2。 Psv can play psp, provided that you buy genuine products online. . . . Ds and gba can't, because there is no crack and no simulator. 3ds cannot play psp games.
3, wifi is the conventional way, psv can also buy 3g cards, but the traffic is very expensive. Suggest Hong Kong clothes, the game is cheap, but the psn server is too bad.
4, psv feels better, the screen is bigger, 3ds is ok, but I prefer Sony's psv, which should be based on personal preference. I think the 3ds button is too hard.
I don't understand what you are asking. If it's 2 100, you can buy a quilt, but the psv game you want didn't come out. At least 3ds came out. In terms of price, psv console 1600, 3ds general 1200, and the game is similar, 200-300, so weigh it yourself.
6, don't think about it if you don't know rpg, but you are basically playing music and fighting. It doesn't matter. I really can't. There are strategies. However, I suggest studying. If you like games, Japanese is not difficult to learn.
7. This is not clear
8, depending on which one you like, I think you can buy one first and then buy the second one when you have more money. They are both kings.
