In March, 1995, Nintendo released several special edition Game Boy models with coloured cases, advertising them in the “Play It Loud!” campaign. Play It Loud! units were manufactured in green, red, white, black, yellow, blue, and clear (transparent), or sometimes called X-Ray in the UK. Most common are the yellow, red, clear and black. Green is fairly scarce but blue and white are the rarest. Blue was a Europe and Japan-only release, white was a Japanese majority release with UK Toys R Us stores also getting it as an exclusive edition to them. The white remains the rarest of all the Play it Loud colours. A rare, limited edition Manchester United Game Boy is red, with the logos of the team emblazoned on it. It was released simultaneously with the Play it Loud! handhelds in the United Kingdom. The Play It Loud’s screens also have a darker border than the normal Game Boy.
