Hello! Follow this tutorial on how to install PCXS2. It's a PS2 emulator that you can run on your PC. Once you download the emulator, you can download the MC3 iso file and play it.

Keep in mind that you must have a decent enough PC to emulate it. Emulation may not be 100% smooth like playing on a PS2 or on a jailbroken PS3. But if you don't have a console you should definitely try out emulation.
