A simple CHIP8 emulator written in Lua using the LOVE2D library This is my first project using love2d, so the code might be bad. BUT it's still usable.

✨ Features

• Full instruction set - All opcodes implemented, including display drawing and timers
• Graphics - 64×32 black and white display built with love2d
• Sound - Simple beep sound when ST (sound timer) is active
• Input - Hex keypad thats mapped to a keyboard
• Rom loading - Drag and drop a .ch8 rom binary
• Debugging - Window title shows the pc

🎮 Controls

• Key correspondings

1 2 3 4 > 1 2 3 C
Q W E R > 4 5 6 D
A S D F > 7 8 9 E
Z X C V > A 0 B F

• Space Toggle execution
• Drag and Drop → Load a .ch8 binary into the emulator

🚀 Getting Started

Requirements

• LOVE installed on your system

Run the Emulator

Run the emulator from your project directory using love .

Load a ROM

• Drag and drop a .ch8 binary into the window
• The program counter starts at 0x200 (normal chip8 starting point)

Where can i find roms?

• https://github.com/kripod/chip8-roms, alternatively you can use the roms in the "examples" folder.

📖 How It Works

• CPU Cycle - Fetch > Decode > Execute with customizable cycle per frame
• Memory - 4k ram (0x000-0xFFF), fontset loaded at 0x50, roms at 0x200
• Timers - Delay and sound timers clock down at approx 60hz
• Display - Pixels drawn using love.graphics.rectangle()
• Sound - Beeps generated using love.audio.newSource()

⚠️ Limitations

• Code is experimental and garbage (my first love project)
• No built in debugger or disassembler
• Only supports normal chip8 programs
