Hi Score MK 1 is an Atari 2600 clone supposedly released in Austrailia in an unknown year by an unknown company. The console takes the design of the original Famicom, but in white thus making it have a famiclone look to it. It comes with 2 controllers with a D-pad, & 1 button along with a cartridge that has a label that says, "HIGH SCORE" on top. The console also has 5 switches on it which is most likely put their to not just be more compatible with the system it's cloning, but also most likely to switch games on this cartridge(I'm speculating that's a multicart).
