So basically, I bought a ton of games on the Wii U eShop before it closes. been playing golden sun and its a blast. I wanted to take it on the go, so I did a little research and using dumpling dumped the save file to my sd card, transferred to my computer, used a hex editor to convert the save into a format that would be readable by GBA emulators and my gba flash cart (ez flash omega). Took the game to work with me on my GBA before I realized the problem: I have no way to put that save file back on the Wii U to play there. I haven't hacked my Wii U, I'm thinking of buying a used one to hack after the eShop goes down but I don't want to hack my original one, too scared I might mess up and brick it. I'm not afraid to really get into the technical stuff, and I have hacked one of my new 3ds xl's so I'm at least familiar with some stuff but I am a Mac user so I am restricted by that. Looking to get a windows pc at some point but for now stuck on Mac. So basically I'm just looking for a way to overwrite the save on my Wii U VC golden sun with the .sav file on my flash cart without hacking the console. Also if this isn't going to work for any number of reasons that's fine, I'm mostly just curious if its possible. If not I'll just emulate the game with the rom dump I got from my Wii U already.
TL;DR can I inject a save file to a GBA VC title on Wii U without Homebrew or CFW?
Thanks for your help!
