CHIP-8 Emulator

A CHIP-8 emulator written in C++20. CHIP-8 is an interpreted programming language developed in the 1970s for video games.

Features

• Complete CHIP-8 CPU implementation with all standard opcodes
• 4KB memory layout with proper memory mapping
• 64x32 pixel monochrome graphics with XOR drawing
• Built-in hexadecimal font set (0-F)
• 16-key input system
• Delay and sound timers (60Hz)
• Random number generation for RND instruction

Building

mkdir build 
cd build 
cmake ..
cmake --build .

Project Structure

• chip8.h/cpp - Main emulator class with CPU, memory, and I/O
• main.cpp - Entry point (implementation pending)
• games/ - Test ROM files
• CLAUDE.md - Development documentation

Architecture

The emulator implements the standard CHIP-8 specification:

• 4KB RAM (0x000-0xFFF)
• 16 general-purpose registers (V0-VF)
• 16-level stack for subroutines
• Program counter and index register
• 64x32 monochrome display buffer
• Hexadecimal keypad input

Status

Core emulator components are implemented. Audio backend integration is pending but i dont think I'll ever implement it!
