1244556688/Mycoolos — reverse-engineered prompt

Build me a tiny hobby operating system from this repo that I can boot and play with locally. I want it to start up cleanly, load a simple kernel, show a basic graphical screen instead of just plain text, and support very simple mouse input so I can tell it is alive and responding.

Please wire up whatever is already here so the whole thing actually builds and runs end to end with a straightforward command, and make sure the boot setup, kernel code, graphics, and mouse pieces all work together. If there are duplicate or half finished files, pick the sensible path and clean it up. Add just enough comments so I can follow what is happening.

I would also like a simple way to test it in an emulator, plus a short note telling me how to build it and what I should expect to see on screen when it starts. If you need to, look up current docs online and make reasonable choices to get it working.
