RedStar OS 3.0 is a national Linux distribution from North Korea, designed primarily for the DPRK's intranet, Kwangmyong. The modified version, RedStar OS 3.5, claims to enhance the original by removing spyware and providing easier access to root privileges. The author faced challenges in accessing the system, implementing a 64-bit kernel, and connecting to the broader internet due to the OS's limitations. Attempts to run the game Tux Racer were unsuccessful due to compatibility issues, resulting in a system with only basic applications available. The overall experience highlighted the shortcomings of RedStar OS 3.5 in terms of practical usability, especially for gaming.
