Grand Theft Auto: San Andreas source code.

Hello,

i've been searching around for a way to play videos ingame so i did start my searches on DirectX 9,

but i did found this https://github.com/jte/GTASA my question is, is this real? if it was the real gta sa source code, then this might help us much! (and Kalcor too)

i would like to hear your opinions about this.

EDIT: as i see here https://github.com/jte/GTASA/issues/5 MTA has found way to it.
