Hacking [QUESTION] Extracting system apps

[trainboy2019]

Hi, I made a nand backup of my Wii U and extracted the contents of it, since I wanted to extract the assets of the system apps. But I can't figure out how to do it. Does anyone know how to do this or if it's even possible?

You're probably looking for SARC and Yaz0 tools. I'd tell you where to get them, but I'm not sure which exact tools you might need due to format differences and possible endianness.

No, There's no magic number that matches those files. I'm talking about the .app and .tmd files in nand/titles/****/****/content

That doesn't sound like a nand dump.

Use CDecrypt though.

Are you possibly talking about Wii/vWii, not Wii U?

I dumped the nand with nanddumper and used nand extract to extract the files in it. also, what's the cetk for system titles?

What you extracted was the vWii titles. If it is a Wii U title you want to modify, you need to extract the MLC, not SLC.

That tool you used extracts the vWii partition off the full wii u nand.

I did mine through FTP, but I think you can use this tool.

Never used it however.
