Nintendo 3DS Game Card

The Nintendo 3DS Game Card is the main form of media storage for distribution for the Nintendo 3DS system. The game card's memory is normally at 2 GB with most games, but Nintendo announced that Resident Evil: Revelations and Metal Gear Solid: Snake Eater 3D are going to be distributed under 4GB game cards, 2x the memory of a regular Nintendo 3DS game card. The notable different design on the 3DS's game card compared to the Nintendo DS's Game Card is that there is a little "knob" on the side of the game card which prevents Nintendo 3DS games from being played on Nintendo DS systems.
