In the context of Nintendo Switch modding, "bin to nsp" typically refers to the process of converting raw partition images or firmware files (often in format) into installable Nintendo Submission Packages (

Understanding the Formats

• XCI (or "Bin"): Represents a "cartridge" image. These often come as multiple files or folders (sometimes labeled .bin or xcz).
• NSP: Represents an "eshop" title. This is the standard format for installing games directly to the Switch internal memory or SD card via homebrew installers like Tinwoo or GoldLeaf.

• Tinwoo Installer (a popular game installer) can install XCI files directly without converting them to NSP first.
• This saves time and PC storage space, as you don't need to unpack and repack the entire game.
