Scratch Everywhere! is a work-in-progress runtime written in C++ that lets you run Scratch 3 projects. Initially developed for the 3DS, it now supports a number of 6-8th generation consoles including Wii, Wii U, Vita and Switch.

Features

• Runs Scratch 3 projects, including those tailored in modded clients like TurboWarp.
• Custom blocks exclusive to Scratch Everywhere!
• Mouse input - Mapped to the Wii U GamePad touchscreen.
• Screen modes - Currently projects display identically on both the TV and GamePad.
• Audio - Support MP3, Ogg Vorbis, and WAV formats.
• Framerate - Adjustable through TurboWarp's project settings.

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.

Limitations

General:

• Text and embedded bitmap images will not show up on vector images containing it.
• Extensions (e.g. pen and music extensions) are not yet supported.
• Some blocks may lead to crashing/unintended behavior (Please open an issue if you know of a block that's causing problems).
• Performance is poor when using many (~30+) clones (memory management issue).

Wii U:

• "Streamed Sound" is not supported. Any sounds in "Stage" will load and play like a normal sound.
• The first controller connected will be the only one that will work.
