The PCSX2 project has been running for more than ten years. Past versions could only run a few public domain game demos, but newer versions can run most games at full speed, including popular titles ...
In fact, it's inching ever closer to that record every month and a former Sony executive now reckons it can actually overtake the PS2 - as long as the Nintendo Switch 2 doesn't get in the way.
Note - Repacks are compressed versions of games that exchange smaller downloads for longer installation times. Good if you have low bandwidth or data limits.
