2.psp can make the player's own system by brushing. At present, it is 3.52, which is quite popular. Through this system, basically all games can be played, and the system is constantly introducing new versions. The process of brushing teeth is very simple, which can be done by hand or in a video game store.
3.nds is the first generation, and it is relatively large, so it is not recommended to buy it. Ndsl=nds lite, as the name implies, is an ultra-thin version, which is relatively small and beautiful. Idsl is a dsl produced by domestic banks or ique, and the functions of the three machines are the same. I suggest buying the smaller ones.
Psp is rich in functions, and the game movie mp3 is online, which can simulate all games from fc sfc md to arcade ps, and the picture is also beautiful. Because you use a homemade system, you need a strong hands-on ability to play the role of psp.
The gameplay of Nds is very good, and the playability of games is very high. Because it is a touch screen, the gameplay is rich. Suitable for young players and female players.
If you can afford it, buy both. If not, choose.
