The tool will read the TMD, parse the ticket for the title key, decrypt the common key cipher, and begin rewriting each .app file into a .dec or raw format.
As of 2025, the Wii U eShop is completely shut down. That means no new official downloads. However, preservation efforts continue. The developers behind CDecrypt 2.0 have hinted at a focusing on:
cdecrypt game.cia
Version 2.0 adds better CIA decryption, improved error handling, and support for newer key formats. cdecrypt 2.0
: You can execute the app from any system path without needing to drag the executable directly into your game files folder. How to Use CDecrypt 2.0 Method 1: The Quick Drag-and-Drop (Windows Only)
Emulators like Cemu cannot directly execute native, raw encrypted raw dumps or NUS structures. To understand why CDecrypt is required, look at the transition it performs:
is a C++ command-line utility originally developed by Crediar to decrypt Wii U NUS content, which includes games, updates, and DLC. While the original tool was a foundational piece of tech, modern forks—often referred to in the community as 2.0 or updated versions—have significantly improved its usability. The tool will read the TMD, parse the
In the early days of Wii U hacking (circa 2016-2018), the only way to decrypt these files was to use a console-specific key extracted from your own Wii U’s NAND (a process known as OTP dumping). The original CDecrypt (often styled cdecrypt by @FIX94) required this unique console key to convert encrypted digital titles into a loadable format for loaders like Loadiine.
⭐⭐⭐⭐½ (4.5/5) Best for: Wii U modders, CEMU emulator users, and game preservationists.
Move the cdecrypt.exe executable along with its bundled .dll files directly into the encrypted game directory containing the .app and .h3 files. However, preservation efforts continue
In the shadowy crossroads of digital rights management (DRM), console hacking, and video game preservation, few tools have garnered as much quiet respect as CDecrypt . For years, the original version of this utility served as a scalpel for circumventing Nintendo’s layered encryption on the Wii U. But with the evolution of hacking methods, the shutdown of the Nintendo eShop, and the rise of emulation, a new iteration emerged: .
CDecrypt is used to "unpack" files that were downloaded or ripped but remain in their encrypted raw state.
Compiled from the ajd4096/cdecrypt-2 repository .
To use CDecrypt 2.0, you typically place the executable in the folder containing your encrypted data and run it via the command line. cdecrypt Use code with caution. Copied to clipboard title.tmd : The Title Metadata file.
