-JavaScript GameBoy Color Emulator
-=================================
+APU
+===
 
-**Copyright (C) 2010 - 2016 Grant Galitz**
+Want some hardware-accurate Gameboy music and sounds in your HTML5 game or app? Don't want to load megabytes of .mp3 files? [Overwhelmed or frustrated](https://blog.mecheye.net/2017/09/i-dont-know-who-the-web-audio-api-is-designed-for/) by the Web Audio API? Welcome to **apu**!
 
-A GameBoy Color emulator that utilizes HTML5 canvas and JavaScript audio APIs to provide a full emulation of the console.

+* Tiny; single .js file, about 9 kB (gzip)
+* Supports playing .vgm files (which are typically a few kB after gzip)
+* Mute BGM channels while playing SFX
+* Highly performant
+* * Fast sample generation in WebAssembly
+* * When possible, uses AudioWorklet to run completely outside the main thread (works in latest Chrome and FireFox)
+* UMD module; works as script tag, AMD module, in webpack, etc
+* TypeScript bindings

+Browser support
+---------------
 
-Known browsers to work well in:
--------------------------------
+Latest Chrome, Safari, Firefox
 
-* Firefox 4-27 (Windows 7, Windows Vista, Mac OS X)
-* Google Chrome 18+
-* Safari 5.1.5+
 
-Browsers that suck at performance or fail to run the code correctly:
---------------------------------------------------------------------
+Developing
+----------
 
-* Firefox 4+ (*nix versions of Firefox have audio lockup bugs) - Retest this
-* Firefox 28+ (Web Audio API creates 500 ms or greater latency, forced by Firefox)
-* Opera (Crashes + Slow + Graphics Glitches) - Retest this
-* Safari 5.1.X (Below 5.1.5) (Slow or crashes)
-* IE 1-8 (Cannot run)
-* IE 9-10 (Slow, No native audio support (Requires flash bridge in the audio lib))
-* IE 11 (No native audio support (Requires flash bridge in the audio lib))
-* Firefox 1-3.6 (Slow)
-* ALL VERSIONS OF MOBILE SAFARI AND OPERA (Stop pestering me, iOS just **CAN'T** run this well.)
+To develop this project you'll need:
 
-CPU instruction set accuracy test results (Blargg's cpu_instrs.gb test ROM):
------------------------------------------------------
+* Unix system (MacOS and Ubuntu definitely work)
+* Node 12+ (older versions may work but untested)
+* Make
+* Clang
+* LLVM 8+ (should include wasm-ld; or, on Ubuntu 20.04, wasm-ld-10)
+* Binaryen (should include wasm-opt)
 
-* **GameBoy Online:**
+To build it:
+```sh
+make
+```
 
-	![GameBoy Online (This emulator)](http://i.imgur.com/ivs7F.png "Passes")
-* **Visual Boy Advance 1.7.2:**
+To watch & rebuild:
+```sh
+npm run watch
+```
 
-	![Visual Boy Advance 1.7.2](http://i.imgur.com/NYnYu.png "Fails")
-* **KiGB:**
+To watch, rebuild, and run a live-updating web server:
+```sh
+npm start
+```
 
-	![KiGB](http://i.imgur.com/eYHDH.png "Fails")
-* **Gambatte:**
+Troubleshooting:
 
-	![Gambatte](http://i.imgur.com/vGHFz.png "Passes")
+* On Mac, when installing llvm through Brew, you might find that wasm-ld is still not available. Try `brew link --force llvm`
+
+
+Acknowledgments
+---------------
+
+The high-performance WebAssembly bundle for emulating the GameBoy's APU is compiled from C code that was adapted from
+an old version of VGMPlay, which was written by Anthony Kruize in 2002. Without that code, this module would not be
+nearly as performant nor as accurate as it is today.
