Anyone know how to read the Joystick....
if you are using an AT (286 or later), here's the easy way.
Use Intr ($15, Regs), and load AH With the $84, then load
DX With 1 to get the joystick status' and 0 to get the
button status. if you use DX=1, it returns:
AX x of joystick A
BX y of joystick A
CX x of joystick B
DX y of joystick B
if you use DX=0:
AL button status, bit #
4 joystick A,button 1
5 joystick A,button 2
6 joystick B,button 1
7 joystick B,button 2
