The Elmdor-Appreciation-Out - Number of practitioners: one.

so a while back I downloaded a bunch of gc games and today I decided to setup dolphin. I wanted to load a game to check it out and noticed that all my games are in rvz format WTF? can they be converted?

I think those 'just work' on Dolphin:

That thread suggests that Dolphin can convert them?
