Hi, I was wondering if theres any difference when extracting roms from it's WinRar Zip Archive. When I extraced the Roms for Grid I have 8 files inside the file I just extracted and there all WinRar Zip Archive files. If I extract those I get the Grids rom. But my question is if theres any difference, becuase theres 8 files and some of them have different sizes than other. Another game thats like this is Final Fantasy Crystal Chronicles Rings.
