Game Gear:Game Gear Model Differences

Game Gear Versions
The Game Gear was released by Sega in a few different configurations and later re-released by Majesco. The different Sega revisions have no difference whatsoever in output quality, however the Majesco version is a slight improvement.

Sega vs Majesco
With permission from Sega, the company Majesco re-issued the Game Gear in the year 2000. This version of the Game Gear isn't compatible with the TV Tuner or Master Gear Converter (although it's compatible with another SMS-to-GG converter called the Nuby Converter.) This version has a slightly improved screen and is less prone to failures (most likely as a result of using better capacitors). Both screens are extremely poor quality compared to modern LCD's however the screens used in the Majesco versions are definitely a bit better, with more accurate color representation.

It's very easy to tell which Game Gear's are the Majesco model, as the logo above "Game Gear" is all white, instead of red, greed and blue. Other notable changes are the stickers in back and the darker color of the plastic.

Curved screen cover versus flat screen cover
Some Game Gear systems came with a front screen cover that was flat instead of rounded. This design does not effect the way the screens look and is purely an aesthetic difference. Game Gear systems with the flat screen cover don't have TMSS, which is the annoying "produced by" screen that appears for a few seconds before launching the game. As soon as you power on these models, it immediately loads the game. This screen is only displayed for a few seconds.
