Well, i used to do modding, but i did it by:
1) Installing two different vice city's (one in one folder, the other - in another folder)
2) Installing VC-MP in one of the both (the one i'm not going to mod tho)
3) Modding the other one (the one VC-MP is not installed)
That way i can have fun with mods without getting in trouble
But that was old times, i'm done with mods. Now i only use a weapon sound pack which is AWESOME, DUDE!!! YOU GUYS SHOULD TOTALY TRY IT!!! Took me some time to install it tho (since it was my first time installing sounds)
I request something from you tmavs: Could you give me the sound files name's list? (sfx001 - sound of what?, sfx002, etc.)
