Great idea, but the performance is very poor for me. The games skip frames all the time, almost like a slideshow. I've only tested it locally, by the way.

(Windows 10, Chrome, i7-7700, GTX 1050.)

What emulator did you use for this? (I would suggest using DuckStation, it's a million times faster than any other and more compatible than most of them, only Mednafen may work better in a few games.)
