Recently, Dreamcast Info Preservation Games just recently dropped the April 28th, 2000 E3 Prototype build. This would have showcased during the event, allowing you to try out various aspects of the game, and change to whatever character you'd like. It even has character specific dialogue introducing the demo, which probably hasn't been seen since those demos in 2000.
Check out the original release by the group here:
