Issues with two player games
From u/Snowbro88 on Reddit
HI have come to report a problem with games that support 2 players such as Mistigri or Amazeball Dudes, when I play in single player mode, when you press X (button to attack) automatically the second player enters into action and in fact the two characters both are controlled in a rare way with the same control

Edit: This bug also messes up the controls on X-Wing Vs Tie Fighter
