BizHawk is an open-source libretro frontend, as well as a multi-system emulator designed predominantly around the production of Tool Assisted Speedruns (TAS). It is written in C# and requires .NET Framework 4.0 (in 1.X releases) or .NET Framework 4.6.1 (in 2.X releases) to run. BizHawk focuses on core accuracy and power user tools while still being an easy-to-use emulator for casual gaming.
