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