Those who enjoy this might also enjoy "Creating a NES emulator in C++11" [0] [1] [2] while not short in bytes of code(space) there is a nice video series short in minutes(time). Bisqwit takes you on a 30 minute tool assisted coding journey of making an NES emulator and also provides a 15 minute followup Q&A video explaining different aspects. [0] https://www.youtube.com/watch?v=y71lli8MS8s [1] http://youtu.be/XZWw745…

To save you a click, the video is someone speed-typing the source code to an emulator, with no commentary or explanation. You'd probably be better off reading the final result yourself.

They are not actually typing it at all, from the faq https://bisqwit.iki.fi/jutut/kuvat/programming_examples/nese...

  Q) Is the video sped up? Or, is that your real typing speed?
  A) No, it's not sped up. But the input is pre-choreographed. The computer
     implements the choreography, as well as designs a part of it.
     It is a TAS, except I'm not speedrunning; I'm just aiming for
     15 minutes and to utilize it in the most entertaining manner.
     My typing speed is not the focus of that video; it is not even
     being presented except in a small part of the 2/2 video.
     The focus is in the source code.
He actually wrote his own editor that he uses in the video and I believe that assists with the choreography.

Yes, my point wasn't at all about the speed. You can replace "speed-typing" with "displaying at a speed too high to read, much less think about".

Big fan of this author's work.

They have a Gameboy emulator written in C, which can be compiled to WASM and run in the browser.

I learned a lot from the code.

Also I love this project with a bunch of demos in hand-written WebAssembly Text (WAT) format, which is like low-level Lisp that works only with raw memory, numbers, and minimal syntax.

Then I discovered the same author is quite active in the WebAssembly ecosystem, including specs and tooling. Fascinating stuff!

Thanks! I don't work much on WebAssembly anymore, but I'm super excited to see all the progress being made.

Well, 5000 bytes of C++ plus the SDL library.

I guess I agree with the other comments here. The SDL is an abstraction that allows this emulator to be a bit portable. You could target this to some microcontroller with a framebuffer in hardware and then SDL disappears, you write directly to the framebuffer and read the inputs directly from some GPIO.
