Scratch Everywhere! for Wii U is a custom homebrew runtime that enables running most Scratch 3 projects directly on the Nintendo Wii U console. Developed in C++, it brings Scratch's accessible programming to platforms beyond its official scope, leveraging the Wii U's touchscreen and TV display.

Features

Runs Scratch 3 projects, including those tailored in modded clients like TurboWarp.
Mouse input is mapped to the Wii U GamePad touchscreen for intuitive control.
Projects display identically on both the TV and GamePad; dual screen features are planned for future updates.
MP3, Ogg Vorbis, and WAV audio formats supported, with streamed background music available.
The Username block returns the console's current Mii name within projects.
Custom blocks exclusive to Scratch Everywhere! are available, extending project possibilities.
Adjustable framerate available through TurboWarp's project settings.

Limitations

Currently, extensions such as pen and music are not supported.
Only the first controller connected is recognized when using the program.
Some blocks (color detection, say/think, certain visual/audio effects, cloud variables) are unimplemented or limited.
Audio loading may cause all sounds to pause if a new file is loaded during playback.
Expect occasional bugs, crashes, and performance issues with large projects or complex block usage.

Installation

Download the scratch-wiiu.zip file from the Releases page.
Unzip to sdcard:/wiiu/apps/ on your SD card.
Place Scratch projects in sdcard:/wiiu/scratch-wiiu/ folder.
Launch Scratch Everywhere! from the Wii U menu or Homebrew Launcher.

Beta Build 17

- Scratch Everywhere!
The name has been changed to Scratch Everywhere!
- That's Scratch Everywhere! with the exclamation point btw..
- It made 0 sense to keep the name Scratch 3DS as this is now on 5 different platforms...
- speaking of which...
Switch Port!
- For all 1.5 people who own a modded Switch, you can now enjoy Scratch games!
- Via pull request (#97)!
All new main menu screen!
- The Main Menu has gone through a huge refactor under the hood!
- It should be a smoother and better experience overall!
- It's still a work in progress, but now it should be a little easier to add stuff to it in the future!
Custom controls!
- In the Project menu is a new option to remap the controls of any project!
- Control mappings get loaded and saved to scratch-everywhere/'project_name'.json
  - Wii U is sd:/wiiu/scratch-wiiu/'project_name.json'
Runtime changes
- Sprite fencing has been implemented!
  - Can be disabled with TurboWarp or other Scratch mods.
- The Stop 'All' block now takes you back to the Main Menu instead of the homebrew menu!
  - Note: The Wii U will still exit the app, as it would freeze when going back to the Main Menu for some reason.
- Booleans (anything set to true or false) now doesn't get set to 1 or 0 by the runtime mistakenly
- Fixed a couple of crashes that could happen while loading
- Custom blocks with no definition now works as intended
  - Logging blocks created by Scratch Addons Debugging Addon can now be used.

  - For the 3DS, this means smaller file size, and you no longer need SDL2 to compile.
3DS Changes
- Fixed crash when closing the app
- Fixed audio cracking issue
- Sprites are no longer rendered in fractional positions, fixing some image weirdness
- Changed image filtering from nearest to linear
  - This fixes the image fuzziness and weirdness issues, with a tradeoff to some images looking slightly blurry. I might add a filtering option to the Main Menu in the future.
Wii Changes
