Yes, you can buy this program for the DS that lets you upload music, small games, and videos for your DS. I bought the thing myself and i really like it. Its a great thing to take on long trips. The downsides are:
- It only has 128 megabites of storage
- The sound isnt very loud
- It only playsa cetain type of video file, but the package comes with a computer program that lets you transfer other files into this type.
