MasterGear review
A mature Sega emulator with NetPlay, debugging, cheats, and broad 8-bit console support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MasterGear is an emulator for Sega Master System software and a broad group of related 8-bit systems, including Game Gear, SG1000, SC3000, SF7000, Mark II, and Mark III. It is aimed at players and preservation-focused users who provide their own legally obtained game files. Its feature set also suits users who want more than basic playback, with save and load states, cheat support, network multiplayer, and a built-in debugger.
Platform coverage is practical rather than universal: current downloads are listed for Windows, Linux, and Android. The Windows and Linux versions are free, while Android is offered as a paid app. MasterGear does not require a BIOS, and it supports configurable video scaling, scanlines, and fullscreen modes. Its sound features include FM sound emulation and MIDI soundtrack recording, while serial EEPROM emulation and multiple cartridge formats add support for different software requirements.
The main strength is breadth within Sega's early console and computer hardware, combined with NetPlay, Cheatopedia and GameGenie features, and save-state sharing on Android. That makes MasterGear a strong fit for users who value mature Master System support, debugging, and network play in one application. It is less suitable for users who require open-source software, a wider range of modern platforms, or bundled game content. Anyone choosing it should also plan to supply legally obtained ROM files, since the emulator does not include them.
