It's really a beautiful console. The appearance is really top and I did not really notice "screen tearing". If I had to blame him for something there would be: The edges of the directional cross a little too angular (they hurt a little at the fingertips in the duration with games like Tetris). A slightly larger screen would also be a real plus, like that of the GBA (2,9 "against 2,4"), to gain readability on the texts in the games. A larger one-centimeter device on each side would also have improved grip. It remains in any case a superb machine at a really unbeatable price. The rendering of the screen is superb, no bug, a superb finish. The performance is largely sufficient and make it possible to save the battery.
