Sonic the Hedgehog 2 (Sega Master System, Game Gear)
|Sonic the Hedgehog 2|
Developer: Aspect Co., Ltd.
Sonic the Hedgehog 2: featuring Tails as Princess Peach!
|"Crying Tails" Animation||Tails crying. Probably meant to be used in the ending cutscene when he is rescued.|
|"Bored Sonic" Animation||Three frames from Sonic 1 for the Master System. While the 8-bit versions of Sonic 2 used the spritesheet of the 8-bit Sonic 1, the waiting animation was changed. Hence, these are unused.|
|Early Death Sprite||An early version of the death sprite. Sonic's shoes have no stripe and are outlined.|
|Underground Zone Boss body||The entire body of the boss. Normally, only its head is visible.|
|Sky High Zone Boss body||The entire body of the boss. Normally, only its head and neck can be seen.|
|Sonic Monitor||While you can find this in a wall in Crystal Egg Zone, the graphics are obscured. When collected, it grants a continue.|
|Question Mark Monitor||May have given a random amount of rings or items, like in the 2-player mode of the Genesis version.|
|Grey Sneaker Monitor||May have slowed you down, like the Slow sneaker in the 2-player mode of Sonic 3.|
|Arrow Monitor||Most likely intended to be a checkpoint marker, like the 8-bit versions of Sonic 1.|
Gimmick Mountain Title Card
Originally, the level card for Gimmick Mountain Zone used its full name. Due to lack of space on the screen, however, "Mountain" was shortened to "Mt."
A build date string can be found in the ROM at 0x000C0:

A peaceful, ethereal-sounding tune. What this song could have been used for is unknown.
