Half-Life: Source 2004 mod

The main plot of this mod is to patch and update Half-Life: Source, that was released in 2004, to the stage that it must to be. What does this mean? I would like to make Half-Life: Source use all Source Engine features, but with Half-Life 1 original mechanics. I have found Half-Life 2's December 2004 source code on the Internet and decided to use this December 2004 build for my mod. Why i decided to do the such thing? So i will explain it to you. This is the first release of Half-Life 2 source code, so, there are used some old stuff for Half-Life 2 Beta, so as you understand, it makes the entities from Half-Life: Source working practically like in original Half-Life 1. I have tested it and and some features that was broken in the latest releases of Half-Life: Source right now working in Half-Life: Source. So, if you are interested, you can help me in one way - just find other bugs that must to be fixed.
