Compiling Super Mario Bros.

To compile assembly code for the NES's 6502 processor, you'll need the cc65 toolchain. That will provide the ca65 compiler and ld65 linker used by these scripts.

On Mac you can install cc65 using Homebrew:

$ brew install cc65

	⏺ Let me check the current state of the foobar repo before changing its visibility.

	⏺ Let me explore the project structure to understand how the code is organized.

	ChatGPT prompt:
	Create a simple app that resides entirely in a single .html file. It should
	take three images from browser storage and animate them bouncing around the
	screen. Each of the three images should have a distinct sound, also loaded
	from browser storage, that plays when it bounces.

	Refinement (because ChatGPT didn't use localStorage like it should have):
	When the user selects an image or sound file, store it in browser storage
	using "window.localStorage.setItem". When the page loads, load images using

	We are a hackerspace/makerspace! We're a community workshop where people can come to create prototypes, art, and projects.
	We are primarily supported by donations of time and money, and member dues.
	During open hours, the public can join us entirely free of charge. But donations are appreciated!
	Check our calendar at https://heatsynclabs.org for upcoming events!
	We have no paid staff, but our volunteer hosts can answer your questions! Every open hours has a host. If you don't know who today's host is, ask around!
	Our discussion board is on Google Groups. The link is on our site at https://heatsynclabs.org
	We use the Slack app for chat. The link is on our site at https://heatsynclabs.org
	Our tools, our workbenches, our wi-fi... Everything starts out a volunteer seeing something the lab needs, and making it happen!
	HeatSync has to pay rent for this space. Your donations help!
	Our volunteers run classes and workshops! Check the calendar at https://heatsynclabs.org
