Fix: This happens if the source .bin file is encrypted with a higher firmware key than what is present in your prod.keys file. Redump your console keys using the latest version of your custom firmware.

The first and most important step is identifying what kind of .bin file you have. Look at the file size and accompanying files.
Searching for a "bin to nsp top" review typically leads to discussions about converting raw game data ( files) into the Nintendo Submission Package (
This scenario is the most frequent. A BIN file could be a raw, unencrypted dump of a game cartridge. To convert this raw data into an installable NSP, the process requires multiple steps. A dumped BIN file often contains a complete partition layout and file system that must be properly extracted and rebuilt into the NSP structure. This is where specialized tools come into play, using methods similar to converting between other Switch formats.
Put your prod.keys file into the z_tools/ directory inside the NSC_Builder folder.
linkle is another command-line utility, written in the Rust programming language, designed for creating and converting files for the Nintendo Switch. Its main feature is the ability to pack a directory of files into an .nsp file. The files will be stored in the PFS0 format (a partition filesystem used for Switch packages).
The homebrew scene moves fast, and firmware updates can sometimes break older conversion tools. Always ensure you are using the latest version of your chosen software and that your prod.keys are updated to match your console's current firmware.
