Game emulation is the process of using software, known as an emulator, to replicate the hardware of a gaming console or computer. This allows users to play games designed for those systems on different devices, such as PCs or smartphones. Emulators mimic the original system's functions, enabling the execution of game code as if it were running on the original hardware. Emulation can also involve creating virtual environments for older games that may no longer be available on modern platforms. This practice helps preserve gaming history and allows new players to experience classic titles that shaped the industry.
