If you want to play GTA San Andreas on a modern PC in 2026, the short answer is: install SilentPatch, ThirteenAG's Widescreen Fix and SkyGfx on top of a downgraded 1.0 executable, loaded through an ASI Loader and ModLoader. Those five things fix the vast majority of crashes, stretched visuals and missing PS2 effects, and everything else is optional on top.

I have set this game up more times than I can count over the years, on everything from old laptops to current hardware, and the core stack has honestly not changed much. What has changed is that the tools are more mature, better documented and mostly open source now. Here is the full rundown, including the install order that actually works and where to get everything without touching shady reupload sites.

Step 0: get your game to version 1.0

Almost every classic SA mod targets the original 1.0 executable. The Steam and Rockstar Games Launcher versions ship a newer build that removed music tracks and broke compatibility with most ASI plugins. So the first step is downgrading. The community downgraders work with binary diffs, meaning no copyrighted game files are distributed and you need a legally purchased copy for them to work. There is a well maintained Downgrade 1.0 patcher on Nexus Mods for the Steam release. If you own an old retail disc copy of 1.0, you can skip this step entirely.

The plumbing: ASI Loader and ModLoader

Two small tools make everything else possible:

• Ultimate ASI Loader by ThirteenAG loads .asi plugin files, which is the format SilentPatch, SkyGfx and most fixes use. Grab it from the official GitHub repo and drop the DLL into your game folder.
  
• ModLoader by LINK/2012 lets you install mods by dropping them into a modloader folder instead of overwriting original game files. Uninstalling a mod becomes "delete the folder". If you plan to install anything beyond the basics, get this early. It saves you from ever needing a full reinstall.
  

• GInput by Silent: rewrites controller handling around XInput, so a modern Xbox or compatible pad just works, with proper button prompts. This one is the biggest reason people downgrade to 1.0.
  
• Open Limit Adjuster: raises the engine's internal limits so heavier mods do not crash the game.
  
• Project 2DFX: adds LOD corona lights so the city actually glows at night when viewed from a distance, instead of going dark past the short vanilla draw distance.
  

• 1. Clean install of the game, then downgrade to 1.0 if you are on Steam or RGL.
  
• 2. Ultimate ASI Loader.
  
• 3. ModLoader.
  
• 4. SilentPatch.
  
• 5. Widescreen Fix.
  
• 6. SkyGfx.
  
• 7. GInput, Open Limit Adjuster, Project 2DFX and any other quality of life plugins.
  
• 8. Only after all that: texture packs, car mods, script mods, through ModLoader.
  

OpenRW is an unofficial open source recreation of the classic RenderWare era GTA engine, aimed at GTA III. It runs with the original game data, so you still need to own the game. For fans of the classics this is one of the most interesting preservation projects around.

GTA IV on a modern PC is rough without help, and FusionFix is the help. It fixes a long list of issues in GTA IV and its episodes: frame pacing, graphics regressions, controls and more. Nearly three thousand stars say the community agrees it is essential.

What is GTAIV.EFLC.FusionFix?
This project aims to fix or address some issues in Grand Theft Auto IV: The Complete Edition

This projects aims to fix some issues in Grand Theft Auto IV: The Complete Edition, as well as add various new features for modern systems. Also available for Max Payne 3 and other games. Install Grand Theft Auto IV: The Complete Edition from your library, then: Download GTAIV.EFLC.FusionFix.zip and unpack its contents to the game's root directory, where the exe is located. Or alternatively download GTAIV.EFLC.FusionFixWebInstaller.exe or GTAIV.EFLC.FusionFixOfflineInstaller.exe, open it, select the game's directory and wait for it to finish. Note: If you get an error while installing, this is likely due to the installer not having write access. Go into the properties of the games directory and change your system's users to have write permission and hit apply, now installation should work. Non-Windows users (Proton/Wine) need to perform a DLL override. You need to tell Wine explicitly that the dinput8.dll file is to be used. There's more than one way to achieve it. Note that Proton Experimental already loads it by default, so you may skip this step. Method 1: WINEDLLOVERRIDES variable lets you temporarily specify DLL overrides.

Multi Theft Auto is the veteran of GTA multiplayer. It turns GTA: San Andreas into a fully scriptable multiplayer engine, and it is still actively developed today, which for a 2004 era game is remarkable. The Lua scripting API is deep and battle tested.

What is mtasa-blue?
Multi Theft Auto is a game engine that turns Grand Theft Auto: San Andreas into networked multiplayer.

Multi Theft Auto (MTA) is a software project that adds network play functionality to Rockstar North's Grand Theft Auto game series, in which this functionality is not originally found. It is a unique modification that incorporates an extendable network play element into a proprietary commercial single-player PC game. Multi Theft Auto is based on code injection and hooking techniques whereby the game is manipulated without altering any original files supplied with the game. The software functions as a game engine that installs itself as an extension of the original game, adding core functionality such as networking and GUI rendering while exposing the original game's engine functionality through a scripting language. Originally founded back in early 2003 as an experimental piece of C/C++ software, Multi Theft Auto has since grown into an advanced multiplayer platform for gamers and third-party developers. Our software provides a minimal sandbox style gameplay that can be extended through the Lua scripting language in many ways, allowing servers to run custom created game modes with custom content for up to hundreds of online players.

gta-reversed is exactly what the name promises: a function by function reimplementation of GTA San Andreas 1.0 US. When you want to know how some game mechanic really works under the hood, you read it here instead of guessing.

What is gta-reversed?
Reimplementation of GTA:SA 1.0 US

A project to reverse Grand Theft Auto San Andreas completely, and to rewrite and document every function. Please join our community Discord: GTA Groupies [The invite is permanent, feel free to share it!] Building this project will result in a DLL file that can be injected into GTA:SA using any ASI loader out there. After the DLL file has been injected, the ingame functions will be replaced by the reversed ones. The game will behave the same. Now if we make any changes to the reversed code, it will take effect in the game. The goal is to keep reversing until we have the entire game reversed to compile a standalone executable. The progress of reversed classes can be tracked here. (needs to be updated) We currently estimate that about 50-60% of the code is done. Since this project is done as a hobby, and worked on at irregular intervals, there's no time estimate on when it'll be finished.

SanAndreasUnity is an open source reimplementation of the GTA San Andreas engine inside Unity. It loads the original game assets and recreates gameplay on top of a modern engine, complete with multiplayer experiments. A fascinating project to study.

What is SanAndreasUnity?
Open source reimplementation of GTA San Andreas game engine in Unity

San Andreas Unity is an open source reimplementation of GTA San Andreas game engine in Unity. This won't be a complete reimplementation, but the focus is on gameplay features, mutliplayer, and creating a framework which will allow easy game extending and unlimited modding possibilities. For more information about the project, read this wiki page. When running for the first time, the game will ask you for path to GTA installation. You need to own GTA in order to play it. Download it for Windows, Linux or Android. The game is tested on Linux, Windows, Mac, and Android. It supports both Mono and IL2CPP scripting backends, so it can be built for any platform that Unity supports, provided that you can copy PC version of GTASA to target device. Game fully works in multiplayer. You can start the game as dedicated server, as a host (server & client at the same time), or you can connect to a server. This works on all supported platforms, which means you can start a host even on Android device. If you want to host a server, take a look at command line instructions and server administration.

ScriptHookVDotNet is the bridge that lets you write GTA V mods in C# or any other .NET language instead of raw C++. Most of the singleplayer mods you have installed over the years depend on this one project.

What is scripthookvdotnet?
An ASI plugin for Grand Theft Auto V, which allows running scripts written in any .NET language on the .NET Framework runtime in-game.

This is an ASI plugin for Grand Theft Auto V, based on the C++ ScriptHook by Alexander Blade, which allows running scripts written in any .NET language in-game. The issues page should be primarily used for bug reports and focused enhancement ideas. Questions related to GTA V scripting in general, are better off on the Discussions page or in forums dedicated to this purpose. Microsoft Visual C++ Redistributable (Latest supported v14, not v14.0) The stable builds can be downloaded from the Releases page. You need to use the ASI file and the DLL files for APIs in an archive of the same version as the internal structure can be changed without notice. If you are using the game version v1.0.3258.0 or later and installing SHVDN as a user, use the nightly version v3.6.0-nightly.89 or later (see below for nightly version details), or downgrade the game to v1.0.3179.0 or earlier! v3.6.0 and v3.5.1 have a compatibility issue with the game version v1.0.3258.0 and later game versions! For script developers: you should build your scripts against stable versions rather than nightly ones unless you acknowledge that public features that aren't in stable versions can get breaking changes.
