The phrase refers to acquiring a digital copy of the Pokmon Crystal game, originally released for the Game Boy Color, that is specifically designed to be played on the Nintendo 3DS Virtual Console. This usually involves obtaining a ROM (Read-Only Memory) file from the internet. As an example, one might search for a file that allows them to play the classic Pokmon adventure on a modern handheld system, mimicking the original experience through emulation.
Accessing and utilizing this type of game file provides convenience, allowing individuals to experience a classic title on contemporary devices without needing the original hardware and physical game cartridge. Further, it allows portability, offering gaming on the go. Historically, the distribution of these game files has raised copyright and intellectual property concerns, as unauthorized distribution infringes upon the rights of the copyright holder, Nintendo.
