Advantage and Disadvantage to this:
ADVANTAGE: A Friend of mine has a Wii and for some reason or another (he don't care of his stuff too well) it's already gotten to where it does not read Discs. He has probably about 20-30 Virtual Console games. He bought another Wii (for a very premium price at that) for playing his Retail games (which in a way sucked, b/c i had borrowed his retail games and had to give them back once he bought another Wii!). Now he's got 2 Wii systems...one that he has his Virtual Console games on, and other he uses for playing Retail games...Knowing it wasn't going ot work, we tried to copy the games and put them on his new Wii with no success.....It would be nice in his case for him to transfer his games to his newer Wii so he don't have to change machines.
DISADVANTAGE: This would really bring on more piracy if brought online. It would be on Torrent sites everywhere and Nintendo would stop releasing Virtual Console games which was a big selling point of the console!
