When Nintendo replaced the blood in their SNES Mortal Kombat version with green goo the internet started buzzing with news of a code that restored the bloody mess of the arcade game. After all in the Mega Drive version all you had to do was press A - B - A - C - A - B - B and the blood was back in their version of Mortal Kombat. So was there a code?Sadly NO it was just a myth.
