Why not download ALL 2000 Nintendo DS games (FREE), load it up on the R4DS (a popular storage device) and play on your Nintendo DS. I just bought one of these for my children and its truly impressive. My kids now have new games setup for themselves weekly. Extremely easy to use and setup. I do not have to buy single games anymore due to this. Saved me hundreds of dollars buying games for them. I cannot see any reason not to get one of these. i've also recommended them to my friends and relatives and they are ALL shocked!

You can find further information in the link below. You will be shocked too! Good luck~!
