Players controlling others size
These are all for Player one but they effect the player. So if player 3 code is on, player three will be effected from player 1's key presses. Untill the joker addresses for players 2-4 is hacked this is only for player 1 to enjoy.
These are different to the above as they can affect all 4 players and have different key combinations. As above they are all done from player one's controller but they affect others. Choose the code that will help you the most.
