Nintendo Japan has revealed that the GBA's F-Zero: Falcon Densetsu - Legend of Falcon to you and me - will feature four-player multiplayer support using just one cartridge.
However, this will only offer a limited number of craft and tracks, with any custom vehicles being unavailable for use. For full-power F-Zero action, Nintendo has included a Multi Cartridge Vs Mode that will see all ships and tracks, as well as custom vehicles open for use.
It is currently not known if infra-red support will be included, though it was expected that Legend of Falcon was to be the first with such functionality in place, ready for the wireless add-on next year.
More as it breaks.
