It seems pretty apparent Nintendo doesn't want people messing around with their files and then resigning them to use if the latest system update tells us anything. The latest Wii Update will disable Freeloader and other "Trucha related" exploit methods in the future...at least temporarily as it includes a fixed signature-checking function.
When a title (game, channel, etc) starts, it tells the system menu (using a field in the TMD) what version of the IOS it needs to run on -- to support this, the Wii stores all previous firmware versions. (For most Wiis, this will be IOS9, IOS11, IOS13, IOS15, IOS17, IOS20, IOS21, IOS30, IOS31, IOS33, IOS34, IOS35, IOS36, and now IOS37).
As of March 22nd, no software uses IOS37 -- the System Menu currently uses IOS30. An updated System Menu will likely use the new IOS37.
What does this mean?
- Until the system menu is updated to use IOS37, it will have no effect.
- Once the system menu is updated to use IOS37, "Trucha-Signed" discs -- or channels -- will stop working, as will the Datel FreeLoader disc.
- At that point, "homebrew channels" would be considered "invalid" by the system. The consequences of this are unclear, but that could potentially prevent the Wii from booting.
- Other versions of IOS are not affected.
- The Twilight Hack is unaffected.
Note: To clarify, the current update does not disable the Trucha signed discs, nor disable the FreeLoader, but it does install the means of doing so (aka the function is currently not active.)
