This refers to software that simulates the environment of Nintendo DS (NDS) handheld consoles on Apple’s iOS operating system. It allows users to play NDS games on devices like iPhones and iPads. For example, an individual might download an application that mimics the DS hardware and software, enabling them to load and play ROM files of NDS games.
The capability to replicate the NDS gaming experience on iOS devices provides a convenient alternative for those who wish to enjoy retro games without needing the original hardware. This emulation bypasses the need to carry a separate gaming console and allows users to take advantage of the portability and screen capabilities of their iOS devices. Historically, such applications have presented challenges related to app store policies and legality of ROM distribution.
