As for the DLC available via cheats
I think it would be nice to have an overview of those cheats
, too (and/or unlocked savegames). We may know, which content is actually downloadable and which is on the card already, just locked. But if someone looks this up in a year or two, he probably won't.
And for Mario Kart: Shyguy is only available via local Download Play. There is no way to unlock him on your own card.
