gta2 help please

[wite warrior]

okay hi, im not a newbie to dc burning but it has been a while since I last made a game and I started to want to play some gta2 so I got my .cdi file and its unrared, i have all the tools like fireburner and DJ and when I used DJ i got a cd with only a sound file, I forgot what I was supposed to do...I think I was supposed to inject something maybe? So if someone could please help my memory loss I would really apreciate it, thanks.
