The Free TOWNS OS project aims to provide a copyright-free FM Towns OS for running free games and developing new applications without copyright concerns. The Tsugaru OS can run popular free games like Panic Ball 2 and VSGP without relying on files from the original Towns OS. To use it, you can boot from the provided files, or mount an image and run it from a virtual drive without needing CMOS setup. However, building the Tsugaru OS requires tools like Python and Visual C++, and precise setup instructions are necessary. The project acknowledges contributions from various developers and the FM TOWNS community.
