"CHIP-8 is an interpreted programming language, developed by Joseph Weisbecker. It was initially used on the COSMAC VIP and Telmac 1800 8-bit microcomputers in the mid-1970s. CHIP-8 programs are run on a CHIP-8 virtual machine. It was made to allow video games to be more easily programmed for these computers." — Wikipedia

I wrote this emulator to get a better understanding for how emulators work. The emulator uses OpenTK for rendering and keyboard input. Keyboard keys 0–9, A–F maps to the corresponding chip8 keys.
