Shin Megami Tensei III: Nocturne: matching PS2 decompilation

Shin Megami Tensei III: Nocturne reconstructs readable C source for the US PlayStation 2 release and checks the linked executable against the retail SHA-1. Its build also assembles annotated VU microcode and retains assembly for unfinished functions. The author reports that a dated snapshot recovered 66.32% of game-code bytes from C.
