This, as well as vilifying emulation (despite admitting that legal emulation exists), patenting basic game mechanics, and cracking down on a charity, have shown me that Nintendo is just pure evil.
They go after emulation because all the times they tried to go after debugging tools used to dump roms and copy games, they lost. Even if they win their arguments against emulation, it wouldn't stop the process of copying the game just the part where you could play it. And then it would also bite them in the ass because they themselves use emulation to continue to sell you shit from the 80's.
