Things You'll Need
Instructions
Go to the iPlayPlayStation website to download the uLaunchELF ISO file. This is the image file of the uLaunchELF CD that will allow you to play homebrew games from a USB drive.
Use your CD burning software to burn the uLaunchELF disc. You will want to convert the ISO file into a readable disc. Look for an option on your CD burning software such as "Burn Image File" or "Burn ISO File."
Insert the uLaunchELF CD and the USB flash drive that contains the homebrew software into your PlayStation2 and turn on the console. You should see the PlayStation logo flash for a moment before the uLaunchELF menu displays.
Navigate to the "MASS" flash drive option. This will display a list of contents on your flash drive, including the homebrew games.
Launch and play the homebrew games from the USB drive.
