When turning on the game hold + until 2 ring noises chime.
Pressing and at the same time on the D-Pad will result in incredible acceleration and speed to the left. This is mainly useful in emulation (and has been extensively used in the Tool-Assisted Speedrun), while it's unfeasible on a real unmodified console.

Some unused sprites of Tails crying. Probably meant to be used in the ending cutscene when he is rescued. | |
These three animations are from Sonic 1 for the Master System, but were found in Sonic 2 for the Game Gear. | |

The entire body of the Under Ground Zone boss can be seen here. Normally only its head is visible. | |
The entire body of the Sky High Zone boss was also drawn. Normally only its head and neck can be seen. | |
Sonic monitor. This one isn't really unused; you can find it hidden in a wall in Crystal Egg Zone, but the graphics are obscured. When collected, it grants a Continue. | |
Question mark monitor, possibly set to give the player a random amount of rings or items, like in the 2-player mode of Sonic 2 for Mega Drive. | |
Grey Sneaker monitor which might have slowed you down, similar to the Slow sneaker in Sonic 3's 2-player mode. | |
This could have been a checkpoint marker, like the 8-bit version of Sonic 1. | |
Under Ground Zone Bricks. | |
The remains of Green hill zone style tubes for Under Ground Zone. | |
Miscellaneous Under Ground Zone tiles. | |
Under Ground Zone floating platform. | |

Sky High Zone object - probably another platform. | |
Unused Aqua Lake Zone tile. |
Gimmick Mountain name
Originally the level card for Gimmick Mountain wasn't going to have a shortened name. Hivebrain discovered the word "Mountain" within the ROM. Due to lack of space on the screen Mountain was shortened to Mt.
