ares vs Dega

ares is a free, open-source emulator for multiple systems, with a stated focus on accuracy and preservation. It supports systems including Arcade, Atari 2600, WonderSwan, ColecoVision, NES, SNES, Nintendo 64, and PlayStation, though some listed systems are experimental. Playback options include save states, run-ahead, rewind, and fast-forward. Pixel shaders and optional color correction can alter display characteristics, while Virtual Game-Pads let users configure controls for use across emulated systems. The interface framework uses WinAPI on Windows, Cocoa on macOS, and GTK2 or GTK3 on POSIX platforms. Simple debugging features such as trace logging support development of original software for supported systems. Windows builds support Windows 7 or later; AMD64 binaries require at least Intel Nehalem or AMD Jaguar architecture. macOS binaries require Catalina 10.15 and support Intel and Apple Silicon. The project prefers Linux users compile from source and points to third-party packages rather than official Linux binaries. Source code uses the ISC license. Android is not supported, and a BIOS is required.

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%.
