Introduction

Chip-8 is an interpretted language designed to create programs/games on the 8bit systems like the COSMAC VIP and Telmac 1800. Chyp8 is an emulator of the Chip-8 system build with Golang. For more info on Chip-8 refer here

To build Chyp8:

Clone the master branch and use go run main.go start roms/NAME_OF_THE_ROM -r=REFRESHRATE or run the .exe file in command line as ./main.exe start roms/NAME_OF_THE_ROM -r=REFRESHRATE. The -r=REFRESHRATE argument is an optional flag which sets the clock cycle of the emulator. It's set to 60 by default.

To Use Chyp8 (without building it):

Get the tar.gz or zip folder downloaded from the Releases according to your OS and run ./main.exe start roms/NAME_OF_THE_ROM -r=REFRESHRATE in a terminal.
