Wii U USB Helper


Big Thanks to Kazegaya For making this very Nice Program!!! 

Update 30/10/16 Open Beta Started !

Alright guys, since the first open beta is now live I’d like people who are interesting in helping me debug the app to send me a pm !
But before you do please keep in mind that the application is still a WIP, and you will definitely encounter bugs. But isn’t that the very purpose of a beta :P ?
Anyway, see you soon !

What does it do ?

This program is intended to help you download games from NUS and install them on your Wii U. It’s a bit like NUS Grabber except that it does not rely on any external tool, almost everything has been reprogrammed from scratch with ease of use in mind.
What does it look like ?

Here is a screenshot from the latest debugging version :

What will I need to use it ?

You will need to provide the app with a certain RAR Archive(not individual tickets) of tickets from you know where to make it work.
Don’t ask where to get it, it’s against the rules !

How do I install downloaded games ?

I recommend that you use this tool. Just use the app to copy the games to you SD card and then launch the tool to install :)
Thanks for reading !

Thanks to @gbamix for the awesome logo !


How to play Mario Kart 8 DLC tracks

How to play Mario Kart 8 DLC tracks in Loadiine in a quick/dirty way


jebediah Over at Gbatemp Said This

Ok I cannot make a fool-proof tutorial about this just now because I didn’t do much troubleshooting, but feel free to follow my steps if you want to play the 16 new DLC tracks of Mario Kart 8 running in Loadiine.


  • Offline only obviously
  • New tracks are actually swapped with original ones
  • Music from the new tracks can’t be played, so you can choose between the music from the tracks you replace, or no music at all (not so nice)
  • Not sure if battle mode works

Tested setup

  • Firmware 5.3.2 EU
  • Mario Kart 8 EU updated to 4.1
  • Loadiine 4.0 with Smash Bros Mode (Wii Maker mode doesn’t work with MK8 4.1 update)


1. Get your hands on a dump of the DLC 1 and 2, Google It

2. The new DLC tracks are contained in separate folders within the “course” folders. For instance, the files for the Ribbon Road track are in a folder named “Dagb_RibbonRoad” in “course”

3. On your SD card which contains your MK8 game files, locate the original track you want to be replaced with any desired DLC track. They are in SDCard/wiiu/games/MK8foldername/content/course.

NOTE: They have prefixes which will help you figure out what system the track was originally released on. For instance, “G3ds_DKJungle” is the DK Jungle track from the 3DS system, and “Gu_Techno” is the Electrodrome track first released on the Wii U.

4. Delete every file in such folder except for the .bars file which is the music track, unless you want to play without the music.

NOTE: If you replace this file with the .bars file from the DLC track and rename it, the game will crash upon loading the track. But if you just delete it and do not replace it, the track will still load, just without background music. So if you’d rather have a wrong tune than none, you may want to pick tracks whose music shares a similar mood.

5. Paste in there all the files from the DLC track folder, except the .bars background music file, and take note of which track you swapped it with.

WARNING: in the dump I used, the Mute City DLC track had one file mispelled as “course_muuntO.byaml” instead of “course_muunt.byaml”, so be sure to rename it accordingly, or the game will crash upon loading the track.

6. Copy all the folders found in the “mapobj” folders contained in the DLC dump, and paste them into the MK8foldername/content/mapobj folder on your SD card.

7. Put your SD Card back in the Wii U and load your hacked MK8 game!

8. If that was worth it, say thanks! or just press the Like button :)


It’d be nice to be able to play the DLC background music, I just haven’t messed around long enough to figure out a way just yet.

Anybody knows what are the “battle_muunt.byaml” and “course_muunt_200.byaml” files for? For some reason they are not here for every track.
