GameSpot News has unlocked secret characters and features in Capcom vs. SNK: Millennium Fight 2000 on the Sega Dreamcast. There are five secret characters: Akuma, Evil Ryu, Morrigan from Capcom, and Orochi Iori and Nakoruru from SNK.
Other features we found were music tracks from classic titles such as Street Fighter and Fatal Fury. There is also a pair-match mode where players can compete two-on-two against the CPU or a human opponent, as well as a ratio edit feature. You can unlock all of these by earning versus points when playing the game on the Dreamcast, in the arcades, and when playing SNK vs. Capcom for the Neo Geo Pocket.
