I doubt any good square soft game will be released on the virtual console yet... Maybe soon

Grab a bittorrent application and go to

I beleive what you can do is download this (is has secret of mana on it), burn it to a cd/dvd, and play it on a modded wii.
Im not totally sure about this, but thats how I believe it works...
