The Nsp File Is Missing A Program-type Nca «UHD 2024»

This error indicates an NSP (Nintendo Submission Package) archive expected to contain at least one program-type NCA (Nintendo Content Archive) — the file that holds executable game code — but none was found. Without a program NCA, the package has no runnable title content.

Use hactool to list the NSP’s contents:

hactool --titleid=<titleid> --sectiondir=./extracted <file.nsp>

Or, simpler:

hactool -t nsp <file.nsp>

You will see a list of NCAs. Look at the Type column:

NCA 0: Type=Program   ID=...
NCA 1: Type=Control   ID=...
NCA 2: Type=Data      ID=...

If you see no Type=Program at all → you’re dealing with a DLC or Update NSP (no executable inside).

If you want, tell me which NSP file you have (filename) and I’ll give exact hactool commands and the steps to inspect it.

The NSP File is Missing a Program-Type NCA: Understanding and Resolving the Issue

The world of gaming on the Nintendo Switch has opened up a plethora of possibilities for gamers, with the ability to install and play games from the Nintendo eShop, as well as from cartridges. However, for those who venture into the realm of homebrew and custom software, the process can sometimes be fraught with errors and compatibility issues. One such error that has been encountered by users is the message: "The NSP file is missing a program-type NCA." This article aims to demystify this error, explaining what NSP files and NCA types are, why this issue occurs, and how to resolve it. Or, simpler: hactool -t nsp <file

If you do step 3 or 4 before step 1, you will see the "missing program-type NCA" error.

To fix the error, you must understand the container. An NSP (Nintendo Submission Package) is essentially a digital shipping crate. Inside that crate are multiple smaller files called NCAs (Nintendo Content Archives).

Every legitimate game or application (XCI is different—hold that thought) contains several types of NCAs. Think of them as organs in a body:

The error "missing a program-type NCA" means the installer looked inside your NSP file, found the Control NCA (so it knows the game’s name and icon), but failed to find the Program NCA (the actual game logic).

In human terms: You have the box art and the manual, but the game cartridge itself is missing. The installer doesn't know what to do, so it aborts.
