Things You'll Need
Instructions
Turn on your Sony Playstation2 and insert your HDLoader disk into the PS2 disk drive. Because the HDLoader disk is pressed in the same manner as original PS2 disks, the PS2 will be able to load the disk easily.
Select the disk from the PS2 menu and wait for HDLoader to boot up. Select "Install" from the HDLoader menu and HDLoader will ask you to remove the HDLoader disk and insert your game disk. Insert the PS1 game disk. Installation will start when the PS2 begins to read the disk.
Wait as HDLoader completes the backup. It will notify you when the process is complete. Remove the disk and select the game from the list that appears. Your game will begin to play.
