Installation:
Put .DAT and SD in GTA San Andreas User Files directory

Bug:
After the cop finds the body, dialogs of the guy who starts shooting donÂ’t appear, I don't know why that happens.

Explanation of this part of story:
Actually that guy thinks that cop is referring to him when he says crime has been committed so he says I didnÂ’t do anything and starts shooting at the police officer

Note:
You'll need audio or you won't understand 50% of the story.
I am not saying that you'll understand 100% of it with sound but you'll get 75% of what happened...I think
I won't blame you I you don't understand any of it :)
