v0.28A is an early prototype of Sonic CD, dated May 12, 1993. It was dumped by drx on October 26, 2019 as part of Sonic Month.

While compiled just two days after the widely-known 510 prototype, this build still contains noticeable differences in comparison. This is also the first time a proper dump has been made of a prototype from around the same time period.

Differences

  • The Special Stage data is the only game-related file unchanged from the 510 build.
  • The Past music doesn't exist at this point, with those areas instead just playing the Present music.
  • Special Stage rings no longer appear at the end of every Act.
  • The "Comin' Soon" screen appears after completing Tidal Tempest Act 3.
