Tools like NSTool or custom extraction scripts unpack .nsp or .xci (cartridge image) files into individual raw binary fragments ( .bin or .nca ) to modify game textures, apply translations, or build mods. Once edits are made, developers need to pack those raw fragments back into a clean, installable .nsp format. Creating Forwarders for Homebrew Applications

Among the most common tasks for advanced power users is managing backups that consist of raw binary dumps ( BIN files ) or cartridge images accompanied by unique cryptographic keys, and packaging them into a cleanly installable digital format: the Nintendo Submission Package (NSP) . For a modded Switch (running Atmosphere, SX OS,
When working with these file architectures, a few staple desktop applications handle the heavy lifting. Almost all file manipulation utilities require your console's unique encryption keys ( prod.keys ) to decrypt or parse game data. NSCB (Nintendo Switch Content Builder)
