you can't he just pwned himself

That's why the update is included on disc, if your Wii is not updated with WM+ software support, the included update will add that

Well sure in the end all DRM/Copyprotections are beaten, but the point is to delay it as long as possible!

Currently all USBLoaders simply return the "default" BCA bytes NSMB checks for, if now future titles implement the same code it will go by unnoticed.
If nintendo checked the per-game part too, it would fail and scene release would need to dump and supply the BCA again.

I think your were right, it was DKC which had this BCA check...
not MG2, sorry

Also all BCA bytes are _unique_ as they hold information about certain marks on the disc which are unique per disc.

It's nintendo's own stupidity to only check the static part of the BCA data, no not even the per-game unique part ...

Nah, they're not unique. My gues is they're related to where the disc was pressed or something. Out of my 20 or so games, I've only seen 3 different BCA strings. The one on NSMB is unique because it has that extra byte in the normally unused area.

Edit: Whoops, they are unique. I was only thinking of the first 4 bytes... the rest of it looks like a timestamp followed by a checksum. Most likely not known at compile time.
