If I buy another copy of Pokémon Black/White, does it count as another save file?

Question

I already own a copy of both black and white, and me and a friend are doing a playthrough together. Was wondering if buying another copy of the game, would that count as a new save file? Or would both copies boot up the same save file? I own 3Ds XL's. I wanted to have a separate playthrough for a shiny only run.

I think it is a separate save file because that is the case with the gen six and seven games. I own both oras, two copies of um, and us, and they each have their own separate save file

Answer 1

Prior to LGPE, save data is stored to the cartridge, not the console. This means that any individual cartridge of Black/White will start a unique save file, even if inserted into a DS that has already played a different cartridge of Black/White.

If you're going to downvote a correct answer, you should probably explain why.

This is absolutely 100% correct.  I own 5 copies of Pokémon Black alone and can personally confirm this.

Thank you!
