  • If you already have the Homebrew Channel and DVDX, and aren't planning to install anything big that will affect your Wii, then you are most likely unaffected. Normal everyday apps such as Homebrew Browser are completely unaffected as long as you already have the Homebrew Channel.
  • It updates all IOSes with the fakesigning bug, and adds IOS51.

System Menu 3.3 & Updated IOS30 and IOS31

Released: 16th June 2008

This update blocked old versions of the Twilight Hack. The newest version contains a workaround, and retains compatibility with all Wii firmware versions. IOS30 and IOS31 have fixes for the Signing bug backported from IOS37. Since the System Menu uses IOS30, fake-signed discs have been blocked.

IOS37

Released: 21st March 2008

This iteration of IOS contained a fixed signature checking routine--a fix for the Signing bug. Although installed on many Wiis, IOS37 has not been found active in any way that would disable any hacks.

Other Updates

Need For Speed Undercover requires an update to play, and ticket installation for the Twilight hack beta2/ Homebrew Channel fails when you try it. Not fully understood. In other words, can no longer install homebrew channel.
