What is Wii Brick Blocker ?
It is a little program which allows to patch an ISO file of a Wii game before to burn it.
A Wii DVD comprises 3 partitions (1 heading, 1 partition containing the update and 1 partition containing the game himself).
The WBB modifies the partition containing the update in order to replace it by a partition without update.
For that you have just to choose the file to patch, to click on the button patcher and to await 30 sec. That's it !
Engrave your game and insert it in your Wii without fear. Indeed, no update will launch out and you will be able to play your import game.
