A late PAL build.

  • The introduction still lacks many sound effects.
  • The jingle for opening the sewer lids in Toxic Caves is shortened in this version.
  • Robotnik's ship during the destruction animation debris switches to the wrong palette partway through. This happens in the final as well, but is more noticeable here.
