Hi I'd suggest to add the: gamepad settings in options. Way back in 2009 the game had the setting, but then for no reason it was removed from the game. I hope you'll add it in game so it would be easy to change the buttons and play with the gamepad.
??? U know u can play with a logitech controller its like $25 buy it at any walmart target u can use gamepad or joystick easy nothing to install
