Sonic the Hedgehog Spinball (Mega Drive prototype; 1993-08)
From Sonic Retro
Found by Elliotro, Sonic Spinball Beta is not much different from the final and only varies in some ways.
List of Changes between Beta and Final:
- Debug mode.
- Incomplete bonus stages.
- Some pallete changes.
- An invincible final boss.
- A different / glitchy intro.
- Animals that appear from badnicks are different.
