MD.emu review
A feature-rich Sega emulator with saves, cheats, CD images, archives, and controller support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MD.emu is a paid, open-source emulator focused on Sega Genesis/Mega Drive, Sega CD, and Master System/Mark III software. It is aimed at Android users who want one application for several Sega systems, with support for supplied game files rather than bundled ROMs. The feature set also suits players who need save states, cheat codes, configurable touch controls, or external controllers. Official EmuEX support extends to iOS and Linux, while the current store listing is for Android.
Its strongest point is the breadth of Sega-focused features. MD.emu can load supported game files from ZIP, RAR, and 7Z archives, as well as Sega CD images through .cue or .bin files. Save states and backup-memory saves cover different progress needs, while Game Genie and Action Replay codes can be used through .pat files. Six-button controllers, four-player multitap support, Menacer and Justifier light guns, Bluetooth controllers, USB HID devices, and keyboards give it more control options than a basic touch-focused emulator. Video effects include Scale2x and hq2x shaders.
The main qualification is scope and maturity. Sega CD emulation is marked beta, so buyers specifically seeking that system should account for that status. The application also requires users to provide their own game files, and it does not include ROMs. MD.emu is a strong fit for Android users who want deep Sega-family coverage and extensive input, save, cheat, archive, and display options. It is less suitable for buyers seeking a free plan, netplay, or a broader platform footprint in one directly listed application.
