Bros OS — a proprietary x86_64 operating system built from scratch in Rust, continued from the original BerkeOS repo. 4 years of work, ~95k lines of code, 513 source files. Custom filesystem (DefneFS, named after my girlfriend), forked GRUB2 bootloader (BAHAR), full TCP/IP stack, modular graphics, USB XHCI, 185+ shell commands. Built with OpenCode + Ollama (MiniMax 2.5, DeepSeek) and heavy OS Dev Wiki usage. Closed source because the code was stolen from the original BerkeOS repo. Patent pending. Goals: GUI, more drivers, bare metal stability, native game.
