• MadChess 2.1+ does not require any runtime. It runs self-contained on Windows, Linux, or Mac. This is made possible by .NET 6 or the previous runtime known as .NET Core. I provide binaries only for Windows. However, you may compile MadChess for Linux.
• MadChess 2.0- requires the version of Microsoft .NET specified in the .NET Runtime column. If not present on your PC, you need to install the .NET Framework prior to running MadChess. These versions of MadChess run only on Windows.

To analyze positions or play a game, you need a Graphical User Interface (GUI).
