The phrase refers to the use of emulator software on Apple’s iOS operating system to play the Nintendo DS game, Pokmon Diamond. An emulator replicates the hardware and software environment of the original Nintendo DS, allowing the game’s ROM file (a digital copy of the game cartridge) to be run on an iPhone or iPad. Functionality mirrors the original handheld, simulating button inputs and screen display.
The appeal stems from the desire to experience Pokmon Diamond on a more modern and convenient device, circumventing the need for the original console. Furthermore, emulation allows for potential enhancements not available on the Nintendo DS, such as improved resolution or cheat code implementation. The practice also offers a way to revisit a classic game without acquiring or maintaining vintage hardware. However, it’s crucial to acknowledge the potential copyright implications associated with downloading and using ROM files, particularly if one does not own the original game.
