That's a weird error, I've never heard of it before. Since you said your cart is used, I would suspect that it is the cartridge.

I bought it used, so I'm worried I got screwed, but I don't want to make any accusations if it's not their fault.

I've seen this sort of thing before, sadly there is a lot of fake games being sold on the net mainly ebay and some end up in second hand shops because people cannot bare them any longer. This message comes up in fake cartridges because they've copied on to their own type of forged cartridge which in this case misses the components needed to run the game inside it.
