Emulation software is a type of program that allows one computer system to mimic the functions of another. This enables users to run software or games designed for different hardware platforms, such as older video game consoles or operating systems, on modern devices. By replicating the original system's environment, emulators provide a way to access legacy applications and experiences. Common examples of emulation software include Dolphin for Nintendo GameCube and Wii games, and BlueStacks for running Android apps on Windows or Mac computers. Emulators can be useful for developers, gamers, and anyone interested in exploring software from different eras or platforms.
