Scanline display drawer that I made for fun, runs horribly so I would suggest going to TurboWarp or PenguinMod or whatever Scratch mod you prefer, to use this project. V1.0.1: Fixed the notes & credits. V1.0: Release.
This allows for drawings to be displayed in a VERY EXCELLENTLY AMAZINGLY crisp 480p quality, like I said, it's pretty crisp. Currently, you're not able to modify VRAM entries, unless you want to get funny with the code, so it's just a glorified noise generator that gets drawn progressively, but it has it's potential.
