This is a list of things that need to be done
---------------------------------------------

o X11 audio support (tricky!)

o Port this thing to PCs, Linux and Amiga. All parts but the unix version are
  a bit in bad condition.

o The obsolete variable "countdown_rate" is still in use within
  "atari_amiga.c" this should be a trivial change, however I'm reluctant
  to do it without an Amiga to check it. I've left it defined in "atari.c"
  so that there are no linker errors on the Amiga.

o Joystick support for DOS version

o Sound output for DOS version

o Correct handling of 5200 controllers

o Correct artefacting even under players that change the background color
