Verbyte: 0x16
Hashes: Here

The Game.dll file has been changed so that the automatic determination of the Verbyte is no longer operational ([s]C7 85 4C FD FF FF XX XX XX XX 89 8D 50 FD FF FF[/s]). Damn >:(

Of course, Warcraft's verbyte has always been the same version as its minor version number...

I wouldn't trust to that either, though... :-\

[s]Also, the size of the files has broken my dynamic zip file code, even though PHP's supposed to have 40M allocated to it, so the hash download's not available at this time.[/s] Fixed.

When you see the verbyte's consistency for over a decade with many different clients, it seems much more reliable than searching for a pattern of instructions.

Question: What could have contributed to the major filesize increase with game.dll this patch?

Maybe the new features as documented in the changelog?

Anyone bothered to dissasemble the diff of the two files?
Aside form that, the things in the change log would account for *some* of the increate in the game.dll but i agree.. 2mb(?) jump is weird.
I asked myself what that was when I was uploading it to my server :P

Perhaps the new version was built with a different compiler version or different options, such as switching from dynamic CRT to static CRT.  Perhaps debugging code was mistakenly shipped, causing the file to grow due to all the extra debug strings and/or sanity checking.

The best way to find the correct answer is to analyze the files, as Hdx suggested.  Start with easy tests like checking whether the DLL dependency list has changed.  Move on to checking whether functions known to be in the old version are unchanged in the new version (as opposed to picking up instrumentation).  If that doesn't turn up anything useful, then try to identify functions which are new in this version and determine what they do.

The new one has MSVCR80.DLL as a dependency; the only function is still GameMain.

Andy, GameMain fills a struct with addresses of other functions in the library. [Pretty much the same way snps worked]
