Sony stopped making new PlayStation 2s in 2012, and in a few days the last vestige of support will end: https://www.usgamer.net/articles/ps2-is-finally-dead-18-years-after-release
Given that it's the best selling console of all time and its catalog is extremely significant, it deserves a better preservation effort than it's gotten. I wish PCSX2 were as far along and robust as Dolphin. I wish Sony had bothered with a 100% software back-compat solution for PS3/PS4, and that people in the industry hadn't been so dismissive of that.
PS2 is Finally Dead, 18 Years After Release

Goodnight, sweet prince.

The dismissal of platform-level back compat (ie put a PS2 disc into your PS3/PS4 and it Just Works) always leaned hard on murky platform holder anecdata like "people request this more often than they actually use and value it". And it's like, well you never really offered it for reals so you have no idea what the real demand was.

@jplebreton it's such a bummer because the launch PS3 systems had ps2 hardware in them in NA / JP (I still have one of each, with replaced bluray lasers after the originals wore out).

I think a big part of it has been being able to charge you again for the same old games since supporting any of the emulation BC has non-zero testing and work involved (albeit on microsoft's side, the games that they do support work with discs or digital downloads preserving your old purchases).
