Two extremely rare "unreleased, one-of-a-kind, never-digitized" Nintendo NES games have appeared on eBay, according to a tweet from the Video Game History Foundation's Frank Cifaldi, seen by Kotaku. One of those, called Battlefields of Napoleon, was only ever released in Japan. The other is a cartridge from Rare, and appears to be the demo of one of the few games ever developed for the Nintendo Power Glove. According to the eBay listing for Battlefields of Napoleon, the game was "rescued from a dumpster after The Learning Company acquired Brøderbund in 1998 and subsequently discarded most of the historical assets." The items in the lot include a WATA certified prototype on a development board and two additional CHR ROMs.
