Exactly where are these files located, does my program need to download them from Blizzard upon receiving the 0x50 packet back, are they packed inside another mpq? I don't see them anywhere in my d2 folder.

You need to download them from the Battle.net server

Thanks for the response, much appreciated.

You don't need to download them at all.  They contain a single DLL which has a single CheckRevision function that's been desribed and implemented many times by many people.  The latest popular one is BNCSUtil for C/C++/Visual Basic 6 and MBNCSUtil for .NET.
