Features:
- Dump a Wii U Disc in WUD (uncompressed) or [WUX](https://gbatemp.net/threads/wii-u-image-wud-compression-tool.397901/) (loseless compression) format (including the game.key)
- Dump the GM Partitions (Game, Updates, DLCs) of an WiiU 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 DiscID of a game can be found on the disc (e.g. WUP-P-ARDP for the EUR version of Super Mario 3D World).
## 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" "C:\wudump\game.wux"`

## Building using the Dockerfile
It's possible to use a docker image for building. This way you don't need anything installed on your host system.
```
# Build docker image (only needed once)
2021-10-16 13:27:19 +02:00
docker build . -t WUDD-builder
2021-10-09 00:58:55 +02:00
# make
2021-10-16 13:27:19 +02:00
docker run -it --rm -v ${PWD}:/project WUDD-builder make
2021-10-09 00:58:55 +02:00
# make clean
2021-10-16 13:27:19 +02:00
docker run -it --rm -v ${PWD}:/project WUDD-builder make clean
2021-10-09 00:58:55 +02:00
