Downgrading
=====================
This will allow you to install and use SA-MP, Multi Theft Auto, and mods.

1. Install steam version of GTA SA.
2. Downgrade with this tool: http://gtaforums.com/topic/753764-relsasteam-downgrader/
3. Game is now compatible with SA-MP and Multi Theft Auto.

Making game moddable
======================
This is required for most fixes you need to make San Andreas look and run well on modern systems. After the following steps you will be able to easily add and remove mods, mods will all be contained in the same folder and can be easily disabled or enabled from the ingame menu.
3. Install ASI loader by replacing your "vorbisFile.dll" and "vorbisHooked.dll" files with these: http://www.gtagarage.com/mods/show.php?id=21709
4. Install Mod Loader by placing "modloader.asi" and the "modloader" folder into your root SA directory: http://www.gtagarage.com/mods/show.php?id=25377

Recommended Improvements
======================
I will only recommend things here that improve performance, visuals, or fix bugs. I do not endorse gameplay altering mods on multiplayer. Mods are installed by extracting mods into subfolders contained in your "modloader" folder.

Silent Patch - Extreme amount of bugfixes, tweaks, and improvements. -- HIGHLY RECOMMENDED --

Project 2DFX - Increases draw distance and adds special LOD lights. Personally the following settings in SALodLights.ini:
CoronaRadiusMultiplier = 0.25
[AdaptiveDrawDistance] Enable = 1

San Andreas - Vanilla+ Modpack
======================
To make things easier, i've compiled my favorite mods from above and some other stuff not listed. You simply need to extract the modloader folder to the right place to install all the mods.
