Emulators Written in JavaScript (opens in new tab)

I wrote a Chip-8 emulator (VM?) in C# and then tweaked it so that Bridge.NET could compile it down to JavaScript:

small & easy linux-like in-browser emu: http://bellard.org

fullscreen, "Unix-like virtual shell", u.a. ssh(!?); ping(ok) "-": no c&p, http://cb.vu/

think, there are some more Linux & unix Emulators in js? would be nice, find some in next comments. :-)

Intresting that SNES is missing from the nintendo list. There's a good bit of literature on the underlying implementation for SNES roms: https://github.com/bttf/snes_dev

(Full disclosure: I spent a little time accumulating aforementioned literature)

Can't wait to see some of these ported to WebAssembly.

Missing a TI calculator emulator I wrote in C that can be compiled with emscripten and run in the browser (does that count?):

The title is a tiny bit misleading. Indeed all of those are JavaScript emulators, but not all of them were written in JS. At least one on the list (mupen64plus) is transpiled from C++ using the (amazing) emscripten.

This appears to be ripped from the original list here, which is also more uptodate:

How many of them are proper, accurate emulators though (and not emscriptened ones like mupen64)? Parsing bytes and mapping them to instructions is easy, and I believe that's why most of them are for very simple machines. We're still very far away from having multiple PS1/N64 era that are running at a tolerable framerate.

Except 1964js, which works in a way that both amazes me and makes me feel dirty at the same time.

Also missing a 6502 emulator I wrote in Go that is transpiled to JavaScript using Gopherjs: https://play.dodolabs.io/?code=89e9a475

I would actually be more interested in the ones that are actively maintained. Many tend to come and go, NESBox being one that comes to mind.

Some of these are not emulators, they are just code translated to Javascript, or e.g. compilers written in Javascript.
