#2The dev said in one of the comments to the video:
I used EDK II framework. About the keyboard input, Program reads the value from 0x60 port directly because of multi-key input processing. I measure the timer count twice(for 1sec) by using the rdtsc instruction to make game delay more accurate. I didn't implement the audio output.
One can read in the video that it's a port of MoarNES: https://moarnes.sourceforge.io/ (0.13.8.21 alpha).

>Can we make it so that you pick an OS to boot based on which pipe Mario goes down?
This would be awesome.

I don't know about that, I think targeting a legacy non-UEFI BIOS for this application wouldn't be a lot more work?

that's the point.
I thought it was the opposite of the point, that modern BIOSes had evolved to make this possible, but I think a non-modern legacy BIOS would work just as well. :)
