Are mobile emulators accepted? Following the same rules as the others, audible sound, etc?

I'll be honest I know nothing about mobile emulators. From what I have heard from another mod who knows these things that they are slow and drop frames. If it shows that it's accurate and runs well as mGBA or BizHawk with the mGBA core, then it should be fine. Is there any way you could show a video of this?

Most mobile emulators don't show the framerate. Maybe i could show a vid about.
