I would say it's yellow rather than gold. The box is the same colour as the Wii banner.
PS: These olympic games should have been held in Madrid.
Yeah, I noticed that as well. Banana yellow would've made a good colour for DKCR. I used the term gold because that what ONM referred to it as and I'm guessing they got the term from an official Nintendo and/or SEGA press statement. To avoid confusion I'll change it.
PS. Spain held the Olympics back in 1992, 20 years is quite a short space of time between two summer olympic games in one country. U.K and France (the two main finalists, last held Olympics back in 1948 and 1924 respectively if my memory serves me correctly. And even in 1948, the Government was planning to give the 1948 London Olympics to the US due to rationing and funding problems, but that's another story.
