This is a humble CHIP-8 emulator made as a lazy Sunday project.
Implementation based off of this spec with some slight tweaks for SUPER CHIP. The emulator has been tested against most of the ROMs in https://github.com/Timendus/chip8-test-suite on macOS.
go build .
./c8 -r <your-rom-file>
Help for the program is available using the --h (--help) flag.
By default the emulator uses SDL as the input/output backend. You'll need to have the SDL library installed on your machine in order to compile/run C8.
Alternatively you can use the terminal backend:
./c8 -r <your-rom-file> -b terminal
Since there are no key release events in terminals, they are simulated with a 250ms timeout.
By default the CPU will simulate running at 600Hz, while the rendering will happen at 60Hz.
You can customize both values when launching the program with the -c and -r flags:
-c value, --cpu-rate value The CPU rate in Hz (default: 600)
-r value, --render-rate value The render rate in Hz (default: 60)
