6502 CPU Emulator

A C++ implementation of a 6502 CPU emulator.

Prerequisites

• CMake (version 3.10 or higher)
• C++ compiler with C++17 support
  • GCC 7 or higher
  • Clang 5 or higher
  • MSVC 2017 or higher

Building the Project

Using CMake (Recommended)

1. Create a build directory:

mkdir build
cd build

2. Generate build files:

cmake ..

3. Build the project:

cmake --build .

Build Options

• To build in Debug mode:

cmake -DCMAKE_BUILD_TYPE=Debug ..

• To treat warnings as errors:

cmake -DWARNINGS_AS_ERRORS=ON ..

Running the Program

After building, the executable will be created in your build directory. You can run it with:

./6502cpu

Project Structure

• main.cpp - Main program entry point
• CPU65C02.h - CPU class declaration
• CPU65C02.cpp - CPU class implementation
• CMakeLists.txt - CMake build configuration

Features

• Implements basic 6502 CPU instructions
• Supports various addressing modes
• Memory management
• Register operations
• Status flag handling

Introduction

This project is an emulator for the 6502 microprocessor. It is written in C++ and is designed to be easy to understand and modify.

The project is inspired by Ben Eater's 6502 tutorial. The final goal is to create a fully functional emulator that can run any 6502 program.

How to run

g++ main.cpp -o main
./main

Add -DDEBUG to the command line to enable debug mode. Add -DSINGLE_STEP to the command line to enable single step mode.

g++ main.cpp -o main -DDEBUG -DSINGLE_STEP
