Yeah, it does so much.
I found a nice DS emulator. google ds emulator and it should bring you to a website that rates like four of them, and it's DeSmuME. It's pretty cool. Although the game I wanted to play it with wouldn't work too well. It came to the menu after like five minutes and I had to find my way on a black screen, and when I got it started, only the top screen, the bottom screen menu and you're health/mp would work... So I got kirby, that's fully playable with some glitches. But...I'm waiting for a newer version so I can play Dawn of Sorrow. I beat Aria of Sorrow with the good ending. It was soooo easy!
