Originally released as the Nintendo Gameboy Color in late 1998, it wasn't the first colour-screened portable gaming console, but the Gameboy Colour certainly revolutionised pocket gaming for Nintendo fans. In response to pressure from game developers for a more sophisticated handheld platform, the Gameboy Colour brought with it many major improvements over the original Gameboy, including a twice-as-fast processor, four times the RAM and an infra-red communication port that allowed two Gameboy Colours to interact with each other from up to 2 metres away. The infra-red feature was particularly popular for multi-player games such as Pokemon Red and Blue, which allowed players to battle each other and trade Pokemon without a link cable. But most importantly, gamers were now able to stare at a full colour screen that had access to over 32,000 colours. Although discontinued in 2003, the Gameboy Colour remains popular amongst collectors and those wanting to relive some of their youth - and you can find it right here on eBay.
Refurbished, pre-owned and limited editions
If you're one for the classics, you might enjoy the Gameboy Colour in its original purple colour, of which there are plenty on eBay. However, Nintendo also released many limited edition colour casings, including an "Aussie version", a yellow Pikachu Pokemon edition, plus a range of bright pastel and see through casings. Some sellers list refurbished items, which often means they have taken a pre-owned Gameboy Colour and cleaned it up to ensure it is in perfect working order, with some refurbishers even offering short warranties on their products. The Gameboy Colour isn't much good without games to play - if you're lucky, you might find a seller bundling games with the console in their listing. Otherwise, you can find plenty of Gameboy games on eBay.
Other Gameboy models
The Gameboy had one last iteration before it was replaced with the Nintendo DS line of pocket gaming consoles, in the form of the Gameboy Advance, which was backwards compatible with many Gameboy and Gameboy colour games, but added shoulder buttons, a significantly better screen and faster technology.
