ReactJS powered multi-system emulator framework, built on modern JavaScript with WebGL

1. Implement a ReactJS and flux-powered pattern.

• Keeps menu components completely separate from the underlying emulator.
• No document.getElementById() and especially no jQuery() should exist inside of emulator code.

2. Use ArrayBuffer with TypedArrays (e.g. Uint8Array).

• Quickly and accurately models memory space.
• Don't << 8 and & 0xFF all over the place - model registers and memory as the type they are, instead.

3. Use modern WebGL, including pixel shaders, to move as much of the graphical heavy lifting.

• This is a big advantage of going in-browser: graceful degradation is easier to implement.
• No need to install 3rd-party rendering libs, either.

4. Speed and playing experience are more important than doing things exactly the same way as the original hardware.

• Dynamic recompiling should be considered upfront, not as an afterthought.
• Even if it's more authentic, jittery background scrolling and maximum tiles per line limits should be avoided in favour of a more modern experience.
• The goal is to provide a performant, enjoyable, modern experience.
