Homebrew Wii U Plugin System

Wii U Plugin System
Enhance your Wii U!

WARNING: THIS PROJECT HAS JUST STARTED AND IS FOR DEVS AND PEOPLE WHO WANT TO PLAY AROUND WITH NEW THINGS. IT MAY BE BUGGY, FEATURE COULD BREAK AT ANY TIME, INTERFACES CAN CHANGE, AND MANY BUGS CAN OCCUR. THIS APPLICATION COMES WITH NO WARRANTY-
​

What is the Wii U Plugin System?

The Wii U Plugin allows you to load multiple plugins on your Wii U which enhance your experience. For example you can mod your games, use USB controller, swap your gamepad and TV screen and much more.

Support

You can find support in this thread or on the official Discord Server

Features

The project is still in it's very early days, but it already has basic functions to play with.

• The plugins will be loaded, even when you swap the running game.
• Support for up to 32 plugins at the same time.
• Each plugin can override up to 100 different existing system functions.
• Multiple plugins can override the same system functions.
• Plugins can register for certain hook (for example whenever an application was started)
• Plugins inherit the SD/USB access from the loader. All plugins have global SD and USB (FAT32 only) access.
• Plugins can inherit kernel access from the loader. The loader will be able to deny it to certain plugins.

Usage

Use the "Wii U Plugin Loader" to load plugins from the sd card. It is built to be loaded through the homebrew launcher, which can be either loaded with the browser exploit or haxchi.
Plugins needs to be placed into the following folder:

sd:/wiiu/plugins

You need to start this Application every time you reboot your console.
When you re-enter the homebrew launcher, the plugins will get unloaded.
This means it's not possible to combine this with other homebrews (yet).

Already created plugins

Currently the following plugins exist. They may have less functionalities then their "original" apps.

• INFO SDCafiine: (no ntfs support)
• INFO HID to VPAD: (no configuration, everything is mapped to the Gamepad)
• INFO WUPSPluginPlayground (Various other demo plugins)
• INFO Screenshot plugin
• INFO SwipSwapMe, a SwapDRC clone.
• INFO DiiBugger a Wii U debugger.

Contributing

Currently I'm working alone on this project.
I try to put as many thoughts and technical details / problem on the github page or on the Discord Server (#current-development)
So if you want to help, it's probably a good start to read the readme and the issues. You can also contact me whereever you like.
Any help will get much love!

Settings

Currently no settings are available, everything is still hardcoded as it's still at an early stage.

A big thanks goes out to Chadderz. The hard part about this is based on brainslug, it was a REALLY good base.

Thank you for your excellent work as always

 

[TotalInsanity4]

Dude that's awesome, props to you!

 

[kfrfansub]

Thanks dude

 

[Deleted member 424658]

The progress on this is absolutely incredible and I hope that it continues!

 

[JacobM]

Incredible work over the past 2 weeks! I've been following this closely and the rate of development is mind-boggling.

Since this project is based on Chadderz brainslug for Wii, do you think it is technically possible to "port" a simplified HID to VPAD for vWii Wii Titles? I know a lot of people have been dreaming about this feature and as the leading expert/developer in WiiU/HID interface you probably have a solid understanding of the limits of both the hardware and Nintendo's software.

Congrats and looking forward to testing this over the next few weeks!

 

[Diego788]

whoa!
this is awesome, i'll use it very often when I get a Wii U

 

[Kafluke]

Fantastic work!

 

[Osakasan]

This looks really interesting and may finally solve my pet peeve with Homebrew.
Thanks for your work, dude.

 

[lordelan]

This will be massive!

@Maschell: Will I be able to use HID to VPAD in Loadiine somehow?

 

[cucholix]

CFW patches + SwipSwapMe + HIDtoVpad = XCX perfect setup

 

[Masana]

Thank you very much for your applications, it's really great

 

[kfrfansub]

This will be massive!

@Maschell: Will I be able to use HID to VPAD in Loadiine somehow?

There is an option to enable HID controller in loadiine, no ?

 

[pwsincd]

Can't use it with other homebrew yet . Stated in the op

 

[Funkymon]

Could this be used for Amiiboo spoofing?

 

[wolf-snake]

Could this be used for Amiiboo spoofing?

I don't think that's easily doable outside of CEMU.

 

[Funkymon]

I don't think that's easily doable outside of CEMU.

I know it's done for 3DS, and if we can spoof the entire gamepad doesn't that mean we can spoof functions of it? Or is that just wishful thinking?

 

[Zarklord]

Could this be used for Amiiboo spoofing?

yes, BUT without a way to display custom graphics consistently in all games you would have no way to select what amiibo to spoof and other such things to it, i was actually working on this but abandoned the project due to the afformention issue.

So would it be possible on a per game basis? I'm thinking specifically of games like BotW where there's no storage of data necessary.
