It seem like the special move never work when you want them to, and only work at random.

Is there a trick to doing the special moves easier? In the arcade version I read if you hold down the attack button, then press the movement commands, then release the attack button it will work, but that only works for the arcade version.

Is there any trick for this version to do the special moves easier?
