Need help whats wrong? in GTASA Modding Posted August 29, 2010 I install the mods like .dff and .txd I extract to back them up first. (IMG tool) I replace with new files I rebuild the archive and it doesn't change the mods to the new ones. The only mods that work is when I install mods with SAMI. Is something wrong with IMG tool or what? Been doing this for a while Thanks.
