BizHawk vs RetroDECK

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.

RetroDECK is a free retro gaming platform for Linux handhelds, desktops, HTPCs and PC consoles. It packages emulators, engines, ports, clients, utilities and the ES-DE frontend in a preconfigured Flatpak environment. The RetroDECK Configurator handles file compression and management, BIOS validation, preset management and component tuning. Steam ROM Manager and ES-DE favorites integration let users add games to a Steam library, while Steam Input layouts support devices such as Steam Deck and external controllers. RetroDECK can connect to RetroAchievements, and PortMaster provides a continuously updated catalog of downloadable ports. Sandboxing isolates the package components. The software supports x86_64 Linux systems, including Steam Deck and Linux desktops. Games, proprietary BIOS files and firmware are not included, so users must provide legally obtained files where required. Save states and cheat support are available. RetroDECK is volunteer-run software; donations are optional and do not provide perks or early access. The plan costs nothing.
