This skill provides a comprehensive framework for porting complex software—exemplified by projects like DOOM—to constrained MIPS-based virtual machine environments. It focuses on overcoming the technical hurdles of creating freestanding executables, such as implementing custom syscall interfaces, building lightweight standard library replacements, and configuring toolchains with specific flags like -ffreestanding and -msoft-float. By emphasizing systematic environment analysis and iterative verification, it ensures that compiled binaries not only execute instructions but successfully produce the intended functional output within the target VM.
