Copy DS Game From Computer to DS Options

There exists on the Internet a slew of games designed by individuals
or a small groups of amateur developers. These "home-brew" games are
available for most systems, including the Nintendo DS. Unfortunately,
these can only be accessed on the PC and so require a third-party
device, such as an Edge DS or CycloDS, that allows the games to be
played on the Nintendo DS. Using an SD card as an intermediary, your
Nintendo will be able to play home-brew DS games.
