Wanted to try and recreate this setup, to understand the funny code behind this :) Press q to render cart Press w to render spritesheet After digging through some of the scripts, (I think) it’s a .p8 png cartridge represented either RRGGBBAA or 0xRRGGBBAA in hexadecimal. This version only supports RRGGBBAA format. If you do want to import your own carts, then go to https://xeltalliv.github.io/ScratchTools/Img2list/#hc2, then set the “Mode” to “hex combined RGBA.” Import the file you want, the download the txt output. Import the txt into this project (https://scratch.mit.edu/projects/1321765796/), and copy the output. In the future, I might think about making an parser that converts to bytecodes (that’s actually compatible with the original projects) to finish this project. Thanks to @Geotale for original project, Google Gemini for helping me sort of understand picolz/PXA compression (the old version), @electricgryphon for example cartridge “Gryphon 3D Engine Library”, and @zep for example cart “The Adventures of Jelpi”. why did I make this
