Mine so far are
Legend of Zelda
Sonic
Gunstar Heroes
Dr. Robotniks mean bean Macine
Bonks adventure
I just have Golden Axe and Columns. There hasn't been enough nostalgic blood within me to download anything else that's come out. Well, that and I don't have a Classic Controller =P
no vc games for me either. magnetic is that you from scionlife too?
In order of purchase:
Mario 64
Solomon's Key
Mario Bros.
Bomberman
Donkey Kong Jr.
Military Madness
edit: Solomon's key is fantastic. The continue trick is necessary for me though (hold up and 1 and 2 at the GDV screen).
magnetic is that you from scionlife too?

Even though I already own solomon's key, it very well could be my first purchase as well. Being able to save means I might actually be able to beat the game, lol.
And for all you non-Solomon's Key haters, buy it. IT'S ONLY $5, and it is well worth it.
So far I have:
The Legend of Zelda
Gunstar Heroes
Bomberman '93
I plan on one day being able to play all of the home console Zelda games on my Wii :-)
I think Gunstar Heroes is the best virtual console game available right now, it's loads of fun. You should check it out if you haven't yet!
By the way... for all those people who've downloaded Mario 64, how does it run on the VC? I've been a little bit hesitant to download it for fear that it may not run as well as it did on the N64.
i got donkey kong, bomber man, and legand of zelda
I only have Super Mario 64. Waiting till x-mas for the original mario.
At least you won't have to worry about lineups and shortages
