The keyboard controls for this game are horrible, so I was wondering if there was a way to remap it so no one is stuck using a keyboard, i.e one guy using a joystick, the other guy a mouse.
I personally prefer the keyboard controls to that of the mouse, but I digress... I presume the stage you're at is that you've got both the mouse and the joystick working, but both of them apply to Player 1 and you can't get it to think of the joystick as Joystick 2.
Fortunately, a solution exists - on the Main Menu, go into the Disk menu (of all places), and you'll find a Mouse option - from here, you can switch the mouse to Player 2's control. Hope this helps.
