Since there's a lot of them and having interest in the idea, I thought I'd make a continually updated list of the games that would be on the Wii (or upcomming Wii U) Virtual Console if not for licensing, technical, ect. issues.
NOTE:And just because a game is on this list it doesn't necessarily mean it will never be released on Virtual Console. Some games can be rereleased with edits working around the issue.
NES/Famicom/Famicom Disk System
N64
*Because Microsoft has no interest in the handheld market, the game may be easier to rerelease. Although Rare's orginal franchises may count as Microsoft franchises and Rare may no longer be interested in their older franchises.
Edit: 14/09/12 Added in Pokemon Stadium (Japanese) and Pokemon Stadium 2. Seperated the DuckTales games.
