The phrase describes the acquisition of a specific iteration of the Super Mario video game series designed for play on the Nintendo DS handheld console. It explicitly refers to obtaining the game files, usually in a ROM format, through electronic means. The user typically seeks these files to play the game on an emulator, a piece of software that mimics the hardware of the original Nintendo DS system, or, less commonly, on a flash cartridge used with a physical Nintendo DS console.
The popularity of accessing these game files stems from several factors. Nostalgia for the classic Super Mario games is a key driver. Further, the convenience of playing on readily available devices such as computers or mobile phones using emulators contributes significantly. Historically, the release of Super Mario games on the Nintendo DS platform marked a period of innovation and expansion within the series, introducing new gameplay mechanics and visual styles that resonated with a broad audience.
