Instead of going to bed I set up a PSX emulator on my Steam Deck because someone said that version of Final Fantasy VII is much better than the PC one. It does indeed look prettier thanks to CRT filters, but also my save game has vanished and it crashes when using magic, so not a complete success yet.
I will say it always impresses me when I want to do something like this on the Deck and I can just plug my USB-C dock in and drop down into a fully functional KDE environment at my desk to set it up.
