"They wrote a special-purpose function to try to check for the exact exploit we used — specifically, if a savegame is for Zelda, it checks the length of 6 strings inside the savefile (two of which are the player name and horse name)."June 16 Wii update
"It’s interesting to look at the timestamps here. The System Menu has a build marker of “systemmenu.rvl.0803060727″ – yes, that’s March 6, 2008, 07:27. This update to the menu only accomplished one thing, as far as I can tell — the blocking of the TP hack. (I guess we can count the IOS30 patch together with it.)
They spent 3 months testing it — this isn’t actually that surprising, when you consider the potential financial damage if they roll an update out that bricks Wiis.
Congrats to tmbinc and tehpola for finding a combination of two bugs in the code that Nintendo added that — when combined — allow us to fool their check into ignoring the TP hack. More info will be forthcoming — I still wouldn’t rush to update my system, anyway."
