WUDD - Wii U Disc Dumper
Inspired by wudump from FIX94.

Features:

Dump a Wii U Disc in WUD (uncompressed) or WUX (loseless compression) format (including the game.key)
Dump the GM Partitions (Game, Updates, DLCs) of an Wii U Disc as .app,.h3, .tmd, .tik, .cert files
Supports dumping to SD (FAT32) and USB (NTFS only). When dumping to SD the files get slitted in 2 GiB parts.
Files will be dumped to /wudump/[DISC-ID]/. The disc id of a game can be found on the disc (e.g. WUP-P-ARDP for the EUR version of Super Mario 3D World). If WUDD fails to determine the disc id, "DISC" with a timestamp will be used instead.

How to merge splitted files

When you dump a .wux or .wud to the SD card it gets splitted into 2 GiB parts (FAT32 limitation). To merge them you can use the copy cmd tool.

Example: copy /b game.wux.part1 + game.wux.part2 game.wux

Dependencies

Requires an Environment (e.g. Tiramisu or Aroma) with MochaPayload (Nightly-MochaPayload-20220725-155554 or newer)
