version called PlayOnMac. Lutris is an open-source application to easily install Windows games on Linux. Bordeaux is a proprietary Wine GUI configuration manager that runs winelib applications. It also supports installation of third-party utilities, installation of applications and games, and the ability to use custom configurations. Bordeaux currently runs on Linux, FreeBSD, PC-BSD, Solaris, OpenSolaris, OpenIndiana, and macOS computers. Bottles is an open-source graphical Wine prefix and runners manager for Wine based on GTK4+Libadwaita. It provides a repository-based dependency installation system and bottle versioning to restore a previous state. WineGUI is a free and open-source graphical interface to manage Wine. It allows you to easily create Wine bottles and install Windows applications or games. Functionality The developers of the Direct3D portions of Wine have continued to implement new features such as pixel shaders to increase game support. Wine can also use native DLLs directly, thus increasing functionality, but then a license for Windows is needed unless the DLLs were distributed with the application itself. Wine also includes its own open-source implementations of several Windows programs, such as Notepad, WordPad, Control Panel, Internet Explorer, and Windows Explorer. The Wine Application Database (AppDB) is a community-maintained on-line database about which Windows programs works with Wine and how well they work. Backward compatibility Wine ensures good backward compatibility with legacy Windows applications, including those written for Windows 3.1x. Wine can mimic different Windows versions required for some programs, going as far back as Windows version 2.0. However, Windows 1.x and Windows 2.x support was removed from Wine development version 1.3.12. If DOSBox is installed on the system (see below on MS-DOS), Wine development version 1.3.12 and later nevertheless show the "Windows 2.0" option for the Windows version to mimic, but Wine still will not run most Windows 2.0 programs because MS-DOS and Windows functions are not currently integrated. Backward compatibility in Wine is generally superior to that of Windows, as newer versions of Windows can force users to upgrade legacy Windows applications, and may break abandoned software forever as there is nobody adjusting the program for the changes in the operating system. In many cases, Wine can offer better legacy support than newer versions of Windows with "Compatibility Mode". Wine can run 16-bit Windows programs (Win16) on a 64-bit operating system, which uses an x86-64 (64-bit) CPU, a functionality not found in 64-bit versions of Microsoft Windows. WineVDM allows 16-bit Windows applications to
