Things You'll Need
Instructions
Download the latest version of the UlaunchELF CD ISO from the site in Resources. Launch a CD-burning program capable of burning from an ISO image (examples include Nero Burning ROM and Roxio Creator) and choose "Burn From ISO" or "Burn From Disc Image."
Navigate to the UlaunchELF disc ISO in your software's "Select Image" window and double-click the image to select it. Insert a blank CD-R (a DVD-R will not work) into the CD-R drive of your computer. Click "Burn."
Open the lid of your PlayStation 2 Slim and locate the tray sensor ports on the top and bottom-right edges of the circular disc bay. Insert a rolled-up silicone earplug into each port to block the sensors.
Insert the GameShark disc into your PlayStation 2 without closing the disc tray. Turn the system on. Wait for the main menu screen to boot, then remove the disc (watch your fingers as the disc won't stop spinning for you to remove it).
Insert the UlaunchELF disc created in Step 2 into the disc bay of your PlayStation 2 Slim. Select "Run Game Without Cheats" from the GameShark menu to launch UlaunchELF from the disc.
