A misleading name for an old FamiCom or Super Famicom clone (of the "9999 games in 1" class), wrapped in a case which looks like a Sony Playstation (PSX). In this age of hype for 64 / 128 bit Computer And Video Games Consoless, it's easy for some parents to buy a cheaper box with a misleading name like that.
Maybe you've seen one of those in some second-handed electronic store near you, but you didn't notice the fake.
