- Back to: Sonic the Hedgehog CD (prototype 510)/Comparisons.
Stardust Speedway makes no secret about being unfinished in the 510 prototype. It is missing rings and objects, and for a level so reliant on automation, this makes it impossible to negotiate without debug mode.
Zone 1
A different lighting technique is used in the present version of the zone. A scrolling beam of light moves up and down the screen, turning the world into a hideous mess. In the final, smaller vertical and diagonal light beams flicker, and appear in the bad future version too.
The good future sports a different colour scheme.
The past also has problems, with yellow highlights in the final being blue in this prototype.
The bad future meanwhile has constant lightning strikes, meaning the background flashes on a loop.
The flashing creates artifacts in the sky as not all tiles are using their correct palettes.
Eggman's statue/building which you pass by in act 2 is visible in the far distance of act 1. This detail is removed from the final version for some reason.

Zone 3
Neither Eggman nor Metal Sonic turn up in act 3. Instead, you get a hole in the floor, because pits in Sonic prototypes are much more threatening.
Amy is also missing, meaning it's impossible to finish the level by normal means.
The developers seem to have planned for this, however, as a capsule exists on the platform above.

The flowers in the 510 prototype are unique to each zone. In Stardust Speedway, however, most of the flowers are mapped to rotating palettes intended for parts of the background.
