6502-processor

Your Apple II Swiss Army knife: Apple II family emulator, 6502/65C02 assembler, and disk manager, all in one Windows app.

🚀 Build robust microservices with resilience patterns, chaos engineering, and full observability for enterprise-grade distributed systems.

KiCad-drawn logical scheme simulator.

6502 based computer

An NES emulator written in Go.

A small programming language for MOS6502 (SmartyKit/Apple1)

A Nintendo Entertainment System (NES) emulator written in C++20. It features a custom 6502 CPU core that passes standard functional tests, a Picture Processing Unit (PPU) with DMA support, and a graphical debugger built with Qt for live inspection of memory and registers of the CPU. PPU and APU are still a WIP.

A clock-accurate FPGA clone of the NMOs processor 6502, created on the basis of reverse engineering.

A small daughterboard adapter that replaces a 6502 processor (used in vintage 8-bit computers such as the VIC-20, Apple II and BBC Micro) with a modern equivalent. Two versions are provided, which fit different motherboards.

Cycle-exact 6502/65C02 CPU emulator core with a stable C ABI and bindings for C++, C#, Java, Python, Rust, JavaScript and WebAssembly.

Emulator of MOS6502 (and eventually NES) with particular focus on understandable design and testing.
