This is a super old project that I hardly remember how to use. You can open apps with the grid icon at the bottom right. "AZ TEXT EDITOR" and "BASIC TEXT EDITOR" are two failed attempts at making a text editor in the VM. I regrettably lost the source code to all of these. If you want to go through the pain of making an app in this, look through the "OPCODES" list and the "virtual machine" sprite, as I left little documentation. I don't remember how to add apps, I think I added the existing ones by manually editing the lists. You can drag the edges of a window to resize it. When in fullscreen, scroll to show the title bar. The minimize button doesn't do anything. Consider this to be a demonstration of a few interesting Scratch techniques. All of the apps run in the Soup OS Virtual Machine, and were assembled from assembly-like text files (which I lost) into a usable format using the assembler sprite (I got halfway through or so with making a disassembler when trying to recover the source code). Window graphics are stored in a text "command" that has all the info needed to render the window without the app's intervention. Window rendering has two modes, fullscreen, which draws a window command without restrictions to the stage, and windowed, which crops everything to be within the bounds of the window.
