Earlier this year a Neo Geo rep said something about making their VC games online playable on the Wii. Prior to the Wii launching Nintendo invested some research into MAME and Kaillera.
Fast forward to now and you can see Nintendo was very serious about online gaming. If Nintendo wants to turn a game like Chrono Trigger into a 1 player game with 4 other people watching online(already possible with Zbattle.net), they can do that. If they want to save replays of games, they can do that. Anything is possible. Now we'll get a better idea what is in store next year. Nintendo's President Iwata said he wants to keep the momentum for the Wii at all costs.
