Moving before the round is not a gameshark code people. You hit a direction, press start, and you move. Unpause to stop moving. Amazing.
Multi jumping is done by jumping and mashing the stance change button. You can cover the whole screen in one jump. NOT A CODE.
Speed. Some morons have said people have used a BRC speed code. Most characters have vast speed differences depending on the stance they're in. For example. BRC is FAST is his weapon stance, and slower than shit in his other 2. There are no speed up codes that I've seen.
It gets old when idiots drop and say you're using a gameshark or codebreaker because they are ignorant as far as game mechanics. I've played fighting games competitively for years, and I've never seen a game community with more excuses and whinning than the MK community. By competitivley I mean traveling to tournies and playing for $, not going to local arcade like the majority of numb nuts around here.
