Smash Wii U All save data gone, any hacks?

[LoudCloud]

So long story short I lost all my data and had to start again. The memory was corrupted, I couldn't play anything and nothing online helped, so I deleted the save files and the game worked again.
The problem is that all my stuff is now gone. All the unlocked characters, stages and most painfully all the custom gear and costumes that I've worked my *** off these past few days to obtain.
I'm really not in the mood to go through everything again so are there any hacks to unlock everything in the game? Like one of those 100% complete hacks that Brawl had? Anything that unlocks things faster would suffice. I'm getting pretty desperate here.

I can't help you with any hacks, but I do know a rather quick way to get all the characters again.
Play Special Smash: Stamina 10, Mega, Flower, Curry, Fast.
You can't just turn on 4 CPUs though, you have to be in the match for it to count. Doesn't matter if you lose.
Aside from pressing start to cycle through the menus, it doesn't require much of your attention and you can unlock all the characters in 30 minutes while doing something else in the background.

Characthers and stages are fairly easy and fast to get. As for the custom gear, there are some ways to farm it as HYP3R mentionned above. Crazy Orders is my favorite gamemode to farm tons of custom gear.

(Also, you didn't mentionned trophies :O)
