I was recentally looking over my 5200 prototype roms, and I discovered that I'm missing some. I know someone here in the past had posted owning an earlier version of Microgammon with only one level of difficulty (dated 7-11-83) and an early RS Tennis prototype that was called The Atari Open (dated 11-19-82). I think the owner was planning on selling these, but I never saw what happened to them.
Has the rom for the Ballblaster version of Ballblazer been released? What about "killer hard" Centipede?
There's also a version of Track and Field that's called The 84 Games somewhere.
How about the Millipede proto with the 1983 copyright?
Tempest
