Aww.. That sucks. I left South Korea on September 3 to come back to Toronto. I went there for summer break for 2 months. oh well.
Anyways I will translate the important stuff for you cause I am Korean.
What: Darkrai.
Why: Its for celebrating the release of first movie from Animation Best Wishes series. I don't know what movie is but it involves Victini, Zekrom, and Reshram.
When: Guested already posted general dates and I am going to expand on that. But I am not writing down specifically where. Too much typing. All are september dates.
Only once department stores (Home Plus [Equivalent to Home Depot, I guess]) - 3rd, 4th, 10th, 11th, 17th, 18th, 24th, 25th.
Some places open on Fri, Sat, Sunday for every week within event period. those are listed above DS Lite and DSi.
How: You can receive through Infrared Communication in DS Lite and DSi for Black and White only. There is no 3DS in Korea yet.
I think that pretty much summarizes the advertisement.
