It seems nobody can make backup of GT4 becuase of few reasons, one of which is original game is on DL DVD. If so, then how is PS2 able to read it. Is ps2 capable of reading DL media? don't u need special hardware that is capable of reading DL medias? When it cmes to making back-up you need DL reader/writter but do you honestly believe that ps2 can read Dl games? How does DL worh anyways? DOn't u need 2 laser beams?
