MSX

The MSX home computer was a rather successful and well received home computer. But what it's really good for is games. Metal Gear, Bomberman, Puyo Puyo - they all started here! Plus the carts have a Neo Geo effect and sense your region, some even unlock secrets in other games when placed in the second cartridge slot! Never released in America but still has English games. (Konami never had their own system but this might as well have been it)
