This is the first N64 emulator written in JavaScript. It is loosely a port of our N64 emulator for Windows called 1964. 1964 was written in C and C++.
Compatible with Google Chrome and Firefox. Chrome is preferred because it will run 1964js faster.
This project is still in the early stages. The initial goal of this project was to see how well Google Chrome´s V8 JavaScript compiler performs.
I don´t have benchmarks yet but the results look good.
Pip´s World Game 1 by Mr. Pips:

Instead of building a traditional dynarec (JIT compiler) as we did for 1964 for Windows which translated MIPS directly to x86, 1964js dynamically writes JavaScript to the web page by reversing MIPS code to JavaScript. This JavaScript represents blocks of rom code. Then, if using Chrome, Google´s V8 compiler compiles the JavaScript to native code for us automatically.
