Important notice Please always use the app's built-in copy feature which will automatically remove special characters from the path which would otherwise result in a "install of title 00000000-00000000 failed" error! 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. It comes with full DLC, VC (those require signature patching) and Updates support, and file hashing to ensure your downloads are always perfect The application is also compatible with Cemu, and Citra and will allow to play WiiU and 3DS games directly on your computer! I've seen a lot of guides which tell you to manually unpack the content to use it with CEMU but you'd be better off using the play button which will take care of everything in just one single click! Updates and DLC will be applied automatically so long as you have downloaded them! You can easily manage your library of games, and copy them to your SD in one click ! What about 3DS games? Despite the name, Wii U USB Helper can also download 3DS games. However those can only be played on a regular 3DS, you cannot play them on your WiiU or CEMU. Check out the little colored square at the top right corner of the icon to know what console a specific title is for. Red means 3DS, blue Wii U.

That title key site is the best option Some games, like CoD are not available on NUS, and won't show up in the app, it's perfectly normal. To install eShop-only games and DLC, you will have to input the address of that site. DO NOT ASK FOR THE ADDRESS OF THAT SITE, IT IS NOT INCLUDED IN THE APP. Why are some games available on that site but not on the app? If the titles you are referring to are available on the eShop, then please allow some time for them to show up in the app. In fact, the application needs to cache a lot of data to provide you with banners,covers, descriptions... If one game has not been analysed by the app before being added to the site, it will not show up until its data has been collected, which can take up to 24 hours. Why are the sizes displayed in the app bigger than the ones reported by Windows? Warning: Spoilers inside! Without getting into too much details there are two ways display sizes. Either you decide to group bytes (the smallest group) by packets of 1024 bytes, 2^10 (1 KiB), or 1000 bytes, 10^2(1 KB). Windows actually uses packets of 1024 bytes but mistakenly uses the KB unit, instead of the KiB unit. My app reports sizes as true kilo bytes. Why is that ? That's because it's the unit storage manufacturers use too (because it allows them to print bigger numbers) so it makes calculations easier. One big advantage is that if your SD card has a size of 8GB and the app displays a game at 7.8GB then you know it will fit just fine without having to check to size reported by Windows (provided there is enough space left of course). If you were using KiB (like Windows) then your SD card would only appear to have 7.45 GiB (reported as GB by Windows) of storage available. Of course that's doesn't change the amount of space available, just your perception of it. 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 Always prefer using the app's feature to copy games rather than copying them manually because it will check the integrity of the files before copying them to the SD. What tool can I use to transfer games via the network? This Can I import games downloaded from another tool ? Warning: Spoilers inside! Yes. To do so, please go to the "Batch Commands" tab at the bottom of the main window and select "Import Games". You will be asked to select the root folder containing the games you wish to import. Please note the application will only check the first sub-folders of this path. Example: ->GAMES/(The folder you specify in the app) ---->Game1/ ---->Game2/ If (Game1) and (Game2) contain at least 'title.tmd' then they will show up in the list. It is possible that they won't show up if you already have downloaded the games, even partially, with the app. Finally, the games must be of the same region as the app. Please also note that importing a game will MOVE the folder. That's all you need to know Troubleshooting Here are the most common issues you can encounter and how to solve them. I have installed my own version of CEMU but it keeps getting replaced Go to "Emu. settings" and uncheck "Automatically update CEMU". The application always creates a shortcut on the desktop, even when I delete it To change this behaviour enable "Prevent the Updater from generating a shortcut" in the Advanced Settings tab. When unpacking a game, the window appears to freeze Depending on the title, the extraction process can be quite lengthy. This is a normal behavior, please allow some time for it to complete. "The method is not implemented" Most likely you have specified a wrong ticket archive. Just delete %localappdata%/Hikari06 and start the app again. Updater.exe crashes on start. This happens if you have installed the app in a location which requires admin permissions (like Program Files) and your OS won't allow the updater to spawn an elevated process. Just install the app in a neutral location such as your personal folder and off you go! HTTP 404 not found Most likely the eShop in under maintenance. Please try again later. I've just downloaded a game and it does not appear in the "Downloaded" section. Sometimes the list may not update instantly. You can still copy or play it with the app, it just won't be sorted in the proper category right away. Restarting the app will solve the issue. Special thanks Thanks to all the testers who helped me make the app a bit more stable ! Thanks to @cearp, @DanTheMan827 ,@crediar ,@FoxMcloud5655 for their respective work which made this possible ! How can I get the source code ? Versions up to 0.6.1.57 of the application were using libWiiSharp, a GPLv3 library. Consequently, to comply with the terms of the GPLv3, the source code of v0.6.1.57 is available so long as you contact me and ask for it. I'll do my best to fulfill your request as soon as possible. Only inquiries sent to this address will be answered. Thanks for reading!
