A major breakthrough has hit the Wii scene in the form of a program called Trucha Signer. This program allows you to modify the contents of a Wii iso and then re-sign it with an electronic signature the Wii will accept. Basically, in theory you could put anything you wanted into a Wii iso (or take out, eg: Wii updates) Possibilities are endless, somebody already made a gore mode ISO for Manhunt others are working on adding blood back into the PAL version of No More Heroes:
