The Art of Chip-8
Summary
The Art of CHIP-8 provides a historical and practical study of the CHIP-8 instruction set, its memory model, and how modern tooling and assemblers (like Octo) approach portability and standardization. It covers system architecture, arithmetic and memory operations, subroutines, control flow, I/O, timing, and rendering, emphasizing cross-interpreter quirks and the value of test suites for emulator correctness. The piece also offers actionable guidance for building portable CHIP-8 programs and emulators, including macro usage and self-modifying techniques.
