Case study

LSD: Dream Emulator — a matching PlayStation decompilation

LSD: Dream Emulator reconstructs the Japanese PlayStation release SLPS-01556 in documented C source. Its build uses the user's retail disc and Psy-Q SDK inputs, then checks the output SHA-1; the author reports that every game function is completed and the executable matches byte for byte.
