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 standard and TurboWarp-modified Scratch 3 projects on Wii hardware.
• Custom blocks exclusive to Scratch Everywhere!
• Mouse input - Controlled via the Wii Remote and Sensor Bar.
• Audio - Support MP3, Ogg Vorbis, and WAV formats.
• Framerate - Adjustable through TurboWarp's project settings.

Installation

Download scratch-wii.zip from the Releases page.

Unzip and place the apps folder inside the root of your SD card.

Put Scratch projects into sdcard:/apps/scratch-wii/.

Launch the app from Homebrew Channel on the Wii.

Porting Scratch to the 3DS (NateXS)

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:

• "Streamed Sound" is not supported. Any sounds in "Stage" will load and play like a normal sound.
• Sounds may fail to load if the length of the sound is too long, or if there's too many sounds loaded at once.
• Cloud Variables aren't currently supported, but likely will be in the future.
• The first controller connected will be the only one that will work.
• If you're using a PAL Wii, you must use 50Hz.

Changelog

Beta Build 23

• New Features
  • Scratch Everywhere! Custom Blocks!
    • This actually isn't a new feature, but we never talked about them at all so I'll talk about it here :)
    • Similar to TurboWarp's is compiled? and is TurboWarp? blocks, We've made a few new blocks that Scratch Everywhere! can understand!
    • You can still upload your projects to the Scratch website when using these new blocks!
    • is Scratch Everywhere!? block returns true if your project is running on Scratch Everywhere, and returns 0 otherwise.
    • is New 3DS block returns true if your project is being played on a New 3DS, returns false otherwise.
    • Scratch Everywhere! platform returns the platform your game is being played on (3DS,Wii,etc).
    • A project containing these blocks can be downloaded here!
  • Unpack project option in project settings!
    • Instead of the normal way the runtime works by putting the entire scratch project in memory, unpacking a project eliminates this by only loading things when it needs to!
    • Unpacked projects are great for large projects, and projects with a ton of images!
    • Depending on the speed of your SD card, unpacked projects can run way faster than normal projects!
    • Unpacked projects will have a lightning symbol next to it, and will appear towards the bottom of the project menu.
  • Bottom Screen option in project settings!
    • For 3DS, you can enable any project to be played on the bottom screen instead of the top screen!
    • Great for projects where the touchscreen plays a key factor in gameplay!
    • This also means Scratch Everywhere! can be used with a broken top screen! (I know at least 1 person will be happy about this)
• Runtime Changes
  • If you have a project in your Scratch Everywhere! folder named project.sb3, the project will now automatically run when opening the app.
  • Changed D-Pad controls in Main Menu
    • NOTE: If you're using a Wii Remote, this means you now have to use the remote sideways to navigate the Main Menu.
  • Added more splash text to the Main Menu
  • Fixed a ton of memory leaks under the hood
• 3DS Changes
  • Fixed buttons in the Main Menu sometimes not loading correctly
