Here's the folder structure. Nothing is in the sub folders.
The game appears to be intact. It has the videos and music, sequenced and streamed, so far anyway. The option menu's controller configuration is not selectable, because pressing Esc gives you the controller config from gametap. The audio emulation is quite poor and the music sounds way off, much like it does in the emulators we know of. The game if a little too filtered. Many textures would look better without filters, especially the crosshair and the text. The game is fixed at 800x600 resolution.
