Huh, you talk as if someone hacked 1.0 into 1.1. These files are different versions of the game, compiled and everything. The hex differences are going to be way too many to count. But if you really wanted to compare at the hex level, just make a patch between 1.1 and 1.0 and look at it through a utility like IPS Peek. Or I guess compare two files in a hex editor.
That's one reason why people use 1.0. It's the only way to have a unified codebase of sorts, due to the fact that we made a better sketch fix than 1.1.
