A late prototype of Sonic the Hedgehog CD for the Sega CD.
Notes
- Level select can be activated at the title screen by pressing B
- Minor code changes in all files.
- Wacky Workbench Act 2 (Past and Good Future) and Stardust Speedway Act 2 (Present and Good Future) contain the most differences in this build (R62B, R62C, R72A, R72C).
Quartz Quadrant Zone Act 3 (R53C__.MMD, R53D__.MMD)
The boss in both good and bad future has a different color
Good Future
Bad future
The background in Bad Future starts higher than in the final.
Visual mode (VM____.MMD)
In builds 712 and 801, there are 5 patterns that are loaded into the same place in Video RAM in succession (overwriting each other). The last pattern (#5) is changed between 712 and 801, fixing the OPENNING typo. Patterns #1-#4, which presumably show the development progression of the Visual Mode are removed in the final, leaving only pattern #5.
