Sonic 1 MD Prototype - Unreferenced Demo Data  @MDTravisYT
Uploaded June 2025 | Updated September 2026, 2 weeks ago
At offset 0x311C, there lies stray demo data. It is placed right below the demo data pointers. This data's also present in the final game, Sonic 2 and the 1103 prototype of Sonic 3.
This demo involves Sonic slowly walking forward, jumping once, then running at full speed for a few seconds.
Peculiar, isn't it?
Notes:
- The layout in this video has been modified so the inputs are easily visible.
- The freakout at the end is reading past the demo data. The actual end is just the long stretch of running.
Have fun with this! I'm not looking into this further. I have better things to do.
