If you want to carry three games around with you and your Nintendo DS Lite, it's not too tough. Those little game cards are tiny, after all! But what if you want to have all three of said games plugged into your DS at once? Well, that's not as simple.
The Blaze NDS Lite 3-in-1 Game Selector lets you do just that. It rides on the back of your DS Lite and connects to the game cartridge slot via a cable. You can then pop three games onto the back of your DS to play whenever you want. Is it worth the $14 just so you don't need to swap out the carts? That's for you to decide.
