In this video, I showcase two tech demos of Sonic Adventure DS — a fan game by Yacker, built from the ground up for Nintendo DS and PC. The first demo, presented at SAGE 2022, features a port of Speed Highway with basic objects like springs and spinners, but lacks audio. The second demo, showcased at SAGE 2023, offers significant improvements: added audio, a more detailed stage, new objects, and the ability to run on real DS hardware. Both versions showcase the project's potential but remain in tech demo status.
