CHIP-8 Emulator

Graphics are implemented using SDL. All instructions/features are implemented currently (it passes all tests) with the exception of the buzzer, and the clock speed also needs to be tuned.

Here is the emulator running pong:

Setup & usage

Install sdl2 brew install sdl2. Just clone, run make, then ./emu [rom file]. The 4x4 keypad is mapped to the leftmost 4 keys on each row, and ESC exits the emulator.

Debugger

To use the debugger, ncurses is required: sudo apt-get install libncurses5-dev libncursesw5-dev.

For a quick demo of the debugger, use make test.

Debugger in action:

For another means of graphical output, I've wired my Pi to a 128x64 SSD1306 oled display, with each of the 64x32 CHIP-8 pixels scaled up by 4.

I found Cowgod's Chip-8 Technical Reference to be highly useful in implementing this emulator.
