WUPify

WUPify is a simple batch tool for cleaning and preparing No-Intro Wii U CDN folders for WUP Installer and Cemu.

Cemu can use the prepared folders directly, so there is no need to decrypt them first. The same prepared folders can also be copied to your Wii U SD card for installation with WUP Installer.

Dependencies

• Python 3.10+
• cryptography

On Windows, Launch WUPify.bat automatically installs cryptography if it is missing.

How to use

Windows

Put these files in the main folder of your Wii U CDN collection:

WUPify.py
Launch WUPify.bat

Then double-click:

Launch WUPify.bat

WUPify scans the subfolders recursively and prepares the titles it finds.

Command line

python WUPify.py --path . --recursive

Preview the changes without modifying any files:

python WUPify.py --path . --recursive --dry-run

Use python WUPify.py --help to see the available options.

Usage

• Cemu: use the prepared title folder directly.
• WUP Installer: copy the prepared title folder to SD:\install\ on your Wii U SD card.

A prepared title folder uses the standard WUP layout:

00000000.app
00000001.app
...
title.tmd
title.tik
title.cert

WUPify leaves titles that are already ready untouched and reports any title it cannot prepare safely.
