I have recently lost gameport -> USB adapter that came with Wingman Extreme Digital 3D. Since I don't have a desktop PC anymore (only notebook) I need the adapter. Is there any way I could build or buy a new one? Does the adapter only extend wires from a joystick or it remaps signals in any other way? One of the wires from joystick is +5V and one ground. For that I am quite sure. Now I only need two data lines, + and -.
