I just played Hot Shots. A lot was in Japanese so I had no clue as to what I was dong, but I didnt care since i was in love with the graphics. After fiddling around with the menus for a while I got into a game and it looked great. Well, a bit watered down PS2 game... but still much ahead of the DS graphics.
