Been wanting to record and upload this for a while now and finally got around to doing it.
The following two videos come from the exact same recorded footage, but the first video is at native resolution (well, 400% nearest neighbor) while the second has some super-fancy upscaling (feedback is welcome) that took me a bit longer than 2 seconds per frame to render with GPU acceleration (4 seconds per frame without GPU acceleration).

I give full permission to link and repost this/these video/s anywhere else on the internet without even giving me credit (like on /r/emulation or whatever, I don't care); just make sure you don't claim that you made the video/s yourself.

Oh, and since the forum doesn't show YouTube thumbnails, hare are two screenshots from the video/s of the exact same frame, one at native resolution and the other upscaled:
