Sonic Uno was first started under a contest between Super and Robjoe to see whom could create the better hack all on their own. Super, excited with the project, quickly got underway redesigning Marble Zone while Robjoe put it off. On day 2 of the contest, Robjoe immediately forfeited, claiming art could not be more foreign to him. Super, already the victor, liked the direction he had taken and decided to put off his floundering S3K hack, Final Hope.
