An unofficial PlayStation 2 emulator has recently appeared on the Xbox Store. It's free to try and play, although we don't necessarily condone doing it on the grounds that piracy is, you know, illegal and could actually land you in jail.
The "good" news is that you can't exactly access the PS2 emulator normally. So, unless you know what you're doing, the PS2 emulator won't be available for you to see. Instead, the individuals responsible for the upload hid the emulator using a special format to prevent the Xbox store from otherwise banning it.
The reason for this is simple: Microsoft does not condone the presence of emulators on its store, let alone a competitor's console. Sony's PlayStation 2 is the best-selling game console of all time, with the company selling over 155 million units during the PS2's lifetime. It came out in 2000 and production didn't end until 2013.
With over 1.5 billion copies sold of over 4,000 games, the PS2 is an iconic console that will reign atop the record books for a long while. Case in point, Sony effectively retired the PS4 at 117.2 million units. The closest unit that has a remote chance of catching up to the PS2 sales record is the Nintendo Switch at 111.08 million units but even that is a stretch.
