Tennokoe BankPC-Engine Japanese (NTSC-J) Games
So, Hudson recognized that their systems weren't great at saving games, so they introduced the Tennokoe Bank cards so you could back up your saved games, and even take them from place to place. Unfortunately, the Tennokoe Bank cards were backed up by batteries that have basically all died, so we're just assuming that these don't work. Also, we don't exactly know where to put them, so they are under games, but they aren't really games.
