This is a beta version of a modification that I did to Randy Spurlock's
Apple II Emulator (apl2em) which supports the PC analog joystick.
Be sure to press numlock to get into joystick mode.  Also, I had to
remove the joystick emulation via numeric keypad for now, but in the
next version I put out I will have both supported.
Please report any bugs with the joystick part, I kinda did this quickly
so I hope it works ok.  Make sure your joystick is centered.  You can
make a little applesoft basic program to test it :
10 print pdl(0),pdl(1)
20 goto 10
I had to multiply the PC's analog joystick values by 4 in order to get the
equivlent range that the apple joysticks have.  Also, the PC bios
routine int 15h service 84h was too slow to call every apple cycle,
so I only read the joystick every 16 apple cycles.
Please let me know if there
are any sluggish responses from the joystick.
Again, this is a quick release of this, I will be making more permanent 
changes in the future.
