It refers to software designed to replicate the functionality of a specific handheld gaming console from Nintendo on Apple’s mobile operating system. Functionally, this allows users to experience games originally developed for the dual-screen device on their iPhones or iPads.
The appeal lies in providing access to a library of classic games on readily available hardware, circumventing the need for the original console. The development and distribution of such software have often occurred outside of official channels, raising questions regarding copyright and intellectual property.
