Keitai Denjū Telefang (携帯電獣テレファング) is a series of video games produced by Natsume and published by Smilesoft. The games are monster-battling games, where the player contacts various creatures using a cell phone-like device called a D-Shot in order to get them to battle the foes he or she will encounter. The name of the series derives from Keitai, which is Japanese for "cell phone," since phoning creatures is an integral part of the game, and "fang," to symbolize the various beasts involved.

Please read the authors' comments for more details. Of note the previous publication relied on an emulator bug for it to work, whereas this one has been console-verified and a video of it can be viewed right here.
