WebAssembly / AssemblyScript Atari 2600 Emulator
I've been fascinated with the 2600 ever since reading Racing the Beam, the idea of a computer that doesn't have enough memory to support video RAM is just nuts! This project is an excuse to have a play with AssemblyScript, and explore the 2600 further.
I'm implementing the 2600 by implementing features as they appear in the Atari 2600 Programming for Newbies guide.
