The Playstation 2 is my favorite console of all time, and recently I've been setting up a way to play all of my favorite games from 20+ years ago. Using original hardware, the best way to do this is using OPL.
Open PS2 Loader, or OPL, is an interface installed on a PS2 memory card using Free McBoot OS. Through OPL, you can view all games you have installed on a USB drive, hard drive, or on a network share. After a bit of trial and error, I have a tons of a games on a 4tb hard drive hosted on a network share from a Raspberry Pi.
I have loaded this hard drive with every or any game I've ever remotely wanted to play, and the list has grown far greater than I imaged it would. To keep track of everything, I put all the entries in a database. And because OPL uses box art and metadata, I wanted an easy way to view it all.
So, I made another Game Inventory page, and this shows all of the Playstation 1 and Playstation 2 games currently stored on my hard drive.
UPDATE - January 23rd, 2025: The PS2 Game Inventory has expanded to include Dreamcast and Gamecube games. Probably more in the future, too. This has been renamed to the Modded Console Game Inventory, and no longer serves just Playstation games.
