Trouble is the modchip manufacturers haven't really released a wrokaround to the new backup protection routine that NSMB and the yet to be released games have.
A number of different tutorials already exist for NSMB, some softmod and some hardmod. If you are just using a drivekey I would suggest focusing your efforts in learning how the hardmodders run it. Otherwise it needs to be loading from USB, which imo is easier, better and safer.
What we at Wiihacks are trying to avoid is thousands of NSMB threads which just dilute the impact the great Guides have.
