Mono square wave sound using SDL audio with a callback function, lerping between foreground and background colors in a (failed?) attempt to reduce flickering, and more emulator keybinds.
There is at least 1 more video for this; I found a better test suite rom and want to fix some instructions, and separate original CHIP-8 from SUPERCHIP "quirks" a bit better.
