This injector will unlock the QR Code exclusive content in Dragon Ball Fusions and should work for all regions of the game.
In Japan, the game had option to QR Scan promotional codes from magazines to unlock extra characters, costumes and a quest.
That QR Scanning functionality was removed from the Western version however of the game due to Nintendo of America's policy that forbids
developers from ever using QR Code Scanners in their games, after the game Cubic Ninja which had QR Scan feature led to 3DS hack exploit.
Despite this, the content is still inside the game files and fully translated too! Just normally inaccessible.
One possible workaround was to export the save to JP version of the game, scan the QR codes, save the game and then export the save
back to the western version of the game, but that requires downloading the JP version of the game and is more time consuming.
As such this Injector was made to relatively painlessly unlock the QR content in the western versions of the game.
Credits for the injector go to an Anonymous author on 4chan.

There are two necessary requirements for this to work:
1. You must have reached World 3 in the game and unlocked the Spaceship.
2. Your save must be from the game running the 2.2.0 update.
It's very important that those two conditions are met, especially the second one, because if not it can potentially mess up your save.

How to use it:
1. Extract your Dragon Ball Fusions save with JKSM (JK's Save Manager), which you can easily find online if you google for it.
2. Move your extracted save to PC.
3. Run the Injector and select the options you want (most likely all 3), press the "Do It!" button and navigate to the folder with the save.
It should then modify the saves to unlock the QR Code-exlusive content (and create a backup) which is as follows:
- 3 New Characters:
Tanks - an EX Fusion of Tapion and Future Trunks
Great Satanman (Herculeman in US/EU) - an EX Fusion of Mr. Satan (Hercule in US/EU) and Great Saiyaman
Gorus - an EX Fusion of Adult Goku and Beerus

- 4 New Costumes:
Beerus' Outfit
Whis' Outfit
Cabba's Outfit
Hit's Outfit

- 1 New Quest:
In World 4, at Fortuneteller Baba's palace you will be able to find Future Gohanks - an EX Fusion of Future Trunks and Future Gohan.
By talking to him he will offer you a quest to beat him, if you succeed, he will join your team.

Changelog:
