This is a very simple launcher that I made to launch MTA San Andreas using the Steam version of GTA San Andreas.
I've built this mainly to be used on Linux through WINE, but it can be used on Windows just fine. (It's a Windows binary after all..)
NOTE 1: This launcher will replace the original GTA San executable, so make sure to rename it to gta_sa.exe in case you don't have the downgrade patch installed.
NOTE 2: Make sure to install MTA San Andreas in a folder called: "MTA San Andreas" in the GTA San Andreas executable root folder.
e.g: D:/SteamLibrary/steamapps/common/Grand Theft Auto San Andreas/MTA San Andreas
