Leo, do you have a GTAIII "data" folder and "models" folder and "audio" folder and "anim" folder etc.? If you do then you can copy all the folders and the Mss32.dll file to a new location. ( for example "Program Files/Rockstar Games/GTAIII" ) Then use a 1.0 or 1.1 retail no-cd hacked exe from gamecopyworld.
