Title: [SOLVED] [QUESTION] Changing MPQ names and make wow recogniz
Post by: Kiun on July 09, 2014, 04:21:09 pm

For what I know, WoW only recognize patches called 'patch.mpq', 'patch-2.mpq', 'patch-A.mpq' ...

Would be possible to make WoW recognize a patch called for example 'MyCustomPatch.mpq'?

This will require modification of the client binary. There is a table of MPQ filenames to load. Just looking for "development.MPQ" will lead you there. Note that you need to specify the correct mode though.

Sorry schlumpf, I'm a bit inexperienced in this field. By modification of the client binary you mean editing WoW.exe?

Yes.

There is a list like

somewhere inside. there, just overwrite an entry. appending likely is way harder. note that the integers between filename offsets have a meaning and determine if a file is loaded or not, required or not, etc.

Ok, now I have to ask you about where is that image from? A program tool maybe? What do I need to edit the client binary?

Thank you.
