There have been many Wii System Updates for the Wii. Listed here are the ones that in some way affect homebrew. <noinclude> ==Updates== </noinclude> === [[System Menu 3.4]], added [[IOS50]] and dummy [[IOS254]] (just [[IOS9]]), updated IOSs [[IOS30|30]], [[IOS31|31]] and [[IOS37|37]], [[bc]] and [[mios]], updated [[Mii Channel]]. === '''Released: 18th November 2008''' '''Found in games''' * 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 [[IOS30|30]], [[IOS31|31]], and [[IOS37|37]] <!-- correct me if I'm wrong --> === [[IOS51]] & Updated all [[IOS]]es except [[IOS30]], [[IOS31]] and [[IOS37]] (these were already partialy updated, see below), added some IOSes that were only previously available from Wii Discs, updated [[Wii Shop Channel]]. === '''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.''' * 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 [http://hackmii.com/2008/08/libdi-and-the-dvdx-installer/ 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 [[IOS]]es with the fakesigning bug, and adds [[IOS51]]. === [[System Menu 3.3]] & Updated [[IOS30]] and [[IOS31]], updated [[bc]] and [[mios]], updated [[Mii Channel]]. === '''Released: 16th June 2008''' '''Found in games''' 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''' '''Found in games''' 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 === Currently, no other updates, older or newer than these, affect homebrew. See [[System Menu Versions]] for more info on other updates.
