[Matheusroque]

how i can do to extract only the maps of gta sa united ?for example, i extract the img files of the vc and III maps and the data files, and install on gta sa, because if me install the full mod, it will remove all my other mods, so i just want to extract the map files and the img files and the vehicles and peds paths to the vice city map and III map, how i can do ? or someone can do it for me !
