Atari Assembly Tutorial

This repo contains the code for the 6502 Assembly Course from Udemy, taught by Gustavo Pezzi.

Dependencies

The two header files come from the dasm project itself (with all relevant credit due, of course).

Building

Run make in the root of the repo

Running

Run stella -fullscreen 0 target/<name>.bin

Hint: Try this on pride.bin first! ;)

Cleanup

Run make clean to delete all the binaries in the "target" folder. This might seem wasteful, but they're so small and assemble so quickly it really doesn't matter. ¯\(ツ)/¯

TODO

  1. Finish the class
  2. Use this as a testbed for github actions and see if I can get that to play nice 👀
