|ARZ Barrier||Unused door barriers from Aquatic Ruin Zone.|
|Unused Balkiry Frame||Unused frame of the Balkiry badnik with landing gear.|
|Walking Turtle||Walking sprites of the turtles that pop out of the badniks in Sky Chase Zone. Normally you'll never see this, since the animal never has the opportunity to hit the ground.|
|HPZ Icon||Level Select icon for Hidden Palace Zone, which never made it into the final game. The art however, is present in Sonic 3's level select.|
|WFZ Laser||Large laser shooting through a spinning platform in Wing Fortress Zone. Never seen in-game.|
|MCZ Ring Platform||Weird platform made of rings, placeable using debug mode. It moves back and forth depending on which side you stand on.|
|WFZ Spinning Pole||Weird spinning pole that acts like a badnik - you can destroy it, and it can hurt you, but it doesn't actually move.|
|Static or blank TV Monitor||Powerup monitor which harms you when broken. Never seen in-game.|
Unused Score Tally
The score tally is unused but was meant for levels with a single act (Sky Chase Zone, etc). It can be made to appear by using debug mode and placing, then breaking a capsule.
Unused Music Track
In the sound test, song $10 is actually a unused song. This has been established to be the music meant for Hidden Palace Zone.
Sonic 1 Sound Effects
There are a few sound effects leftover from Sonic 1 and can be heard in the sound test.
- 29 - Touching the R, Up, and Down Special Stage blocks.
- 31 - Scrap Brain Zone electricity.
- 3A - Touching color changing diamonds in the Special Stage.
- 43 - Special Stage giant ring entry noise.
- 49 - End of act bonus point icon.
True Level Order
The level order that is used during gameplay is actually quite different from the intended order according to the level slots. A simple level select Pro Action Replay code (FFFE10:??00) can be used to verify this:
|Order in gameplay||Actual|
|Emerald Hill Zone||Emerald Hill Zone (00)|
|Chemical Plant Zone||Metropolis Zone (04/05)|
|Aquatic Ruin Zone||Wing Fortress Zone (06)|
|Casino Night Zone||Hill Top Zone (07)|
|Hill Top Zone||Oil Ocean Zone (0A)|
|Mystic Cave Zone||Mystic Cave Zone (0B)|
|Oil Ocean Zone||Casino Night Zone (0C)|
|Metropolis Zone||Chemical Plant Zone (0D)|
|Sky Chase Zone||Death Egg Zone (0E)|
|Wing Fortress Zone||Aquatic Ruin Zone (0F)|
|Death Egg Zone||Sky Chase Zone (10)|
Level slots 01,02,03,05,09 all lead to Emerald Hill Zone and 08 is actually Hidden Palace. In the Simon Wai prototype some of these were used for scrapped levels. 02 was used for Wood Zone and 0E was used for Genocide City Zone.
Commentary found in the Sonic Jam strategy guide reveals that the level order could have been even more different. It states that Chemical Plant Zone was meant to be the 10th zone back when the game was planned as an 18 zone game.
There are some levels that have rings in places that can't be reached normally. This makes getting a Perfect bonus in these stages impossible.
