i understand a lot of this tech because of my work on my #mega68k fantasy console (which is basically an emulator for a system that didn't exist) and my experiments with programming language development. the principles involved aren't that complex, but getting all the myriad little details right as well as rolling it all up into a nice easy to use package ready for distribution requires a ton of dedication and is a seriously impressive achievement
