Also known as the AT&T/Official Dreamcast Magazine DLC.

These downloads were available for US players as part of a contest called the Sonic 2K Contest, where players could win various prizes.

SA1's official Time Attack contests usually just involved uploading a save file, but these ones were different - they changed up the game!

They're actually made with the same basic system as the Japanese scavenger hunt packs (QUO/Famitsu), just utilising the objectives in different ways to create new types of minigames.

8 October 2017: Thanks to modding advances, you can now play these in the PC version! All challenges are part of the same pack - just play as the appropriate character to activate them. Recreations by PkR.
