RetroArch gathers many emulators behind one front end. BizHawk also runs on separate system cores, but it is written in C# and built around rerecording and debugging. The Windows build is version 2.11, released on September 20, 2025, and the installer file comes from the official server at github.com.
TASEmulators and a mixed licence history
BizHawk comes from the developer TASEmulators, and its package ID is TASEmulators.BizHawk. It is free. The licence is mostly MIT, but the project describes part of it as an illegal combination of several incompatible GPL licenses, and points readers to its License URL for detail.
Cores for NES, N64, Game Boy Advance and more
Each system runs on its own core. The tags name NESHawk for the Nintendo Entertainment System, bsnes for Super Famicom, ares64 for Nintendo 64, mGBA for Game Boy Advance, and melonDS for Nintendo DS. Other tags point to Game Boy Color, Virtual Boy and WonderSwan Color support.
For casual players, the app offers full screen and joypad support. Beyond that, it includes full rerecording and debugging tools across all system cores, which is the part aimed at tool-assisted play.
