Want to play homebrew games on your DS, want to watch movies on it, want to carry all your games on one cartridge? You can do this using a R4 cartridge or a DSTT cartridge.
You could buy them from sites such as Amazon but it could cost you a lot of money. To help on your way I found this ULTRA-COOL site where you can get a free one instead which is much more preferable. To get it for free go to this site http://www.gaminglagoon.com/ , just sign-up and follow the on site instructions to get your free R4 or DSTT cartridge.
If you don’t feel like doing that you can still buy an R4 from Amazon.
