The Nintendo R4DS Revolution is the most popular Nintendo DS R4 card on the market today. It has been available for quite some time now and it is still one of the favourites available today. The R4 Nintendo DS card does all our would want to be able to play musics and watch moives on our Nintendo DS or DS Lite. The limitations with this card are that it does not accept memory cards with capacities bigger than 2GB microSD TF Card as this device is not SDHC compatible. However 2GB is more than enough space for most people. The other limitation is that this R4 Nintendo DS card is NOT compatible with the latest Nintendo DSi video game console.
