All we know is that it was over a dozen games, and that Astroblast, Frogs and Flies, Armor Ambush, Space Attack, and Star Strike were included.
If it had been exactly 12 games, I think we could have surmised it was the exact same 12 games that were in Atari Vault. Since it was over 12 games, we have no real good idea what they are exactly.
I would be willing to bet money that International Soccer, Super Challenge Baseball, and Super Challenge Football were included.
