In regards to Super_Mario_Galaxy_ReadNFO_Wii-PROMiNENT:
A lot of people are asking the same questions, so hopefully this mass PM will clear things up.
Here are the known facts:
1) The release is real. It was ripped from a "kiosk" version of the game, which is believed to be the retail verson.
2) The release ONLY works with a D2Ckey modchip. Trying to boot the game using any other modchip will result in an error screen ("Error #001, unauthorized device has been detected"), while using BrickBlocker just gives a black screen.
3) The release contains an update. The update has something to do with modchip detection, though specifics are not known. It does NOT update your console to 3.1U. Installing the update is done at your own risk. Attempting the Metroid Prime 3 method of unplugging during updating on PAL consoles has resulted in at least one case of semi-bricking.
If you are interested, you are encouraged to participate in the various discussions on this topic (whether they be in the torrent comments, the forums, or the IRC channel), but please, do not ask questions that have been answered already. Thank you and good luck to us all.
