Soul Calibur was online in Japan, and in translating the website two pieces of long lost DLC have been recovered!
This will be added to the usual Dreampipe.net site group, but for the time being it's available on my seganet account. The two downloads are VMU minigames. The Inferno character DLC is still missing.
