Miscellaneous tidbits that are interesting enough to point out here.
Notes

Unused Text

Hmmm...
To do:
Find and add the original unused Japanese text.
Japanese English Translation
179: Looks like a dagger.
180: Picked up a dagger.
180: A dagger shone faintly.
307: Picked up a dagger.

As the green dagger was removed (see below), all the related text goes unused.

Japanese English Translation
270: Something grabbed my arm!

A single line that never shows up.

Japanese English Translation
412: I'm trapped...
413: This game of tag is over!

The last line is used in the PlayStation port when Ms. Mary's grabbing Jennifer's foot on a ladder.

Unused Graphics

HUD Elements

Clock Tower Jennifer Portrait.png
There's one unused portrait of a rather distressed Jennifer. The background color is fully capable of changing depending on Jennifer's life, like all others. It can be brought back with Pro Action Replay (PAR) code 7FCA4709. This portrait appears in the PlayStation port if Jennifer drinks from the cupboard in the kitchen and the drink knocks her out.

ClockTower SNES UnusedCursors.png
Two unused cursor sprites are loaded into VRAM, along with the regular cursor and items. The size of the first one makes it similar to the item selection cursor for the inventory in the PC version. The other one looks like something an in-game editor would use during development. The player palette was used for these images, as the normal cursor palette wasn't suitable.

Clock Tower Dagger.png
This green dagger can't be found anywhere in the mansion, and it was part of a removed puzzle (read below). Can be brought back with Pro Action Replay (PAR) code 7E132306, but does not interact with anything. When equipped, it's named "青銅の短剣" (bronze dagger).

ClockTower SNES UnusedKey.PNG
This unused key sprite is only found in the SNES version. Since the item tiles and item IDs are in the same order, one can assume that this is the "Ceremony Key", which comes after the "Copper Key" in the list. The four keys that normally don't show up in the inventory can all be placed there by hacking. Doing that won't show any valid sprites, though.

ClockTower SNES ElevatorDown.PNG
As the elevator only goes up, this tile is never seen.

Characters

ClockTower SNES Jen0018.gif
Jennifer Unused Graphics
Many animations were replaced or just never implemented.
ClockTower SNES Bobby0542.gif
Bobby Unused Graphics
Mostly animations that would let him follow you everywhere.

ClockTower SNES FriendsUnused.PNG

Each one of Jennifer's friends has an unused front-facing sprite.

ClockTower SNES MaryUnused1.gif ClockTower SNES MaryUnused2.gif ClockTower SNES MaryUnused3.gif ClockTower SNES MaryUnused4.png

Mary has some unused animations in which her hands are raised. There is also an idle animation of her in the black robe. She's already walking when you see her like this in-game.

Room Objects

ClockTower SNES UnusedMirror Animated.gif ClockTower SNES MirrorReflect1.gif ClockTower SNES MirrorReflect2.gif
The mirror in the first bedroom has a shattering animation that goes unused in the SNES version of the game. It is fully implemented in later ports. In addition to this, there are some unused reflection animations as well.

ClockTower SNES Can3.gif
An animation of the insecticide can suddenly tipping over.

ClockTower SNES Can4.gif
Looks like Jennifer could miss Bobby when she's throwing the can against him. Would probably be seen if the panic button had actually been put to use in that scenario.

ClockTower SNES Trophy Animated.gif
This trophy has an unused howling animation. A matching sound will occasionally play in the trophy room but the animation itself is never executed. In the PlayStation port, this head is part of the background just like the others around it, meaning it's no longer supposed to move at all.

ClockTower SNES BrainJar Animated.gif
This jar, found in the same room, is meant to be animated but will instead remain static in this version of the game. The animation should play when you hear the bubbling sound effect.

ClockTower SNES ShiningDagger Animated.gif

The green dagger, as it would appear in the room. It doesn't actually loop like in the PlayStation version, instead transitioning into a blank animation to hide it. This matches the text saying "A dagger shone faintly.", rather than "It's a glimmering dagger.", used in the PlayStation version. The object itself is already in the room and you can view its animation by heading to the crate and setting RAM address 7E1A25 to 21 (preferably with the lights off).

ClockTower SNES TrophyBox.png
A sprite version of the crate found in the trophy room. Somewhere along the way, it became part of the background instead.

ClockTower SNES DollUnused.PNG
This doll was apparently supposed to fly into the back of the room and then return. The left part shows an unused animation where the first four sprites are unique. The back-facing sprites to the right weren't added into any of the game's animations.

ClockTower SNES DollCharge.gif
There's also an animation for when the doll is about to attack. It does get used in the PlayStation version.

ClockTower SNES ParrotNoAnim.PNG
The parrot has four sprites facing away from the camera that aren't used in any of its animations.

ClockTower SNES ParrotUnused1000.gif ClockTower SNES ParrotUnused1001.gif ClockTower SNES ParrotUnused1008.gif ClockTower SNES ParrotUnused1010.gif
In addition to this, it has five unused animations, of which two are exact duplicates. It's clear that some of the bird's actions aren't fully implemented as it's never animated while inside the cage, even when it's helping Bobby find the player.

ClockTower SNES CrowUnused1.gif ClockTower SNES CrowUnused6.gif ClockTower SNES CrowUnused2.gif ClockTower SNES CrowUnused3.gif ClockTower SNES CrowUnused4.gif ClockTower SNES CrowUnused5.gif
The first two animations seen here are early drafts of the crows' attack on Bobby in the slaughter room. The rest are unused variations of when they have landed on their target, using different sprite and mirroring options.

ClockTower SNES AnimalCages Animated.gif
The rat and crow cages were supposed to be animated when being opened by the player, but these animations never get used.

ClockTower SNES PhoneRmCloset.PNG ClockTower SNES PhoneRmClosetOpen.gif ClockTower SNES PhoneRmClosetHole.gif
The closet in the phone room has some unused animations. In addition to showing the black robe (see further below), it would also act as a hiding place. All the needed animations were not completed (like the door closing again), so only the fully closed door sprite is ever used in-game.

ClockTower SNES ClosetJen1.gif ClockTower SNES ClosetJen2.gif ClockTower SNES ClosetBobby.gif
These are mockups of what some of the animations look like together with those of Jennifer and Bobby.

ClockTower SNES PhoneRmPicture.PNG
This painting was found among the sprites that belong in the phone room. Luckily, its unique palette is still included in the room's data.

ClockTower SNES CupUnused.gif
Also in the phone room, this cup has an unused animation where it falls off the table.

ClockTower SNES BobbyShed.png ClockTower SNES ShedBoxOut.gif
This animation is actually used when Jennifer climbs out of the box after hiding from Bobby, but this is not normally possible since you can't enter the shed while being chased. You can use this Pro Action Replay (PAR) code to bypass said limitation: 80994C82. When Bobby is looking around the room, he'll suddenly turn around and hurry outside. If the box is entered too late, however, Bobby will keep walking back and forth, forcing the player to restart the game. So sealing this place off was most likely a quick fix for this issue.

ClockTower SNES PlankAltAtk.gif
This is a slightly different version of the plank attack animation normally seen inside the shed. Compared to the used one, it has one more frame and it uses different sprites starting at the 6th frame.

ClockTower SNES BushUnused.gif
One of the bushes in the courtyard could have used this animation for some sort of spooky event.

ClockTower SNES MusicCurtUnused1.png ClockTower SNES MusicCurtUnused2.gif
The music room's curtain has two closing animations with unique sprites. The used animations just show the opening sprites in reverse order instead.

ClockTower SNES DanAltSplash.gif
An alternative splashing animation for when Jennifer is climbing out of the cave water. The only differences are some slight timing changes on the last few frames.

Used Unused
ClockTower SNES MuralShelf.PNG ClockTower SNES MuralShelfUnused.PNG

The shelf in the middle of the mural room looks the same as the one in the library, except it has its own palette. There is a slightly different version made for the mural room that doesn't get used. The upper part has been redrawn and it lacks a shadow and as such wouldn't match the animation where it tips over, which is probably why they went with the other sprite instead.

ClockTower SNES CerVaseUnused.PNG
The vase and flower in the ceremony room once consisted of these two separate sprites. They have since been replaced by a single sprite (using the same tiles) instead. The room still loads two sprite objects at the same spot but the second one doesn't display anything.

ClockTower SNES DoorsUnused.PNG
The doors' opening animations don't include their closed state and since most door sprites won't appear in the room until the animation starts, these sprites are never seen.

Cut Animation Frames

ClockTower SNES StorBoxUnused.PNG
This box in the storage room is never fully opened, so these sprites go unused. Some other sprites also have this sort of garbage on the last animation frame, but in this case, it would be covered by the shelf that's next to it. The garbage here happens to be copied from the early Laura sprite seen below.

ClockTower SNES StorCanUnused.PNG
This should be the frame where the contents of this can start leaking out, but it was left out of all animations.

ClockTower SNES HoleUnused.PNG
This one would be in the middle of the wall's crumbling animation, but the animation probably looks better without it.

ClockTower SNES DollCutFrame.PNG
This sprite was excluded from the doll's floating animation.

ClockTower SNES SwitchesUnused.PNG
These two sprites are skipped in the animation where you flip the switches, leaving out the halfway down state for both of them.

Sprites with Unknown Palettes

The palettes of these sprites may no longer be included in their respective room sets, so they will be shown here using a simple grayscale palette instead.

ClockTower SNES BedroomLamp.PNG
A lamp that should have been in the first bedroom.

Unused Used
ClockTower SNES ShowerVictimUnused.PNG ClockTower SNES ShowerLaura.PNG

One of the sprites for the first bathroom looks like an early version of Laura hanging in the shower.

ClockTower SNES ShowerHead.PNG
There's also a shower head sprite that's not used in the final game.

ClockTower SNES Mouse.PNG
A rat. It's not part of the trophy or slaughter room sets, so its intended location is hard to tell with certainty. Judging from the animation further down, however, it would seem to fit in the slaughter room if the cage animations had been used.

ClockTower SNES PhoneClothes.PNG
If the black robe hasn't been picked up elsewhere, you can get it from the phone room. This sprite should have been visible when Jennifer opens the closet but unfortunately all of those animations are unused and so the events are conveyed through text only instead.

ClockTower SNES UnusedShelves.PNG
These shelves appear right before the mural room set in the ROM and even has copies of that room's tiles baked into one of the sprites. Looks to be leftovers from earlier in development. The left one is a bit too large, as it will cause sprite flickering when displayed in-game.

ClockTower SNES MusicPlaceholder.PNG
This sprite belongs to the music room, but is obviously just a placeholder.

Covered Graphics

Clock Tower Dan Bed.png
While not really unused, Dan Barrows fully covers this huge pillow/nest/bed thing which — contrary to most of the game's graphics interacting with sprites — is actually fully present.

Clock Tower No Rocks.png
The dead-end hallways have another window behind the pile of rocks and not much else.

Tileset Details

ClockTower SNES BedroomTiles.png

At the end of the background tiles for the West Bedroom, there's what looks like a scratchpad area where the left bed was worked on. It's different from the right bed (the one near the lights here, that is flipped in-game), mostly around the legs. In the end, a sprite was used for the left bed instead, gaining a row of some brighter pixels.

Unused Animations with Placeholder Sprites

A whole bunch of interesting animations have been stripped of their original sprites, most likey due to space constraints. Almost all of them have been restored in later versions of the game, though often still unused. A counter has been added here to distinguish frames where needed.

ClockTower SNES Curtains3.gif ClockTower PSX Curtains3.gif
ClockTower SNES Curtains4.gif ClockTower PSX Curtains4.gif

The living room was apparently meant to have an extra hiding place behind the curtains. These animations exist in all versions of the game but are never used.

The cabinet in the same room was supposed to be openable, but here's no way to even click on it in the final game.

ClockTower SNES Clown10.gif ClockTower PSX Clown10.gif
ClockTower SNES Clown11.gif ClockTower PSX Clown11.gif

The clown doll would have been an alternative enemy in the child's bedroom, but it had to wait for the PlayStation port before getting up on its feet, having only an idle sprite used this time around.

Some of the static objects were actually meant to be used as weapons, with success depending on the use of the panic button.

SNES PlayStation
ClockTower SNES CaveStal2.gif ClockTower PSX CaveStal2.gif
ClockTower SNES CaveStal1.gif ClockTower PSX CaveStal1.gif

There would have been stalactites falling outside the elevator when it starts up and everything is shaking. If the sprites weren't removed, that is. The reason they seem to disappear early when falling in the SNES animation is because the 8-bit Y position wraps around to a negative value. This is avoided in the PlayStation version where the animation positions are 16-bit instead.

Unused Used
ClockTower SNES A999.gif ClockTower SNES Scissors203.gif

There's only one sequence in the game where Bobby and his scissors are unlinked (no longer snapping to the same position). The right animation is from the scissors set, while the left one has its own set near some other animations meant for the last part of the game. It's similar to the PC and PlayStation versions where a special image of the scissors is used when they are thrown, rather than a normal animation. In this case however, the animation from the scissors set works just fine.

ClockTower SNES Mouse1.gif ClockTower SNES Mouse2.gif
The two animations of the rat. They only exist in the SNES version.

ClockTower SNES DreamcatcherAnim1.gif ClockTower SNES DreamcatcherAnim2.gif
The dreamcatcher in the child's bedroom seems to have some scrapped animations.

ClockTower SNES DoorPart1.gif ClockTower SNES DoorPart2.gif ClockTower SNES DoorPart3.gif
This one is quite a mystery. No telling where it would belong.

Oddities

ClockTower SNES ShedObject.PNG

This object is placed inside the shed but you can't do anything with it. It's gone in the newer versions of the game.

The Cut Room

One of the rooms whose placement is randomized at the start of the game is never accessible. The door to this room is not even selectable, but the PlayStation version does add a new bedroom to fill this slot. As stated by the developers, much of the mansion was cut due to the limited number of people working on the game.[1] In fact, the room list has zeroed out pointers for a total of 12 lost rooms.

East bedroom (SNES) West bedroom (PlayStation)
ClockTower SNES EastBedroom.png ClockTower PSX WestBedroom.png

Missing Zombie Sequence

Sometimes, Jennifer might find a corpse inside a closet in the Trophy Room. There are two more pictures that go unused, showing the corpse coming back to life. In the PlayStation and WonderSwan versions, this zombie was put back in as a new enemy that chases you around until you put her to rest with the also-originally-unused green dagger, and thus obtaining the cage key off the body instead of finding it laying around.

On a side note, the "A dagger shone faintly." text shows that the dagger's location was fully conceived as it will later appear in the ports, as you can only find it once you turn off the light in a room and see it shining. However, while there are traces of things like the possessed clown doll still lingering in this version, the animations of the zombie moving around are nowhere to be found. Also, while the tiles for the bright eyes are present, there aren't actually any tilemaps that use them.

In this version of the game, you can't view the close-up image of the corpse until you've re-entered the room after seeing the jar fall down. This is because the game decompresses the close-up graphics for either the jar or the corpse when the room is entered. The jar close-up only needs to be shown once, so all later visits will load the corpse graphics.

Interactive Machine Room

If you use the Pro Action Replay (PAR) code 7FCF3D2E and go into any room (preferably a small one), you can get into the clock tower's machine room and walk around freely.

You can climb between the two areas (although Jennifer will be climbing beside the ladder when she enters the top area on the way up). The elevator acts like a wall, but you can get past it by running into it.

Since the ending plays mostly automatically, there is nothing to click on and you can't exit through the opening to the left.

Hotspots

Unused Hotspot Type

The hotspots you click on will set a walking goal for the player and a script to start. One setting will have the hotspot specify those right away, while the other will provide a goal and script for both the sides it can be approached from. There is also a third setting that is never used anywhere. It specifies a goal and an index for a table of script addresses at ROM address 80831D. The only entry in the table is 808320. The script at that address does nothing more than end immediately with the opcode 00.

This may have been used earlier in development, before being replaced by the more efficient setting that links directly to the intended script.

Inaccessible Hotspots

ClockTower SNES RubbleHiddenHotspots.png

While there seems to be nothing to do in the rubble-filled hallway in the mansion's west wing, there are actually two hotspots in that area. They are placed on the second floor, but the player must be on the lower floor to interact with them, which in turn makes that impossible. The scripts they start seem to be earlier copies of the ones used in the east wing (by the hole in the wall). The messages used for the window and the pile of junk are the same as in that area. However, Jennifer won't be climbing up to get the rock and the walking goal is further to the left.

To try these hotspots, use the Pro Action Replay (PAR) codes 7FCB8F34 and 7FCB9001 after entering this area on the second floor.

Unused Sounds

While not technically unused, the sound that the parrot makes is slightly sped-up and played with a higher pitch in-game. The original sound effect is a crystal-clear "I'll kill you."

Hidden Screens

Running the game on a PAL system or connecting either a Super NES Mouse or Multitap will make these screens appear.

The Japanese text tells you the controller is not connected properly. Bobby's voice will be heard, borrowed from the elevator sequence.

Debug Menu

This is text for a debug menu found in the ROM, copied onto the region error screen. There is no code that references the text of the first image, but much of the code for the second one is still intact. See the notes page for instructions on how to access the debug features.

The menu works by printing text and waiting for a value to be entered. Unfortunately, the printing routine does nothing and the one that should get a value is now hardcoded to respond with a 10 right away. Other than that, the menu works as expected.

When in debug mode, the list of options is triggered by pressing L+Y. Here's what you can choose:

Option Prints Effect
0 Goes to room $FFFF, which is invalid. The spawn position is suitable for a small room. This was likely changed around to whichever room needed quick access for testing at the moment.
1 Enables free camera movement with the D-Pad and locks the player.
2 Disables free camera movement and unlocks the player.
3 Changes the screen border to the one used for Dan's reveal, showing more of the room.
4 INPUT (0-15) Sets the brightness of the screen.
5 0 SILENT
1 NORMAL
2 ESCAPE
Sets chase music status.
6 INPUT ITEM# Adds the item you specify to the inventory.
7 Lets you set Jennifer's health.
8 INPUT SE# (X=CANCEL)
PRESS RESET
Plays the sound effect you specify. Seems to hang each time.
9 Displays the dialogue message with the ID you enter.
10 Takes you to the blue hallway where you meet Mary.
11 Takes you to the lower part of the machine room.
12 Takes you to the phone room. Mary being in there is still random.
13 Plays the specified music track.
14 Lets you enter a value that can mute specific audio channels.
15 Takes you to the upper part of the machine room, entered from the right side. The room is called ED6 here but CTT in the PC and PlayStation versions.
16 Takes you to the inside of the elevator.
17 Clears the save file, leaving only the string "HUMAN CORP" at the top.
18 Takes you to the caves.

Jennifer's health would be displayed after "STRENGTH = " and the last row says that pressing X would cancel the number entering process.

Pressing SELECT in debug mode attempts to print the following:

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

%WD and %WH would be replaced with the following values in decimal and hexadecimal form: cursor room position, player room position and camera room position.
