The World Ranking Features for Sonic Adventure have been restored after being offline for over 14 years!
You can use the world rankings feature by using DreamPi DNS 126.96.36.199. Create a ranking upload by highlighting a file on the file selections screen and hold Y+A until you hear the ‘ring’ sound. Then go to the ‘internet’ option in the main menu
Sending ranking data requires an account on Dreampipe BB for username and e-mail information on the ranking
