The 6o6 v1.1 update improves the performance of a 6502-on-6502 virtualization library through efficiency tweaks to addressing modes and zero page access. The project, originally developed decades ago for a KIM-1 emulator, is showcased with a new Apple-1 emulator example that runs on Commodore 64 or Apple II hardware. This release is a technical refinement of a niche retro-computing tool rather than a groundbreaking new development.
Background
The 6502 microprocessor was a foundational 8-bit CPU used in many classic computers like the Apple II, Commodore 64, and the original Apple-1. Emulating these systems on modern or period hardware often involves software virtualization of the CPU.
