PaperOS v1.0. First release.

First public release of PaperOS.

What's in it: launcher, file manager, Paint, a text-only browser, NES/GB/GBC
game emulation, an offline AI chat (myAI), a 3D mesh editor, and a full Lua
5.4 scripting console with its own hardware API.

Flash PaperOS_full.bin to address 0x0 (full flash, not incremental).
Setup instructions, SD card folder layout, and the full Lua API are in the README.

You'll need PaperEMU.extension for Games to work (also attached below), and
drop your own model.bin on the SD card root for myAI. Details in the README.

Known rough edges (also listed in the README): browser is slow on big pages,
myAI gives short and sometimes broken replies (small model, and it's
genuinely slow by design, not a bug), Lua hasn't been stress-tested on
heavy scripts yet. If you hit anything else, please open an issue with
what you did and what happened.
