Simple Chip-8

CHIP-8 Emulator (Interpreter) written in C++ with SDL3.
Built to be as reasonably modular as possible.
This time actually complete (hopefully).

Build

Requires SDL3 Libraries to be installed on the system

Using Meson

#From Root Directory
meson setup build
cd build
meson compile

Compile using g++

g++ -std=c++20 -O2 -lSDL3 src/*.cpp -o chip8

(not tested with -O3, but should work)

Usage

chip8 --rom <path_to_rom>

TODOs

• Implement Opcodes
• Drawing Graphics
• Implement Delay Timer and Sound Timer
• Sound Timer Beep
• Input Handling
• Error Handling and Logging
• Separate Threads for Timers

Additional Features

• Variable Resolution
• Config File
• Configurable keybindings
• Better Frame Timing Management
• Debug Mode

Test ROMs

• Timendus’ Chip8 Splash Screen
• IBM Logo
• Corax+ Opcode Test
• Flags Test
• Quirks Test (CHIP8 Only)

Planning to add SUPER CHIP-8 capabilites after adding bells and whistles.
