I'm trying to connect an old trackball I had from the old days to my xbox.
I have a gamepad I've opened up and I'm planning on using it.
On the trackball I had 4 wires +x, -x, +y & -y.
Me thinking this would be easy I just connect these wires to to the buttons left right up & down.
Yeah right

It does something but not great.
I started looking around and found the opti-pac, and thought I need to make something a bit the same.
I'm not interest in spending money, I just want same way to convert the +x, -x, +y & -y to work as the same way a button presses.
Any help?
