Nintendo DS

If anything, the DS’ success shows that rampant piracy doesn’t necessarily kill a console (a theory often spouted by Dreamcast fans when their “PS2 killed DC” argument gets shot down). The now-infamous R4 card was a cartridge that you inserted into the DS; within it was a MicroSD card that contained pirated DS ROMs, and the number of games one could carry was only limited by the size of the card itself. Of course, Nintendo has been attempting to get the card completely banned from all retailers, but that’s going about as well as Prohibition. There are just too many small, shady retailers out there, and too many cards running around like cockroaches.
