Hey folks.
I did not feel like reading through eight pages of posts just to confirm, but I do not see a Playstation 2 emulator on the list. PCSX2 is an excellent emulator with an easy to customize control scheme. Although I think you would need a more than entry level processor if you want to run these games smoothly.
Accessible games I can think of off the top of my head are Mortal Kombat Deadly Alliance, Tekken 5, Dragonball Z Budakai and then there are a few I am unsure about like Onimusha Blade Warriors, and The Gauntlet Seven Sorrows. I played games on this console when I could still see, so I don't know if all the games can be completed from start to finish.
I also saw that the NVDA OCR can read text in the games in this emulator. The accuracy differs from game to game though. I can think of a few games that might be playable if the OCR can recognize text, like Yu-Gi-OH duelists of the roses which plays yugioh on a board almost like chess. You have to power up your monsters with spell cards and the specific field type grants some monsters advantages or disadvantages. I can't test this though because my copy of this game and all of my other ps2 games in fact, are in a box in my parents' garage. I will get them when I go home again. Maybe Christmas or something. Then I can add some games to the list. The same goes for my ps1 collection and if you have a really powerful PC, or just the console, I will also check out my ps3 collection and add the games.
