No..Dungeon Explorer just came online today. It was online in the UK last week, and Japan has had it for some time. But this afternoon was the first time Dungeon Explorer has finally shown up. And yes...on my Wii, it was also not listed as a new title. My thought is that it was supposed to have been released on the US servers sometime ago, and perhaps was an oversight?

I'm betting these games are sitting on a server with a flag to make them available or not and all that is needed is for whoever controls it to simply have the game suddenly appear to us. In any event..the VC games today were:

Gradius for NES
Soldier Blade for TG-16
and
Dungeon Explorer for TG-16.

I have exactly 600 points left and Dungeon Explorer will likely get those...
