[Pokemon X] Is there a difference between Japanese game card and foreign game card?

I’ll try keep it simple:1) I bought my 3DS and game card during a vacation in China; and apparently they are all from Japan2) Recently I have received the code from a game shop. A code for Shiny Gengar3) When I did as the instruction said, the system says that my game card doesn’t allow me to receive Gengar

Q: Is the mysterious codes from one region only works for this specific region? Is there any way for me to get a Pokemon via mysterious code?

Thank you very much!

I’ve tried looking for it, guess what I found.

Codes are region locked, but I think they are locked to the location you are, not the region of your 3DS.

In other words: Store > 3DS Region.

Fromhere,

Actually there’s a good chance the code won’t work for you then. The codes seem to be region locked.

Fromhere,

…so please don’t enter if you are not in this region and/or it wouldn’t work for you.

Fromhereas well,

Unfortunately, the codes are region locked I think, so I am afraid it won’t work. A UK code will not work for a US game card.

And lastly, fromhere.

So,Good news: It’s not the game card’s or the DS' fault, both are completely fine and dandy.Bad news: The Gengar code is not gonna work :/

Hope I helped!
