Members of the Nintendo 3DS Ambassador Program get access to ten free NES games this week, along with a hilarious surprise in the form of a profanity-punishing system crash. As YouTube user grandmaster101587458 demonstrates above, entering the password "ENGAGE RIDLEY MOTHER F*CKER" in Metroid will cause the 3DS to lock up.

While early speculation suggested that the crash could result in homebrew-enabling buffer overflow exploits, any such loopholes are unlikely, given that Virtual Console games run in a virtual environment of sorts, and that system commands be restored by ejecting the SD card. Still, it's a neat little trick that you can show off to your friends, if nothing else, and having the power to cuss an NES game into oblivion is reward enough in itself.

The password also crashes the game in certain NES emulators, though it produces different results in others. From what I could gather, it also crashes the original cartridge version, resets the game in the Metroid Zero Mission edition, and is not accepted at all in the emulated Wii release. The more famous "NARPAS SWORD" and "JUSTIN BAILEY" codes remain unaffected in the 3DS Virtual Console version of Metroid. So, cheaters are fine. But potty mouths are not welcome.
