But with the advancement of technology and the dedication of developers, modern ROM emulators have become incredibly sophisticated, capable of delivering near-perfect emulation of many classic consoles. Some emulators even offer enhanced features, such as save states, cheat codes, and upscaling, which further enhance the gaming experience.
