Jum's A5200 Emulator, Windows Version 0.8 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

10 April 2003

This is an Atari 5200 emulator for Windows.
MSDOS, BeOS, Mac, QNX and PS2 versions are also available.

The 6502 CPU emulator source is heavily based on a distribution
by Neil Bradley. The POKEY sound emulator is from Ron Fries.
The rest is by me :)

Debugger Keys
~~~~~~~~~~~~~

Press H while in the debugger to get help.


Joystick:
~~~~~~~~~

Calibrate the joystick by clicking on the "Calibrate" button
in the options dialog.

Joystick calibration settings will be saved in "joy.ini".

Many games do "auto-calibrating" while you play. Moving the
joystick handle in a big circle while chanting "work dammit"
usually gets it working OK. (The same applies when using the
keyboard - press left, right, up, down to let the game
calibrate the controller).


Mouse:
~~~~~~
The mouse does not require calibrating :)
Use the mouse for Missile Command and maybe other trackball
games.
