The Nintendo DS R4 Flash Card also known as the Nintendo DS R4 Revolution Flash Card is a next generation Nintendo DS Flash Cards. The Nintendo DS R4 Flash Card is one of the most popular, if not the most popular Ninendo DS Flash Cards on the market. The Nintendo DS R4 Flash Card is the current top-of-the-line in Nintendo DS SLOT-1 Flash Cards. It is just an amazing little device. Like the original Nintendo DS card size, it is a near complete solution, only needing Micro SD Memory as the only additional component to deal with. Thats up to 8GB of games storage. You can easily store 100+ games on that kind of memory. To simply put it, this is a must have peripheral for any regular Nintendo DS/DS lite owner.

I recently purchased two for my boys DS lites. Yes they are the best buys that you can get I backed up all my games *wink wink* and now they can both have all the games and not worry about changing cards.
Picked up a set of R4 card and small SD card for $70 dollars. Thats a 4G card not a 8G as they were a bit extra and I store all my games on computer and then swap when they want new ones.

For sure the best buy out there for peoples DS.
