At last year’s Nintendo Game seminar the house of Mario worked with a number of students to create a handful of experimental Nintendo DS games. Rather than being kept in storage for no one to play, Nintendo is releasing these games for free at DS download stations around Japan. Each game will be around for two weeks before it vanishes from the station and to some extent existence. Since the DS does not have flash memory once these demos are pulled off they won’t be playable unless someone keeps a DS in perma-sleep mode.
