BizHawk
What it is
BizHawk is a free multi-system emulator for Windows and Linux, with EmuHawk combining playback, recording, and debugging tools aimed at Tool-Assisted Speedrunners. Listed system support spans 3DO, Apple II, arcade machines, Atari, Commodore, Nintendo, Sega, and PlayStation consoles. EmuHawk provides 10 save slots with hotkeys as well as unlimited named savestates. Playback features include speed control, frame stepping, and rewind. Users can record input as TAS movies and capture screenshots, audio, and video to files. Debugging tools can view, search, and edit memory across emulated hardware components. Lua or C#.NET can control the core and frontend programmatically. Keyboard, mouse, and gamepad hotkeys can be rebound, and an input mapper works with emulated gamepads and peripherals. The Linux release omits the Mupen64Plus core for N64 and targets x86_64 CPUs. Current BizHawk is unavailable on Android and iOS, while macOS support is limited to older releases or technical workarounds. The project recommends stable releases when stability matters.
For and against
For
- Free emulator with Windows and Linux releases.
- Includes 10 hotkey-accessible save slots.
- Unlimited named savestates are available.

The verdict
BizHawk combines multi-system emulation with save-state, recording, scripting, and debugging tools. Check the platform and core limitations, particularly if you need N64 emulation on Linux or current macOS support.
Who it suits
It suits Tool-Assisted Speedrunners and users who want recording, playback, and debugging tools alongside multi-system emulation. It is intended for Windows or Linux users rather than current Android or iOS users.
