From Multi Theft Auto: Wiki

This page outlines some of the places Grand Theft Auto San Andreas can be bought and played with MTA:SA (sometimes with an automatic downgrade step).

Compatibility

Not all of the GTA versions listed below have been tested, but all should work correctly. If not, try reinstalling MTA. If that doesn't work, follow these instructions. If that still doesn't work, then please contact us on on the forums, or join the MTA Discord #help-support channel.
