Abandoning this repo. Later courses require drop-in code and assets.
Includes CA65, make, and an extension to highlight 6502 assembler.
After container is built, devcontainer will run get-nes-dependencies.sh which will download headers and macros from CA65 into the ./include/ and ./macros/ directories for the current CA65 version.
makefile looks for main.asm in ./src/ directory and build artifacts to ./out/.
