Gameboy has not defeated the Playstation 2 in terms of sales. I think the chart combined Gameboy, with Gameboy Color sales. I don't know why, but I think that's what they did. Since the Gameboy, and Gameboy Color, are totally different portables, you cannot combine their sales, and say that they defeated the Playstation 2. Since neither of them, by themselves, sold more than the Playstation 2, the Playstation 2 is still the undefeated champion. And even if the Gameboy, or Gameboy Color, did beat the Playstation 2 in terms of sales, they are portables, not consoles, so the Playstation 2 would still be the undefeated champion of the consoles.
