The most simple emulator to write. All opcodes are implemented following this reference, sound and graphics I/O work via SDL. Running make test uses this awesome ROM to test a bunch of instructions at once.
The only dependencies are gcc, make and SDL2. You should probably have those. If there is no assets/beep.wav, the interpreter will complain once and simply not play any sound effects.

make testChip-8 accepts input from keys 0 - 9, a, b, c, d, e, f. A few other keys instruct the interpreter to do things that aren't part of Chip-8 but are useful:
| Key | Action |
|---|---|
h/r |
halt/resume the emulator |
n |
when halted, run the next instruction only |
i |
display machine state information |
up/down |
increase/decrease CPU clock speed |
