You may have heard of these R4DS cards which Nintendo DS owners seem to be talking about. That doesn’t mean much, however, if you have no idea why these cards are important.  Any Nintendo DS owner should, however, consider how beneficial they could be with making their DS even more valuable. When you put an R4DS card into your DS, you will be transforming it into a platform which will do a whole lot more than simply play video games!  It will have the ability to easily become a portable mp3 video player.

The R4i card itself is an adapter card which will plug into the slot on the DS where you would normally insert the game cartridge. This adapter card can read the technology of the DS and interact with it easily. This way, using homebrew programs which have been written using the same language of the Nintendo DS, an R4i card can turn your game system into a reader that will be able to interact with a number of additional programs.

This should easily influence the way that you use your Nintendo DS in day to day life.  If you take the time to convert audio and video files into the proper format for the R4DS card to read, you will be able to access those files through your Nintendo DS. This can give you the ability to have an audio and video player in your pocket using the same technology that you use to play video games, which is incredibly convenient!
