I have never seen any pirated gamecube games here.... I think it's something to do with the media it uses it.
And that's really funny, because it's the only next-gen console being oficially produced here in Brazil.
I've seen X-Box pirated games being sold here in Brazil, so my bet some people have imported it or something, but I don't know anyone here who owns one.
And pirated PS1 games you can find being sold at every corner...
