Tried Yuzu and got it to work. Seems like some games run like shit but others are near perfect. Arms is near perfect, Astral Chain is horrible with stuttering and BOTW somewhere inbetween, it clearly dips more than on the Switch and more often and does stutter here and there, but then occasionally it's perfectly fine too (I guess this is why people seem to recommend emulating the WiiU version of BOTW, it's apparently better for it). I guess some of it is my PC and much of it the actual emu still needing work. People are nuts (and/or lying sods) to propose playing in emulators by default as often done. I checked the compatibility list and only a small fraction of the library is listed as "perfect", a bit more of it as "great" (but Mario Odyssey is listed as great like Arms yet is pretty bad on my end, not just performance wise but graphically the first world is completely wrong) then "good" and much of it untested etc. I cba with the hassle compared to emulated older systems either, I think. You have to source the base game, DLC and updates, have to fake install the DLC and updates to the nand, stuff like that. It needs to build a shader cache and the nand with the fake installs and all that stuff seem to go to the default roaming folder, not where you keep the main emulator files, roms and whatever else and that takes space from my Windows SSD. Also some times on first run it went in slow motion but highlighting something else then going back to the emulator or similar fixed that. So, yeah, I really want a Switch (2), but its prospects are natrually very nice for preservation with emulators already in this state (then again, even the renowned Dolphin still has bad issues as I wrote earlier, I thought it's better). Arms (and Twintelle) is
Edit: tried Ryujinx as well, more or less the same experience. BOTW runs way worse even after repeating the intro stuff after it built the shader cache (I guess it doesn't have async shaders yet hence people trying to find predone shader caches which is another exercise in frustration to find up to date compatible ones).
Also, wtf, all this time (not really looking into it since ideally I will play it some day) I thought, to my dismay, BOTW had done away with the series now trademark lock-on battling but apparently it's very much how it is, with all the additions on top. I have no idea what made me think so but I'm sure I had read stuff like that.
