I'd like to find someone to make this with some day but here are some graphics I made for fun for a binding of isaac gameboy thing. Some would need reworking because I forgot one of the colors needs to be transparency though.
I had to share my madness of learning how this background compression works so I could modify it a bit. I always knew how it worked for the most part but I never changed the variable names to be a bit easier to read and now I'm trying to use it in a scrolling engine.
I attached the picture of my wall. My daughter thought I snapped lol.
Edit: this somehow ended up on the main topic instead of background compression so I added what it was
Let me tell you, the paint is a huge pain in the a$$! Took me 2 tries. I would suggest if you want to do it, get the wallpaper kind! Oh and if you do the paint, get a foam roller, not a regular paint roller lol.
