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, NDS, PSP, Vita, Switch and PS4.

Features

• Runs Scratch 3 projects, including those tailored in modded clients like TurboWarp.
• Custom blocks exclusive to Scratch Everywhere!
• Mouse input - Hold L to enable, D-Pad to move the mouse, and press R to click.
• Audio - Support MP3, Ogg Vorbis, and WAV formats.
• Framerate - Adjustable through TurboWarp's project settings.

Installation

Download the scratch-nx.nro file from the Releases page.

Place scratch-nx.nro in the sdcard:/switch/ directory.

Put Scratch projects into the sdcard:/switch/scratch-nx/ folder.

Launch Scratch Everywhere! via the Switch Homebrew Launcher.

See readme for controls.

Porting Scratch to the 3DS (NateXS)

Limitations

General:

• Text and embedded bitmap images will not show up on vector images containing it.
• Most Extensions (e.g. music extension) are not yet supported.
  • Only the Pen, and Makey Makey extensions are currently 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).

Switch:

• 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.
