Since I only have an 8 GB Wii U which doesn't have the capacity to store all the downloadable games I own, I thought it would be useful if I could make backups of them all on my SD card and reinstall them from there whenever I need. That seems like it should be faster than having to redownload them from the eShop every time. And it would be future-proof, since it's clearly only a matter of time before Nintendo shuts that down entirely.
However, it's been a real struggle to figure out how to do this. I found a tool called Dumpling that can dump my installed titles in the form of their actual decrypted files. Which is great for datamining, but from what I can gather, it's not possible to reinstall them in this state.
If I understand correctly, I'm then supposed to repack them with a tool called NUSPacker, but the first post of its dedicated thread scares me. It actively warns people that this tool is experimental and should never be used to install anything to the SysNAND, which I believe is all I have. (Correct me if I'm wrong. I'm still new to Wii U modding.) And it also has a link to something called a patched IOSU. I don't know if I have that already or require it. It also sounds like this tool may need an encryption key, but I don't know where to find that either. In short, I have no idea how I'm supposed to use NUSPacker and even if I did, I'd never do it without someone first confirming that it's indeed the right tool for the job and has no risk of bricking my Wii U.
If I understand correctly, the last step of the process would then involve using another tool called WUP Installer GX2 to reinstall the repacked games.
So am I right that this is the recommended way to handle this? And that contrary to the warning I found, it's completely safe to do? If so, how do I use NUSPacker? If not, what am I supposed to do instead?
Note that I'm using Tiramisu. I didn't bother installing Aroma, but I can take care of that if it's necessary.
