The main reason you shouldn't update to Wii System Menu 4.2 or 4.3 is that there is no actual update for anything, just annoying ways attempting to prevent Wii hacking.to re-install IOS60 (if you are on Wii Firmware 4.0 or 4.1) or IOS70 (if you are on Wii Firmware 4.2) or IOS80 (if you are on Wii Firmware 4.3) with the signature hash check (trucha bug).
This guide is targeted at people wit no hacks/mods on their Wii, so essentially a store-bought system.
However, this guide can still help people that have the Home Brew Channel already installed (simply do step 1 and then skip to step 5).
As mentioned, tried with three different providers already.
Updates Wii Shop Channel again (people with older firmware are unable to access it without updating theirs).
DVDx is an older method for playing DVD movies on your Wii.
It is no longer the recommended method, and so we don't feel you should install DVDx.
Adds Korean IOSs to E/J/U Wiis, and E/J/U IOSs to Korean Wiis.
This was done to prevent users from installing old versions of these IOSs, in order to exploit the fact that the function ES_Add Title Finish didn't check for signatures. Updates Wii Shop Channel again (people with older firmware are unable to access it without updating theirs).
However, I thought that since the red 25 th anniversary console was released in November, it would already have the latest September "hot fix" update on it.
Are there any other games that have the update, apart from Mario-All Stars?
Instead of updating your Wii firmware, you can just use DOP-Mii to update specific channels such as the Nintendo Channel or Wii Shop Channel (which also requires an IOS61 update) without updating the Wii Sytem Menu.
