Keyboard hacks will not work for what the person is asking.
EA sports games (and others too) let you use the "keyboard" for only a single player. Even if you add more physical keyboards, even USB ones, the game only sees one virtual "keyboard" consisting of all the physical keyboards combined. The biggest problem on PCs is that you can't play two players unless you buy at least a gamepad or joystick; ie an ipac can't control 2 players, and you
have to buy a gamepad to do so.
The reason EA does this is that it's so much easier to set player control by device rather than letting different keys control different players, especially with the 4 hundred console ports the games have. Lazy.
You could use a keypad hack and the ipac ...
Do you mean "keyboard hack" or "gamepad hack"? With a gamepad hack it could work, but keyboard would not.
