Joust ?-??-83

 

This is very very close to the final version.  The main differences seem to be that the lives counters are facing to the right instead of the left (this is the same as the 5200 version), and that the first player's score is corrupted during the demo.  There are also some source code snippets that are still visible in the rom.

There are some minor changes to the initialization and startup vectors
There are source code snippets at the end of the rom which were removed from the final version:

;BIT 7 IN IN VBLANK, BIT 6 IN DISPLAY RO

Notice the graphical corruption on the score?

 

The lives counters are facing the wrong way too

 

The goal is to survive!
