The Nintendo 3DS is a popular handheld gaming device that was released in 2011. It features a glasses-free 3D screen, a wide range of games, and the ability to connect to the internet. One way that gamers can play 3DS games is by using a ROM (Read-Only Memory) file, which is a copy of the game’s data that can be played on a computer or other device.

The Nintendo 3DS ROM standard is the format in which 3DS games are distributed as ROM files. The format is designed to be compatible with the 3DS hardware and software, and it includes all of the necessary data and files for the game to run. The standard is widely used by gamers who want to play 3DS games on devices other than the 3DS itself, such as on a PC using an emulator.
