Hehe, we all went to Korea, so we must buy the Korean version of NDSL. Note that it is NDSL, not NDSI. Although NDSI is the latest model, it is still too early to buy it, because there are too few games corresponding to NDSI's two new functions (camera and microphone), so it is appropriate to buy NDSL. If the configuration of NDSL depends on whether you support genuine or pirated games, a genuine game will cost a lot of money. Since you said Korea, I don't know how much it costs. You can also buy a burning card to play piracy. The difference between pirated and genuine is that a card has only 1 game, which is expensive. Pirated games are downloading the ISO of the game from the Internet to the burn-in card, and then inserting the burn-in card into the game machine to run the game. Other configurations, that is, bags, protective covers and the like, headphones are not recommended to buy, NDS sound quality. . . . .
