If you are having issues, do the following:
-Install a fresh copy of GTA San Andreas
-Install the BTTF mini mod version 0.1.3.2
-Install Silent Patch to your GTA SA directory
-Install Silent’s asi loader, overwrite the existing vorbis dll files in your GTA SA directory
Since I found the install script for the SA mod a few days ago on an old hard drive, I may well update it to include Silents patch and asi loader and upload a new version of the installer which is windows 10 compatible.
Edit - updated installer published today, as always it is recommended to install the mod over the top of a fresh/clean install of GTA San Andreas: https://www.bttfhillvalley.co.uk/forum/index.php?/files/file/109-back-to-the-future-sa-mini-mod-0144/
