If so, how do you get your VC games back on the main screen? I can see them in data management, but it's like they've been erased from the main menu and I don't see a way to get them back. Anybody have any suggestions?

you should be able to re-download them. I would guess that is what you need to do. When my Wii was in for repairs they actually sent back my original console and nothing was changed.

go back to the Wii shop channel and re-download them.

I thought of doing that, but it said it would take up even more memory. I have to delete them all from memory AND redownload them all? That is pretty annoying.
