LSD: Dream Emulator: partial PS1 decompilation and mechanics research

lsddecomp is an early decompilation of selected code from the PlayStation game LSD: Dream Emulator, with research on its dream timer. Its workflow extracts game data from the user's SLPS_015.56 file, rebuilds the executable and compares the result; the author describes the decompilation as assumption-heavy.
