ROM Hack [powersave] question about region

[manpaint]

A usa save works on a canadian 3ds?
or all game have unique save?
someone pass me a usa save for mm3d?

It's by region and system. So powersaves would work on a US and CA 3DS, but each 3DS encrypts their save and is unique. Unless you use something like Gateway.
