olcNES is a Nintendo Entertainment System (NES) emulator written in C++ by OneLoneCoder, built as companion code for a tutorial video series. It implements the NES hardware including the 6502 CPU, PPU, and cartridge mappers.
Use cases
- emulate NES games on my computer
- learn how an emulator works internally
- study 6502 CPU and PPU emulation in C++
- follow a tutorial building an NES emulator from scratch
- run classic NES ROMs
When to choose
- you want readable, educational emulator source code
- you're learning low-level emulation concepts like CPU/PPU timing and memory mapping
- you want a compact C++ NES emulator to hack on
When to avoid
- you need a production-grade, high-accuracy NES emulator for serious play
- you need a license beyond the restrictive OLC-3 for commercial use
- you need active development or community support
