I just bought a used copy of Elite Beat Agents. When I put it in, and went to the single player mode, all of the levels said "cleared". My question is this....is the memory for the DS games stored on the actual game cartridges, or on the DS? Either way, I looked on the DS startup menu, and on the Elite Beat Agents menu for a place to erase or reset the memory for that game so I could play it like it was new, but I couldn't find a place to do that. Can anyone help me out?
