Idiot-proof Guide to psx4all
Step 3: Setting the Permissions to 755
For this, you can use either Squid or Finder. I use Squid. Download it from Installer, then open it up. Touch Applications, then find psx4all.app. Touch that, then find psx5all at the bottom. Touch that, and you'll see nine green boxes. Make sure that all of the boxes with Read next to them are checked, same with the ones with Exec next to them. There are also three boxes with Write next to them. Only touch the left-most box, then press Apply. That will set the permissions to 755 and make psx4all work.
Step 4: Putting Games onto your iPoT
Open up WinSCP or TotalCommander and get into your iPoT's files. This time, go down and click on "var". Then click "root", then "Media", then "ROMs", then "PSX". Find the ROM you downloaded on the left column and drag it into the right column. This might take a while, so I highly recommend TotalCommander because it's the fastest way to transfer games. Let it finish, close TotalCommander or WinSCP, then that's all there is to it. Congratulations, you've gotten PSX games on your iPod touch!
