*beats Starry to the punch*

Gold and Silver were released in North America on October 15, 2000, and this Friday marks the 10th anniversary. So, just like in Japan we'll be able to download a Mew over WiFi. The event lasts from October 15-30.
Finally! This is the first Mew I'll have since several I had back in Gen 1 (all through Game Shark / Game Genie). I tried getting the one on Ranch, and I was close, but sadly our Wii started having power issues that required them to wipe the memory to fix it. Thank God all my event legends are still on my Diamond version.
