I’ve recently capped and put online four vintage SNK ads. These are capped directly from LaserDisc and should be very agreeable quality. First up a Samurai Shodown 30-sec ad, two 30-sec Fatal Fury 2 spots, and a five minute Fatal Fury 3 promo video:
These vids use XVID, and the best xvid codec I’ve found is FFDShow.

has direct-linked my videos, which I discourage is staffed with wonderful, happy + reasonable people. Yay for gamers worldwide. If you want to share these, and I would be happy if you did, please link to this page.
