MTA:SA setup

Using GTA mods with MTA

MTA expects a clean GTA San Andreas. Single-player mods in the game folder can stop MTA starting, make it crash, or get you kicked from servers that check game files.

Steps

Try one step, then check whether the problem is still there. Follow any "only if" line before changing a setting.

  1. Keep one clean GTA for MTA

    MTA's manual says to install MTA over a GTA San Andreas with no modifications. If you want to keep single-player mods, install the game a second time in another folder and point MTA at the clean one.

  2. Take plugins out of the GTA folder

    Remove .asi files and any d3d9.dll from the GTA San Andreas folder. MTA's guides list both as things to remove when MTA will not start. Mods such as ENB use a custom d3d9.dll, and a server can also block that file (the anti-cheat guide lists it as SD #12).

  3. Changed data files

    By default you cannot join a server with customized GTA data files. If yours are changed, MTA shows a box in Settings, Multiplayer called Use customized GTA:SA files. The guide warns that ticking it keeps you out of most public servers.

  4. Changed gta3.img

    A server can refuse a non-standard gta3.img or gta_int.img. The anti-cheat guide lists that server option as SD #20.

  5. Crashes when you connect

    If MTA crashes on connecting to any server while single-player runs fine, the MTA FAQ points at single-player mods and says to use a clean GTA installation.

  6. On CIT: use /mods

    CIT has its own Modifications window. Type /mods to open it. It has Vehicles, Weapons, Weapon Sounds, Crosshairs and Weapon Skins tabs for the mods CIT offers.

Worth knowing

MTA can set a custom d3d9.dll aside by itself. In May 2022 a player reported on MTA's forum that MTA had renamed the ENB d3d9.dll to d3d9.dll.bak after an update. A moderator answered with a newer MTA build and renaming the file back.

Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
