Hmmm.. you shouldn't be able to post here.. never mind.. it's true, System Menu 3.5 came out in Korea.
http://wiibrew.org/wiki/System_Menu_3.5Version 3.5 of the System Menu was announced on March 3, 2009, by Nintendo sending notices to the Wii Message Board. (Korean Region Only As Of This Posting)
Update appears to include IOS52 (used by menu) and IOS254 (a copy of IOS9, to block PatchMii). Along with Updates to all 4X IOS versions (IOS40 IOS41 IOS43 IOS45 IOS46)
Seems like Twilight Hack beta2 still works.. IOS4X are Korea IOS files (they most likely updated all of them with signature fixed versions).. additionally it updated the shop which most likely already happened on EU/NA/JP Wiis with 3.3v2 - so the update contains old news for us.. most likely we won't see it besides it doesn't block homebrew any better than the current!
