Sonic Adventure made use of the Dreamcast’s modem to download extra content – here’s a look at what was available
events were held to mark special occasions, beginning with a Christmas celebration for the game’s 1998 launch which placed trees and music in station square. a new year’s day 1999 event followed, and the first worldwide events celebrated the international dreamcast launches. twinkle park received a halloween makeover in 1999, and the final event celebrated new year’s day 2000.
these themed events allowed skilled players to win prizes. Japanese players could play item-finding contests in station square and mystic ruins, sponsored by sega and Famitsu. american players received three cobranded at&t/official Dreamcast Magazine time attack events in speed highway, red mountain and sand hill. european players could hunt reebok trainers in emerald Coast.
in celebration of the release of Samba De Amigo for dreamcast, this extra course for twinkle Circuit was made available for download. interestingly, this is one of six twinkle Circuit courses that are on the disc, but normally unavailable in the game – the other five are completely unused. this was the final dlc made available for the game, released on 27 april 2000.
after collecting a certain number of emblems in the game, users could download shiny Chao in rare colours. it was also possible to download menu themes that replaced the default announcer with character voices, but most of these files were only released in Japan.
