The Nsp File Is Missing A Programtype Nca Fix File

The error message "The NSP file is missing a Program-type NCA" (Error 0007-0034) typically occurs when an emulator or console tries to launch a file that is not the base game, or if the file itself is incomplete. Common Fixes

Select the Base Game File: This error often happens if you accidentally try to launch an Update or DLC file directly.

Ensure your shortcut or emulator is pointing to the Base NSP file, which is usually significantly larger than updates.

Move updates and DLC files to a separate folder so tools like Steam ROM Manager don't mistake them for the main executable.

Update or Reinstall Signature Patches (Sigpatches): On modded hardware, outdated or missing sigpatches are a frequent cause of NCA-related errors. the nsp file is missing a programtype nca fix

Download the latest sigpatches for your current Atmosphere and firmware version from a trusted source.

Some users find success adding KIP1PATCHES=nosigchk to their hekate_ipl.ini file under the bootloader folder to bypass verification errors.

Verify File Integrity: The error can indicate that the file was corrupted during transfer or extraction. Try re-copying the file from your source.

If using split RAR archives, ensure all parts were extracted correctly without "data errors". The error message " The NSP file is

Use the Emulator's NAND Installation: Instead of running updates directly, use the emulator's internal install function (e.g., File > Install to NAND in Yuzu/Ryujinx) to properly link updates and DLC to your base game.

Convert to XCI: If an NSP continues to fail, some users have bypassed the error by converting the file to XCI format using tools like SAK (Switch-A-Knef).

Are you seeing this error on a Steam Deck or a modded console? The NSP file is missing a Program-type NCA. : r/EmuDeck

Example with NSCB (command line):

nscb info yourfile.nsp

Look for output like:

NCA IDs:
  - 0100123456789000.nca → ProgramType: Program (0)  ✅
  - 0100123456789001.nca → ProgramType: Patch (1)    ⚠️
  - 0100123456789002.nca → ProgramType: AddOn (2)    ❌ (only DLC)

If you see only Patch or AddOn and no Program → the error will occur.

What Causes This?

Incomplete or Corrupt Dump: The game was dumped incorrectly, omitting the main program NCA.
Split or Base-Only Release: Some NSP files contain only update/DLC NCAs or are split across multiple files.
Improper Conversion: Converting from XCI to NSP or using faulty repacking tools can strip the program NCA.
Manual File Tampering: Deleting what appeared to be a “duplicate” NCA may accidentally remove the critical program component.

Step 4 – Repairing a Merged NSP (Advanced Fix)

If you previously merged a base game with an update and broke the Program NCA, use SAK (Switch Army Knife) or NSC_Builder to split them again.

Using SAK (PC):

Open SAK → "Tools" → "Split NSP".
Load your broken merged NSP.
It will separate into base.nsp and update.nsp.
Test base.nsp first – if it loads without the Program error, you fixed it.
Then re-merge properly: SAK → "Merge NSP" → add base first, then update → use "Standard merge".
