I've just made a little mod that replace default menu of SA. It's like a bonus files to HD Universe GTA Vehicles pack. Also it has new interface and menu sounds from GTA IV and GTA V.

It has 2 versions:
1. Classic - pictures in a upper right corner like classic game has.
2. Fullscreen - I think everything is clear here)

So if you wanna see something new when you start the game - you can download it)

UPDATED:
- New replacement for interface and menu sounds from GTA IV&V were included to archive.

Thanks to Astitva Vimal, I used some ideas for sounds from his mod.
