Not a stupid question at all :) the steam deck can emulate games a mid-spec modern gaming computer can handle, I’ve had good performance with up to PS2 titles, but I have never tried PS3 or Xbox 360.

I think Emudeck includes RPCS3, a PS3 emulator. It could be worth trying, for sure, but I’d expect it to stutter a bit :)

if it doesn’t run in RPCS3 on a computer the steam deck won’t be any different, it’s essentially just a gaming PC that boots into big picture mode after all :)

It’s such a great way to play CloneHero, ReTHAWed, and emulators in the livingroom. The Switch really nailed the portable to docked mindset, but steam deck brought the real capabilities
