Digimon game where you shake the handheld(read)?

I cannot remember the name of it. It comes in different colors, its probably based on the first of the series. It only has 2 ons with a kind of d-pad in the center with a screen that only shows 8bit picture of the digimon. On the top there are 2 "spikes" jutting out where you could connect with another person and battle them.
