Simple CHIP-8 emulator written in C++ using SDL2 for monochrome graphics. This emulator is not perfect in terms of code or working, but it can run simple games and programs.

Features

• Full CHIP-8 CPU instructions
• 64x32 pixel display
• Keypad input mapped to PC
• Load ROMs
• Debug output for opcode execution

Build

Requirements: CMake (>=3.31), SDL2, development libs

git clone https://github.com/Doonort3/CHIP-8-emulator/
cd CHIP-8-emulator
mkdir build && cd build
cmake ..
make

For Windows, replace usleep (posix) with sleep (chrono) in main.cpp (114) or just use wsl

Using

./CHIP_8_emulator ../programs/<ROM>
