Hello everyone. So I recently bought an external 1TB hard drive and y-cable for my Wii U and have been enjoying the fruits of that. I have sigpatched SysNand and Haxchii installed over brain age and the custom DNS set up to avoid updates. There's really only one thing I need help with, and that's taking my disc-based save files and preserving/converting them to use with the digital versions I'd like to install on my usb drive.
Kinda long:
So what exactly should I be doing to ensure I keep these three saves I've put serious time into?
Kinda long:
There are only three titles I really care about: Hyrule Warriors, Smash 4, and Xenoblade Chronicles X. I noticed that with WindWaker HD when I installed the game via WUPInstaller GX2 and ran the game from disc to check the save data that it was mysteriously gone! Honestly it's not a problem losing that game's save data, but if that happens with a game I care about I'm going to be really unhappy. I installed Twilight Princess HD at the same time, but never booted it up, so I did some testing. I copied over the save for TPHD from nand to USB (which apparently overwrote the installation for that game, so I reinstalled it with wupinstaller) and ran the digital version and my save was there just fine. From here on out apparently the USB save is the only one loaded when I play either the USB version or the disc version. Weird, right? I checked and the save files were on both storage devices, so I deleted the one on the nand. No change, the USB save is being used for both still. Works for me, but I'm not sure why that is. I've read tons of tutorials and, unfortunately, tons of conflicting information about how to do this and how not to do this. My own experimentation is a bit confusing, as well.
