I've got a week off and I'm trying to add the Tandy Hi-res joystick
adapter to OVCC.
Where can I find a theory of operation for the Hi-res joystick and also
the standard joystick device?
For the standard joystick I have been looking through the OVCC code and
can see where the SDL joystick input routines (I wrote) get the host OS
joystick values but I can't figure out where it places that joystick pot
value into an emulated CoCo register.
I assumed it would have written the value into $FF20 so it could be
found later by what was running on the emulator, but it doesn't appear
to be doing that!!!
