A late PAL prototype that, despite its date (5 days away from U.S. final), is believed be from earlier that month.
General Differences
- 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.
