Watara Supervision: Info Sheet and Video Featurette

The Watara Supervision is a stinker of a system that was only innovative in that it was the first hinged handheld system. Released in 1992, it attempted to compete with the Game Boy, which was first released in 1989, by offering a very low price system. This was crazy even at the time. Nintendo was way too entrenched and nobody would make games for this unknown system. On paper it had slightly better specs. The games however were generally terrible
