BizHawk vs Snes9x

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.

Snes9x is freeware for playing most games made for the Super Nintendo and Super Famicom systems. Desktop builds are listed for Windows, Linux, and macOS, with additional libretro core builds for Android, Emscripten, Wii, Switch, GameCube, and PSP. Running games requires SNES ROM images. Snes9x can save game state to freeze files and game data to SRAM files. Windows documentation describes Game Genie and Pro-Action Replay cheat formats, a cheat search feature, and recording gameplay actions for later playback. Netplay is documented for as many as five players, but the project notes that it has not been maintained or tested in a long time and might be broken. The Unix documentation says the emulator does not reproduce exact sub-cycle timing between major system components, so games with strict timing needs may not run. The project lists the software as free, with a plan price of free. Its listed platforms include Android, Linux, macOS, and Windows.
