Hello again!
Chapter 12, "Practical Loops", is now posted on the website. This chapter takes the opcodes and techniques from the last chapter and applies them to the existing code to make things more readable and maintainable. It also includes a homework assignment!
Chapter 12
Next chapter, we'll look at creating background graphics on the NES, and then we'll start making our sprites actually move around on the screen.
Thanks for subscribing! Please send any feedback to kevin@famicom.party.
Wishing you all a happy holiday,

P.S. - If you use a Mac and you updated to the latest MacOS "Catalina", you might have noticed (as I have) that WINE no longer works, due to the removal of 32-bit support. There are a number of potential workarounds, but I am still doing some investigations into what will end up being the simplest for most people. I'll send an update when I have more to share on that front.
