YouTube - New Mario Bros Wii 2 - THE NEXT LEVELS
Someone already beat you to it and released it and fully playable on usb loader...
This game is simply AWESOME!
90% New Levels, Hard as Hell!
Took me a couple tries to beat Level 1 World 1 !!!!
Can't wait for more of these CUSTOM LEVEL EDITED games to surface.
Also there is a Kustom Mario Kart Wii out too!
