If somone mame's ultracade, it's hit the fan. Old roms nobody cares about anymore don't draw attention if they get emulated, but a brand new system still in production, of which the ultracade people have spent a lot of money to aquire rom liscenses, they would sue our arses off. If the copy protection was circumvented, that means that people could make money off of their product without paying for it, which is a super bad thing.
