Dega vs MasterEmu

Dega is an emulator for Sega Master System, Mark III, and Game Gear games. It runs on Windows and *NIX systems; its README names Windows 95, NT, 98, 2000, ME, and XP. The software is free for non-commercial use only, and the GitHub repository has no releases. Dega supports Python scripting for input, resets, movie playback and recording, and access to a running game's RAM. Python can be used as a module in another program or embedded in the emulator. The distribution includes memory.py, a Python memory viewer and trainer. Users can record a movie and continue recording later from a saved state. Windows provides save-state slots, and Dega also supports a gzip-compressed .dgz save-state format. Other features include loading ROMs from ZIP files, AVI encoding from movie files on *NIX, and Yamaha 2413 FM audio for machines equipped with that chip. It can also combine some games' flickering-glasses effect into a red-and-blue image for red/blue glasses. Technical information estimates compatibility at 97%.

MasterEmu is a free, open-source Android emulator for Sega Master System and Sega Game Gear. It loads .sms and .gg ROM files from internal or external storage, including ZIP archives. The app supports Pro Action Replay and Game Genie cheat codes, physical controllers, and button remapping. Users can save and load emulation states, import or export states, and use automatic SRAM saving for supported ROMs. Display options include auto-rotation, locked orientation, widescreen, and optional 4:3 horizontal presentation. The listing states support for Android 4.4 through Android 13 and Android TV. MasterEmu has no ads or in-app purchases, and its source repository is on GitHub. Users must obtain ROMs legally; the maker does not provide sources. The maker identifies himself as a lone programmer and says he is not affiliated with Sega.
