Sonic Adventure 7 is a hack of Sonic 3D Blast 5, made in 1999, although this hack is for the Game Boy Color. The game adds color, alters some of the graphics and changes the order of the levels, with the fourth level from S3DB5 becoming the first level. What used to be a remake of the intro from Sonic 3D Blast was replaced with Sonic & Knuckles' intro, and the title screen is very poor digitization of Sonic Adventure's box art. Strangely, the game includes a manual which is mostly a poorly done edit of Sonic Blast's manual, with most references to Knuckles being replaced with the Sonic Adventure 7 logo, despite Knuckles himself appearing in the intro (in green.)
