Back in 2015, I made a tool to bundle Scratch projects with a modified copy of the editor, letting people share them as standalone Flash games. Much like Scratch 2 and Flash itself, this is completely obsolete, but similar projects like HTMLifier are available for Scratch 3.
Thank you to everyone who sent me encouraging feedback; as my first "real" coding project, it meant a lot to me.
The final version is here, and the "Create Projector" workaround is here. Please don't look at the code, lol.
GPL v2, as a derived work of Scratch 2. I was also asked to include the following: Scratch is developed by the Lifelong Kindergarten Group at the MIT Media Lab. See http://scratch.mit.edu.
