"java -jar JWUDTool.jar -in "game.wux" -out "extracted" -extract all " is a command from the github page i downloaded it from, im not sure what im missing
edit: ive tried changing "extracted" to game.app but it makes a folder called game.app

Let me go over the basic trouble-shooting.

in the command

java -jar JWUDTool.jar -in "game.wud" -out "extracted" -extract all

Did you actually specify the output folder within the "extracted" paramater?

Secondly, is the game.key file created, and formatted correctly, also in the correct placement?

Also of course the "extracted" argument creates a new folder. That specifies the output .-.

It only clearly outlines it in the README

Anyways why are you even using WUX / WUD files? There are so many other alternatives that are WAYYYYY better.

NUSspli as an example.

im dumping my own game for a backup and installing the .app my game key works i assume as i can compress and decompress it, i also understood that it creates a folder but bc i was getting the formatting error i tried other methods

So you're missing a key. Let's look at JWUDTools Readme: https://github.com/Maschell/JWUDTool/blob/master/README.md#Usage

usage:
-commonkey <WiiU common key> Optional. HexString. Will be used if no "common.key" in the
folder of this .jar is found

I can't see this argument at you command string, so do you have a file called common.key containing the Wii U common key in place? If not that's your issue.

i can compress and decompress it

But what you want to do is decrypting, so you need the Wii U common key.

//EDIT: Also what @Korozin said. You need the games key and the common key. Also from the readme:

-titleKey <WUD title key> Optional. HexString. Will be used if no "game.key" in the
folder of the wud image is found

//EDIT²:

im dumping my own game

So you're doing things more complicated than needed: WUDD is able to dump directly to .app format and you need no keys for that.

i had both the common and my game key, i ended up dumping both that and the app in the end lol

Quick question. But how did you make your .key files? Because if I remember correctly you have to insert the Key as Hex data, you can't just paste it into something like Notepad and call it good. That may be a factor where it went wrong.

You also need to be aware of which key you're using in the game.key file as sometimes there's multiple versions.

thats probably it, i used notepad and changed the extension from .txt to .key, it worked in wizard u so i thought it was valid
