Joust ?-??-83

 

This is very very close to the final version.  The only differences seem to be some changes to the startup vectors and some source code snippets that are still visible in the rom.  Neither of these have any effect on the gameplay.  This isn't surprising given that the game was originally developed on the Atari 5200 and quickly ported to the 8-Bit.
