Sample chip-8 emulator written in Go.
Video/Keyboard handling is done by using the amazing raylib library.
In order to run the emulator locally on Windows, we embedded the raylib.dll file inside the root path of this project. That's the only dependency besides go >= 1.22 to run the project (CGO is not needed).
Inside the test-roms folder there are many public Chip-8 Roms available from the internet, to run one of this ROMs just open a command prompt and type:
go run main.go -f test-roms\$ROM_NAME
ESC: Quits the emulator
The chip-8 keyboard mapping was taken from here.

I wouldn't be able to to this this work without the help of many other emulator developers, so here's the list of references I used:
