Is an ADB joystick fully compatible with the mouse?  If not, then you
would also need a driver for the joystick.

This would let you use the joystick as a mouse.  It would be usable in
any program which can be run via GS/OS (booted from a system disk with
the driver installed) and uses the Event Manager to read the mouse.
This is likely to rule out most games, assuming they support a mouse at
all.

If the game expects a joystick, then this method is no use at all,
because there is no way to hook into the joystick hardware, or even the
PREAD routine in the firmware.
