This is a sequel to the original Famicom Wars. I think it contains the levels from the original game, as well as new ones. It doesn't seem to have a campaign mode per se, instead just a collection of maps and commanders of varying difficulty. I first encountered it while looking through Satellaview demos on my MiSTer. I later realized that the full game only was available as a download to a Nintendo Power cartridge, Nintendo's unique kiosk download service.
