I think Fallout 1 was never patched beyond 1.1.
Fallout 2 is updated well beyond 1.02. Official patches goes as far as 1.04, and then there is fanmade patches 1.05 and upgrades to 1.05 and so on. Also, in case of Fallout 2, if you have certain version of the game (European version, IIRC) and you don't have children in the game, you need special patch for that too.
I suggest searching patches from
No Mutants Allowed - Your Post Nuclear News Center! as that sited should contain all the needed patches to both games. And before you ask, I definately suggest that you patch Fallout 2 to 1.05, as 1.02 is very buggy and stays such until to 1.05.
