You must have played NES or SEGA games on your pc at one time another. I remember when i used to spend many hours on my pc playing Nintendo 64 games or Gameboy Advance games. And now it is possible to play games for PS2 on pc using emulator called PCSX2. There is a limitation though as Playstation 2 has much better graphics compared to gameboy advance or NES, so your computer needs to be powerful to play games at proper speed with good graphics. Here is a rough indication of the recommended specifications:
- Windows XP or Windows Vista
- Core 2 Duo Processor 2 Ghz or better
- 1GB RAM (2GB for vista)
- 512MB Graphics Card (8600GT or better)
You can download the emulator from here. The emulator doesn’t support 4 cores so the results wont differentiate too much between 2 cores and 4 cores. The emulator is able to play many games properly but there are still many games which are not fully playable. You should check the Compatibility list for your desired game to see if it can be played properly to the end. Probably the most hardest thing to do is to configure your PCSX2 Emulator but luckily for us, there is a very nice guide that can help you with each step.
Also, while configuring your emulator, you will need bios for ps2. You can only get them legally from your own ps2 although you can find them on torrents as well. Search for them. I cannot provide them. You may also want to read the information on the PCSX2 forums to fully maximize your playing experience. I have tried a couple of games on my computer and they worked quite well although you really need to have a gamepad connected to your pc to enjoy playing the games.
If you have any questions, just leave a comment here and I will try to help you, or you can try the PCSX2 forums where many people with greater knowledge of the emulator will assist you readily!
