    title says all. is it even possible? I think it would run after some optimizations. and it would be even cooler if you could launch them from the home menu

    There is work in getting Dolphin on the Switch.

    I expect given some time, and the right developer's interest it could happen.

    I don't think Dolphin would work on any home consoles, even the Shield TV barely runs Dolphin and only some games run at what I would call playable speeds. The Shield TV is the same hardware as the Switch just 1GB less RAM but with a faster CPU and GPU...

    Comparing the PS4/Xbox One to a PC, what will trip things up again is the CPU speed, the PS4 and Xbox One both use AMD's older CPU/APU things... they kind of suck at IPC and I run Dolphin on an AMD CPU in my living room similar to what would be in the Xbox One or PS4 except mine is 6 cores clocked at near 5Ghz... Dolphin runs great except my PC's CPU is running nearly double the speed of the PS4's CPU and then there is the whole other situation that the APU's used in the home consoles are like cut down versions of the PC CPU's... So even less performance clock for clock.

    GPU wise the consoles do great, in fact for games designed for the systems the CPU is not holding anything back, it's when you try to hit emulation where things get CPU intensive the home consoles really have a weakness.

    In my estimation it could be possible to do Dolphin or PCSX2 on the home consoles, but it's going to be a LOT hard work. I just don't see anything much beyond proof of concept work if it happens at all.

    Somewhere, over there!
    I'm guessing you're referring to the fx series? All of which were severely outdated within 2 years of release? Not to mention you're forgetting the fact that the PS4 and its OS are much more lightweight freeing up headroom for other tasks. Dolphin is definitely possible. Even then you're looking at mid tier performance (at best)

    Oh yeah it's possible, but with out Direct X or Vulcan your left with hand coding a lot of that stuff since your not dealing with "overhead" some of that overhead is super nice drivers and Direct X and Vulcan.

    and yeah FX CPU on my machine that would compare favorably to the CPU in the PS4 "The PS4's CPU is roughly equivalent to an FX8120 underclocked to ~1.8GHz." grabbed that from another web page but it's true. The PS4's CPU is super weak compared to a PC. Windows isn't eating up over 3Ghz of resources by itself on a multi core CPU (I also have more RAM than the PS4 in my machine so it gets worse and worse.)

    My main machine is a Skylake i5 OCed to about 5Ghz my media center PC is an FX 6200 OCed to 5Ghz, 16GB's of RAM on my main machine 10GB's of RAM on the living room machine with 4GB's of GDDR5 VRAM on both of those.

    Sorry it might be possible but your never going to see anything running all that great on it, expect like Shield TV levels of performance on the PS4 in regards to emulation. Many emulators will run perfectly N64 PS1 and feature lots of enhancements if someone can get the ported over correctly. Anything newer than that is going to require herculean levels of work.

    Edit: Basically it all breaks down to this "I'm guessing you're referring to the fx series? All of which were severely outdated within 2 years of release?" Yes except running much slower... If that doesn't put things into perspective in regards to what is possible on the PS4 nothing will.
