Notes:Clock Tower (SNES)

This page contains notes for the game Clock Tower (SNES).

Descriptions and ROM offsets for graphics

Add 200 if your ROM has a header.

List of animation offsets: 030000

Array with two bytes for each animation telling how far below 030000 that animation is defined. Animation IDs above 024D count from 040000.

Animations: 0308DA

Six bytes for each frame.

Byte 0,1	Sprite ID to use on this frame
Byte 2	Duration of current frame
Byte 3	X position to move to (From where the animation started)
Byte 4	Y position to move to (From where the animation started)
Byte 5	Flags (Flip entire sprite etc)

Every animation ends with FFFF.

Sprite tiles: 050000

This is where all the uncompressed sprite tiles are stored. The game loads four 8x8 tiles at a time.

List of sprite assembly offsets: 220000

Array with two bytes for each sprite telling how far below 220000 that sprite is defined. Sprite IDs above 07B1 count from 230000 and IDs above 1189 count from 240000.

Sprite assembly: 22264E

Five bytes for each tile in the sprite.

Byte 0	Flags for current tile (Flipping etc)
Byte 1,2	Tile ID of current tile (One ID for each 16x16 tile at 050000) or FFF0-FFF7 to use one of the 8 shadow tiles (0-7) in VRAM.
Byte 3	Y position of current tile
Byte 4	X position of current tile

Every sprite ends with FFFF.

Palettes

Palettes are somewhere beyond 010000. Jennifer's normal palette is at 01E812.

Room list

At 86FC in a headerless ROM there's a list of offsets for the content of every room such as which backgrounds and objects to load.

The current room ID can be read from 7FCF3D. At 7FCF25 is the room that gets saved to 0012 in SRAM.

ID	Offset	Room		ID	Offset	Room		ID	Offset	Room
00	C1C1	Elevator		14	A799	Hallway (Rubble & Elevator)		28	AB03	Cave (Ladder)

Sprite objects and animation list

The sprite objects such as the player, NPCs and room objects are located at 7E1870 in RAM. Every object starts with E2 and from there you can add these numbers to find the following values:

Offset	Value		Offset	Value		Offset	Value
02	Palette & flipping (One byte)		0B	Y position in room (Two bytes)		21	Animation timer (One byte)
03	Sprite ID (Two bytes)		1D	Offset of current animation frame (Two bytes)		26	Offset of first frame in current animation (Two bytes)
09	X position in room (Two bytes)		1F	Animation page (One byte)

To display an animation whose ID is above 024D, "animation page" must be set to C4. Otherwise, set it to C3. All movement like running or climbing is part of the animition frames. Bobby will use two objects simultaneously to display his body and scissors. Dan does the same for the two halves of his body.

This is the animation list found at 30000 (with no header):

Game text

At 020010 is a table of offsets to lines of dialogue. The offsets begin at the start of the table. The text is in Japanese, but the entries are helpfully in the same order as the Aeon Genesis translation patch, so this can be used for cross-referencing.

Additional dev text

Unused Hotspot Type

The code at $C05CC4 is run when a hotspot is clicked, checking RAM address $70 to find what the goal type is.

$72,$74,$76 and $78 have the hotspot arguments (specific to the goal type in question).

For type 0000 (Unused), $C05CCB is reached.

For type 0001 (Simple goal), $C05CE5 is reached.

For type 0003 (Left/ right goals), $C05CFE is reached.

Accessing the Debug Menu

Use the codes C0212B5A and C0212C21 to start the game in a debug loop. When in a room, you can press SELECT or L+Y for the following:

SELECT

Should print:

C X=%WD($%WH) Y=%WD($%WH)
J X=%WD($%WH) Y=%WD($%WH)
F X=%WD($%WH) Y=%WD($%WH)

... but the printing routine ($80E79D) is dummied out. The values loaded to $64-$6e are the following:

$64 Cursor room X
$66 Cursor room Y
$68 Player room X
$6a Player room Y
$6c Camera room X
$6e Camera room Y

L+Y

Enters the debug menu (Starting with "STRENGTH"). It works (or tries to) by printing text and asking for a value to be entered. The routine that gets a value ($80E8EC) is dummied out to always return $000A ($0010 hidden behind a bra instruction). You'll therefore need to set an execution breakpoint for address $80E8EF and set A to whatever you want to give as a response to the menu. Some commands will ask for a second value to be specified, such as MUSIC.

Without breakpoints, you'll just trigger option 10 instantly (ES2 hallway with Mary).

Free cam

Can be toggled in the menu, or set manually by changing RAM address $7F013E (only checked in debug loop).

Room $FFFF

Trying to load room $FFFF triggers code $C015A2 that asks for an ID to load instead.
