MSX

The MSX standard was developed in the 1980s by ASCII with a little hand from Microsoft, and although it was pretty much unknown in the USA, it had a huge following in Japan, Russia, Europe, Brazil, and the Middle-East. Not only it was a fine all-purpose home computer, 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!
