BizHawk vs OpenEmu

BizHawk is an emulation project centered on EmuHawk, a multi-system emulator written in C#. It targets tool-assisted speedrunners with recording, playback, and debugging tools. EmuHawk records rerecordable movies for 45 or more systems, while the integrated TAStudio provides a piano-roll workspace for composing movies with savestates that rewind and adjust inputs. Other functions include save slots, named savestates, speed control, frame stepping, rewinding, screenshots, audio and video recording, and memory viewing, searching, and editing. Lua and C#.NET can control the frontend and emulator cores programmatically, and keyboard, mouse, and gamepad hotkeys can be rebound. Supported systems include Atari, Nintendo, Sega, Sony PlayStation, arcade machines, and DOS/Windows. BizHawk is free and open source, with the team’s original work under the MIT License. Installation instructions cover Windows and Unix, but current EmuHawk does not work on macOS; Android and iOS are unavailable.

OpenEmu is free, open-source video game emulation software for macOS. It organizes game backups into a unified library, adds box art and supports collections spanning consoles. Users drag and drop backups for scanning and organization. Modular cores from open-source projects emulate systems including Atari, Game Boy, Nintendo, Sega, Sony PlayStation and Super Nintendo; the project lists 31 supported systems. Generic HID-compliant USB or Bluetooth controllers can work immediately, with automatic mapping for recognized devices. OpenEmu is intended for games users already own, and BIOS files are required. The wiki describes an experimental arcade core plugin that is strictly unsupported. The latest release page identifies OpenEmu 2.4.1 binaries as Intel-only. The official site offers a macOS (OS X) application, but the version requirement was not rendered. The project lists save states, CD audio and cheat support, while online netplay is not available.
