Could you build this?

No Creating a custom operating system capable of running OpenJDK, Mesa, OpenGL, and Minecraft is an enormous systems engineering feat requiring deep OS kernel, libc, and graphics driver development.

What it would actually take: This project requires building an entire OS from scratch (kernel, memory management, scheduler, virtual filesystem, POSIX compatibility layer), porting a C standard library (like mlibc), porting a complete JVM (OpenJDK), and porting Mesa with software or hardware OpenGL drivers. It demands years of specialized low-level systems programming expertise across OS architecture, cross-compilation toolchains, and graphics stack internals.
