Bugs and Known Problems
-----------------------

2. A few programs cause the emulator to enter its built in debugger. The
   reason for this is unknown at the moment. It might be use of undocumented
   instructions. (Atari Tennis)

3. Player missile priority is ignored - not really a bug, it's simply
   not implemented.

4. Antic Modes 2, 3 and f which display two true colours and not one
   colour with two luminances. Should this be called a bug or feature? -
   its easy to fix (for an example type POKE 709,40). Personally I
   *like* being able to get solid colour antic 2 characters on the
   blue background (e.g. RED on BLUE) but technically it's wrong.

5. Burried Bucks and Caverns of Khafka player to playfield collision
   detection is broken. This is a result of only refreshing the screen
   once every four frames. The collision detection indicates to the
   program that no collisions have occured during these skiped screens.
   Both Burried Bucks and Caverns of Khafka use this to drop something
   until the objects hits a playfield object. The result is that the
   object drops 3 out of 4 frames even when touching a playfield.

6. Test Sound Implementation for Linux SVGALIB needs a printf("\n")
   instruction before every note! The program doesn't make any
   sound if it is removed. I have noticed that the title screen of
   K-Razy Antiks has different coloured letters depending on whether
   sound has been enabled.

7. Reset and Coldstart do not work when emulating either the XL or
   XE.
