Tails is captured at a different time of day in the introduction sequence. On the Game Gear, Eggman swoops down and captures Tails, while on the Master System he has already been caught.

Title cards have been squashed to fit the Game Gear's resolution.

The level select screen has been optimised for both platforms. The colour scheme is also different.

Under Ground Zone

Master System version
Game Gear version

In the Game Gear version, all of the bosses are made harder by the smaller screen resolution. Pit Master is the most famous example - with less of the playfield visible, it is much harder to avoid the silver balls as they bounce down the slope, and to make matters worse, some of these balls also go higher. This is exacerbated when using a real Game Gear, as the screen doesn't lend itself well to fast moving objects.

On the Game Gear, the heads-up display is removed when fighting a boss.

In UGZ1, the room on the bottom left hand side has been made smaller so you can still see the left hand wall despite the Game Gear locking the camera further to the right than the Master System.

In UGZ2, this spring has been removed in the Game Gear version, possibly to make that section a little less frustrating for a new player.

In UGZ2, the Emerald has been shifted to the right so it is still in the centre of the screen if you scroll the camera as far right as it can go.

Master System version 2.2

There are several bad bugs related to this falling bridge in SMS v1 which were apparently fixed in the Game Gear version by making the wall completely solid.[1] Master System v2.2 completely removes this bridge.

Aqua Lake Zone

Green Hills Zone

Master System version
Game Gear version

The boss area for Dohyo Master was adjusted for the Game Gear's resolution, with its movements matched to suit. Like all the bosses, however, the lack of physical space to move and screen visibility makes it a more difficult opponent on the Game Gear. The boss itself can also attack twice in a row sometimes before revealing its "weak" state, adding to the difficulty.
