-Each day is written into its own file inside of `src`. Build everything by just
-calling `make` and you will get a `.nes` file per day inside of the `out`
-directory. Before doing that, though, you will need a compiler for the 6052
-platform. A good option is [cc65](https://github.com/cc65/cc65), which is

 After that, it's recommended that you run the ROMs with an emulator with
 debugging support or at least some form of memory visualization. This is because
