As you you might have noticed, epsxe isn't beetle psx. Even if you cant spell it.
As you might have googled, epsxe is a closed source project and cant be ported.
As you might have looked up the switches CPU runs at 1Ghz in portable and in docked mode, which isnt very much when it comes to emulation of 3D systems. Its especially not enough for beetle psx.
You see everything can be explained with logic. No "bu, bu, but why?!" needed.
PSX emulation currently is at around 52-60 fps in most games, so people are playing with the concept of overclocking the cpu to even get psx rearmed full speed on ntsc games (some are, in some, a framedrop of 4 frames isnt the world, and you can always play pal versions (which run at 50hz) if you must) -- the only performance increases that would be possible without overclocking at this stage would come from a dynarec (dynamic recompiler), which isnt readily available, because the switch is a 64bit arm system, and your phone probably is a 32bit arm cpu. Different architecture. You could also start writing emulators in assembly, but then you need those Rainman style autistic sauvants to do it, that never are readily available, when you need them (movie was from an aera, when people where interested in actual plot development, so you can watch it - even as a mil...).).
Thats the part that tells you that people are already doing everything they can and thats possible. Its certainly not because of a lack of trying.
