That's nuts. I'm sure if the DMCA covered it, there'd be cases on record of it happening (too lazy to search). I have no doubt there's a cases for selling counterfeit games but to outlaw the possession of the cart itself is ridiculous. A 1 year sentence is even more ridiculous.

They don't seem to care about NES/SNES/N64/GB/GBA flashcarts anymore however, those are readily available from NA and EU based stores.
