Play Copied PlayStation Games Without a Modchip

This guide should help you to play your copied/burned PlayStation games without a Modchip.

Steps

Find the PlayStation game that you want to make a copy of. You may find it in your old game collection, on e-bay, or from your friend's or family's games. It doesn’t matter; just get yourself a game.
Burn a CD of your chosen Playstation game.
Open the lid on your PlayStation One. Locate the clips which keep the lid shut. Put a piece of electrical tape on the button below the clip on the inside of the PlayStation so the PlayStation will spin while the lid is open. After you place the tape, when you open the lid the tape should be stuck in the button, holding it down.
Put in the original game disc, and turn on your PlayStation with the lid open. After the game loads to the second black screen, listen for the sound of the PlayStation reading the disc(The disc speed will slow down and then speed up again).
After it’s done reading, wait a second, and switch the disc with your copy disc. Wait for it to finish reading, then switch your copied disc back with your original disk.
Be prepared with your copied disk in hand. As soon as the screen switches to the next screen, put in your copied CD and it should load up.

Handle your games with care when switching them to keep them in top shape.
This is a trial-and-error process, so don’t expect to get your game working the first time.
This can get very frustrating the first few times because you won’t get the timings right. Whatever you do, don’t give up!
