There are more than one commercial for Super Smash Bros Melee in Japan. Check them all out! Update: Links fixed!
It appears that Nintendo has made four commercials for Super Smash Bros Melee (or Super Smash Bros DX as it's called over there) in Japan. Well, it's really kind of just 2 commercials. But each one has a 15 and a 30 second version. Japanese Nintendo site N-Styles has put them all up. Since we can't link directly to their article, here are the links to the four commercials. They are in .zip format so you will need WinZip to open them.
UPDATE: All ads have been moved to hardcoregamer.com's media space (w/our thanks) & the links have been fixed up.
First Commercial (30 seconds) (This is the same commercial PGC previously posted)
