LSD: Dream Emulator: a matching PlayStation decompilation

lsd-decomp reconstructs C source for the SLPS-01556 PlayStation release of LSD: Dream Emulator and checks the rebuilt executable by SHA-1. It documents the dream graph, links, randomness and engine systems with function addresses, alongside emulator-based observations; the author reports that all game functions rebuild to the retail bytes.
