In case you guys haven't been in GBATemp's Wii Hacking forum, here are some important things to know:
1) NSMB comes with a new protection scheme. It's been broken, but it requires a new version of your favorite loader or manually patching main.dol, trucha signing it, and running it against a trucha-vulnerable IOS (which these days means patching the IOS to be vulnerable).
2) It's currently not possible to load this game via disc on a pure softmod setup. Modchip users can use a disc in conjunction with a loader, and USB loaders work, but not disc loaders.
3) As a suggestion, the game is only about 400MB when scrubbed. If you need to play a backup of it, go dig up that 512MB USB Flash Drive you never use any more and go the USB Loader route.
So can anyone point me to latest tutorials to run using a USB stick? What to do etc? No idea where to start. Searched and found lots of old info back in January and September but can't find a decent tutorial that is bang up to date.
