Correct me if I'm wrong, but from what I'm reading you literally just need an SD Card to use this thing right?

And what of BootMii? Does it truly make the Wii Brick-Proof like a PSP CFW would?

(That is, its restorable after a Wii System Update fudges it up should it occur?)

On that note... what of games of that need higher firmwares.. are there workarounds?

This seems like a golden opportunity that flew over my head
