My Chip-8 Emulator. Works quite nicely.

Written in C++11 (possibly some C++14), feel free to join development!

• Can run any valid Chip-8 roms (.ch8 files).
• Emulator can be hard reset.
• Working buzzer (audio) support.
• Configurable
• ... and many more features to come!

• Somewhat working GUI (inside the emulator, software rendered).
• Strongly configurable (volume, keyboard mapping, foreground render color, etc.)

Breakout!

Bowling!

Syntax: ./Chip-8\ Emu <rom.ch8>

The emulator expects the dotfile .chip8_pref to be found at it's binary location. This is a JSON file, storing the emulator preferences.

Here is a sample .chip8_pref file, listing all existing settings:

{                //   xxrrggbb
  "RenderDrawColor": "FFFFFFFF",  // XXRRGGBB
  "RenderClearColor": "FFAA0000", // XXRRGGBB
  "Volume": 0.5,                  // Buzzer volume (0.0 - 1.0)
  "Resizable": true,              // Is the window resizable?
  "Width": 960,                   // The window width.
  "Height": 480,                  // The window height.
  "Ticks": 8                      // How many Chip-8 processor ticks per frame (1 - 999999).
}

All these settings listed are optional, the emulator has hard-coded defaults.
