Software that simulates the hardware of a classic handheld gaming console on Apple’s mobile operating system allows users to experience games originally designed for that console on their iPhones or iPads. This class of application translates game code intended for the Game Boy or Game Boy Color into instructions that can be executed by the iOS device’s processor. An example use case involves downloading a ROM file (a digital copy of a game cartridge) and opening it within such a program to begin playing the title.
The availability of these programs enables continued access to a significant library of classic games long after the original hardware has been discontinued. This preserves gaming history and allows newer generations to appreciate titles that were influential in the development of the video game industry. Moreover, these applications often offer features not available on the original hardware, such as save states, customizable controls, and enhanced graphics.
