For people who enjoy seeing improvements for emulation on Linux, and for Wayland support - the Playstation 2 Emulator PCSX2 has now enabled support for it by default.
EmulationStation Desktop Edition 3.0 is out now and it's gone through a rebrand to simply ES-DE, plus a whole bunch of improvements come with this release.
The quest for better emulation is never quite done, it seems. The open source PS2 emulator saw its first major stable release in years a few months ago and since then more exciting stuff has been under development.
