My ipod touch has the PSX emulator and the bin file in it that plays the roms like ISO and whatever. The .Z file is not working at all. Is it because I need to unzip it because zip files to end with just Z. People really need a great tutorial on this because of the fact that thousands and thousands of people around the world have this issue of file extension and no one knows exactly what to do with this .Z file at all. Ironically this isnt suppose to happen because of the fact that know one knows how to put a "GREAT" tutorial in this website.Now I am asking a big favor on what to do with the .Z file if it cant even be extracted because of the error code and the fact that it says that its damaged but its not.
