Ok I want to buy a Jap. X game but my 3DS is US, I know this is most likely just a simple answer, but google says things about PAL and region locks and such, but will the Japanese game work on my 3DS?
The 3DS in general is region-locked, so if you wanted to get a Japanese copy of the games you also need a Japanese 3DS, and same goes for other regions - you can't play a game from a region if you don't have a corresponding system.
