MIPS Cross-Compilation for Custom VMs

This skill provides a comprehensive framework for porting complex C applications, like Doom, to custom MIPS virtual machines and emulators. It guides users through the critical process of analyzing target VM internals—including syscall interfaces, ABI requirements, and memory constraints—while providing systematic strategies for freestanding compilation and standard library replacement. By offering detailed debugging tactics and specific compilation flag references, it helps developers bridge the gap between standard C expectations and restricted runtime environments, ensuring successful execution in environments where standard operating system services are unavailable.
