Organization

Main Files

Silent Hill is comprised out of 3 main files. The executable, and two file containers: SILENT. and HILL..

HILL. exclusively contain audio and FMVs while SILENT. contains the overall game data including all the important pieces of game code which are overlays.

Code Files Explanation

Alongside the executable, the most important pieces of code are inside the 1ST folder in SILENT.:

• The actual executable named SLUS_007.07, hereby referred to as main. The main executable in Silent Hill serves only the purpose of initialize the load of B_KONAMI.BIN and BODYPROG.BIN while also displaying the content warning image.
• An overlay responsible for loading the some of the assets of general the game (as it is Harry's model and animations and the fonts) and display the Konami and KTCE splash screens B_KONAMI.BIN.
• The overlay containing the main engine and general game code, named BODYPROG.BIN.

The rest of the overlays are in VIN folder, which include:

• STREAM.BIN - used to play video files.
• OPTION.BIN - used for displaying and handling the logic of the options menu.
• SAVELOAD.BIN - used for displaying and handling the logic of the save and load menu (not responsible for handling memory card state or save data, those are in charge of the engine).
• STF_ROLL.BIN - used to display credits.
• MAP#_S##.BIN - maps scripts and AI logic, loaded in the game playthrough order (e.g. MAP0_S00.BIN - is the first file from the game start up to the cafe, MAP0_S01.BIN is loaded next).
• • _S## it is very likely a shortage of STAGE. While the second number is clearly intended to represent the stage index the first number is always 0 excepting in the European release where it uses different numbers from 0 to 5 (skipping 1 for unknown reasons) in order to represent the language.

Main Folders Structures
