Most versions of Ggos 0.9.6 are open-source (GPL). But some customized builds (e.g., for game consoles) may include proprietary code or bios files. Distributing those modified versions is likely copyright infringement. Stick to the clean, unmodified open-source release.
If you want to proceed with customizing your operating system, let me know: What do you plan on playing most? What are your hardware specifications (CPU, GPU, and RAM)?
Ggos 0.9.6 isn't about bleeding-edge features—it's about reliability and nostalgia. Whether you're maintaining an old machine or testing software history, downloading this version connects you to a pivotal moment in the software's evolution.
