i have visited Los Santos from GTA V , LC / Liberty City from GTA IV San Andreas from GTA SA Vice City from GTA VC and the older version of LC from GTA 3.
@p3l3r did you use modloader to install the mod? if not better do that.
download modloader from here http://www.gtagarage.com/mods/show.php?id=25377 and put folders in the archive to modloader/audio
the mod must work perfectly with no issues.
btw it should not crash at all even when you've installed the sounds with SAAT. unless you did something wrong.
check how you installed the mod.
@The Last Gamer 154 It does only replace textures of the existing interior and does not add any new objects i tried to add some objects into this interior though that it could have had new tv new sofa and even a laptop in there but the tool i was using caused some bugs to appear into the interior such as misplacing the items after i had placed them making me completley unable to change stuff's placement in the interior cause the map editor tool i was using is still beta, but this mod still cleans up the interior as much as possible and makes it look pretty.
