N64 Native PC Recompilation & Memory Studio

1. MIPS R4300i Disassembly

Pipeline: Fetch ➔ Decode ➔ Execute ➔ Delay-Slot Fold Delay-slot NOP & Branch Target Verified

2. Verified Clean-Room Native C

3. DK64 8MB Expansion Pak RDRAM Map

8,388,608 Bytes Active

Base OS/Engine (0-4MB) Expansion Pak RDRAM (+4MB) Active Heap Pool Historic Leak Buffer

Historical Context: Donkey Kong 64 notoriously required the physical 8MB N64 Expansion Pak because an elusive heap allocation bug crashed the 4MB base console. Clean-room static recompilation remaps the 32-bit big-endian N64 memory space into safe native 64-bit virtual memory pages.

4. Hardware Register Mapping & Safety

Clean-Room Symbolic Decomp vs Generative AI Synthesizer:

Manual Verified AST:

Strict structural recovery; correct endian swap logic; exact union alignment for actor state structs; no hallucinated pointers.

Naive AI Synthesizer:

Mishandles MIPS branch delay slots; hallucinates standard malloc() pointers; crashes on N64 32-bit hardware register traps.
