Sega Game Gear

🏭 Sega📅 1990

Sega's ambitious color handheld was essentially a portable Master System, sharing 85% hardware compatibility. Its 3.2" backlit screen was revolutionary in 1990, though notorious for 'screen rot' capacitor issues. The system's TV Tuner accessory (Japan-only) made it a portable television, while the Master Gear Converter enabled full library access. Though battery-hungry, aftermarket solutions like the PowerBack extended playtime. The system found unexpected success in Brazil through Tec Toy's localized versions. Rare variants include the clear blue 'Sports Gear' and the Majesco re-release with improved LCD. Modern collectors seek homebrew like the 2020 port of Duke Nukem 3D pushing its Z80 beyond intended limits.
