The Game Boy is an 8-bit fourth generation handheld game console developed and manufactured by Nintendo. It was first released in Japan on April 21, 1989, in North America later the same year, and in Europe in late 1990. It was designed by the same team that developed the Game & Watch series of handheld electronic games and several Nintendo Entertainment System (NES) games: Satoru Okada, Gunpei Yokoi, and Nintendo Research & Development 1.
The Sony Tablet S was released in 2011 around the same time the Xperia Play 2 was cancelled, much like the Xperia Play 2 the Sony Tablet S was also PlayStation Certified meaning you could download PlayStation Portable games.
Sadly an update to the PlayStation Store made the tablet unable to download & purchase PS One Classics.
