Back around March, 2005 Sony released a special version of Minna no Golf Portable (Hot Shots Golf) with Coke branding. They also produced a special PSP to go along with it. They made 1300 of these and gave them away in a special promotion in Japan. (When I bought this, the seller only had the system, not the Golf game... If you have a spare Coca-Cola Minna no Golf Portable, I'm interested!)

Here's the box this was all shipped in:
