Sonic Classic Heroes is an extensive ROM hack of Sonic the Hedgehog 2 that combines the original game and Sonic the Hedgehog and adds a lot of new features. The main showcase is the ability to choose up to three characters to play the game with and the ability to switch between characters during gameplay. A number of features from Sonic 3 & Knuckles have also been added such as each character having their own unique ability, elemental shields, and the ability to save your progress. Certain bugs that were in the original Sonic 2 have been fixed and certain gameplay mechanics have been improved for a smoother playthrough.

For this run, CyanTheGamerhog01 decides to go for 100% completion by collecting all the Chaos Emeralds present in both the first and second games with the main trio of Sonic, Tails, and Knuckles, doing so in record time.
