Another good idea of copy protection is that it'll show goatse or something on the screen if it detected a copy-protection compromise and flood your computer with viruses, trojans, and worms to the point it's unusable. For a Cartridge game, I'd say it should overload the console to the point it fries the circuits with errant code and graphics and ear rape sound. CD games have the copy protection nailed as it is, but still, it should just rickroll you.
