BizHawk vs Dega

BizHawk is a free multi-system emulator for Windows and Linux, built around the EmuHawk interface. It is aimed at Tool-Assisted Speedrunners and combines playback with recording and debugging. The project lists systems including 3DO, Apple II, arcade machines, Atari, Commodore, Nintendo, Sega, and PlayStation consoles. EmuHawk provides 10 hotkey-operated save slots as well as unlimited named savestates, along with speed adjustment, frame stepping, and rewind. Users can record input as TAS movies and save screenshots, audio, and video. Debugging tools let users inspect, search, and edit memory across emulated hardware, while Lua or C#.NET can control the core and frontend programmatically. Keyboard, mouse, and gamepad hotkeys can be rebound, and an input mapper covers emulated gamepads and peripherals. The Linux build targets x86_64 and omits Mupen64Plus for N64. Current releases are unavailable on Android and iOS; macOS use is limited to older releases or technical workarounds.

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%.
