While i was exploring the "GENRL" audio files with Alci's SAAT sound extract tool, i found some sounds, which aren't used in GTA San Andreas (now). Sounds were:
Barber Sounds (Scissors)
Train Horn (Not included in the mod! I need a script for it!)
Bike Sounds
Light Truck Sounds
Old Car Sounds (not sure)
UPDATE: AND MUCH MORE FOUND AND REPLACED!

I still search for more sounds in other archives, until the mod process is "finished", so please be patient.

FOR DOWNLOAD, YOU NEED ALL PREVIOUS VERSIONS, BESIDES ALL THE UPDATES, OF IT, ESPECIALLY THE BASIC, THE VERY FIRST VERSION!

All you need is following:
((BACKUP FIRST OF ALL YOUR SA FOLDER FOR SAFETY!))
First of all, you need this:
http://www.gtagarage.com/mods/show.php?id=5777
(be careful with this tool and it's not my fault, if your GTASA gets deleted!)

Then download (ofc) this/my mod to your mod folder or whatever.

Extract Alci's sound tool (best is, you extract the folder into SA folder)

Run the .exe of Alci's sound tool. (if you got problems to start it up, dont worry, just double click then on a file there called "vcredistx86" or something and install it and start again)

Set your SA directory and your Working dircetory (best is, you set the working directory into Alci's Sound tool folder!)

You will see a list in the left witht he sound files, double click on "GENRL" and wait some time. (dont close it!)

After it's done extracting, you will see in your "Working Directory" a file called "GENRL". Replace the folder, with the folder in my mod included.

After done, SAVE it with the Alci's sound tool and wait a second and never try to click "abort" .

Done, start up GTA San Andreas and have fun.
