To do:
  • Find a way to decode ".geo" files.
  • Developer commentary I found here.
  • Unused debug and cheat stuff in Start.DOL [GameCube] and default.xbe [Xbox]
    • Screenshot system
    • Sound test (SNDSTRM_modifyhold)
    • "Debug Screen"
    • Map Debug
    • Much more (I don't understand the purpose of certain instructions)

The GameCube and Xbox version of Harry Potter and the Chamber of Secrets is a prime example of the multi-platform weirdness that plagued licensed games in the early 2000s: this version was made by Eurocom, in collaboration with EA UK formerly known as Bullfrog Productions. The original contract tasked the studios to adapt the first book of Harry Potter into a game until delays caused the contract to change and instead involve adapting the second book, which lead to having to cut lots of work such as the mountain troll in the Girls' Bathroom, Firenze the centaur, all the way to Voldemort himself.

Eurocom initially created something new that didn't resemble the expectations of EA Games, Warner Bros. nor J.K. Rowling, making this game more original, more stylized, and moving away from the movie and many things created by Eurocom were refused by the publisher, including Hogwarts paintings paying homage to the developers who went through months of suffering, internal pressure and families amputated from their fathers.

Deleted Files


The execution roots of the game refers to two files named "harryskin.geo" and "harryskin.gdt" which is never executed and no longer exists in the game or any version of it. At one point the game could have originally run the Harry model on this file, and run these animations on the used file "harry.geo" as it is with the prefects with "MalePrefect.geo" and "MalePrefectSkin.geo".

Unused Levels

Burrow 2

The gamecube and Xbox version has left in their file, a much older version of the burrow. The much difference is in but the format is a little older and cannot be load by the game, the file isn't even implemented in the game code itself.

Early Final
HPCOS Burrow2.png HPCOS BURROW2 final.png
Windows and walls inside the house


  • The house is modelised in his entierly which is not the case in the final version. The house is cut in four pieces, depending on where harry is, one side of the house will unload to save resources.
  • The Ford Anglia model is include in the scene. The final version of the burrow load the car from a separted file.
  • The skybox is different and can be seen on early pre-released screenshot of the game.
  • The sun is an ankward yellow circle as a placeolder.
  • The house has a window and wall inside it.
  • The ground texturing is more simple
  • Minor map modelisation difference
  • The map contain some extra furniture that does not exist in the final version.

The Ollivender Shop

The famous wand shop is somehow still in the Xbox game files under the name "cutscene.geo", even if it is a full level. When the project for EA UK and Eurocom was to make an adaptation of the first book, you would have started out at the Ollivander's shop. It is not clear what you were supposed to do, though various early models of Harry and Filch can be found.

Unused Dungeon

This dungeon is called PreLibry, and from its appearance, it might be an early version of the Restricted Section...

This level is really unfinished: there is no exit and it has a lot of bugs like the doors being invisible (which is fixed when a Prefect sees you), the spells don't work (even those cast by Prefects), and when you restart the level all the sounds of the game except the music and Harry's voice will be disabled. There are LOTS of chests and jars, but they are all empty. There is no overhead camera as in the final version, so the camera is always stuck between two walls.

The Prefects have slightly different behavior, more reminiscent of the PlayStation 2 version, but their spells don't work. They do chase you as in the PS2 version, however, and them catching up forces retrying the level.

When you arrive in the big room, there is a blocked door; you were probably meant to cast Flipendo on a button. However, it's possible to get into the room after the blocked door by going through the walls via bad collision detection. You will first have to go through a secret corridor, and at the end of it there is a door that was probably implemented without a corresponding room or door to it; by crossing it, the player will find himself inside the wall and be able to go to the last room.

At the end of the room there is a portrait; thanks to the Free Camera hack, we can see that there is a hole to get out from, but the painting was not programmed to open, so this level has no exit.

Unused Whomping Willow Area

This level seems to be an early version of the Gytrash area of the final version... It introduces an original and unused system of minecarts that can be pushed to reach a high place, it works like the final game's crate. However, these minecarts don't work properly, as they don't move forward and can be directed in wrong directions.

The Gytrash arena features eight ones to defeat unlike the final map where there are only three. Then, further on, the player drops a minecart through Flipendo and was meant to push the minecart to get to the high ground. Once up there, the player gets a chest with a Chocolate Frog and a Pumpkin Pasty. Hedwig has to be called and the minecraft moved to get to the land behind the perch. There is a minecart that needs to be oriented by the Puffapod so that it can be pushed down, but sometimes the minecart is oriented in the wrong direction. The player must then find, on the land next to it, an Owl Treat for Hedwig to unlock the exit that leads to the boss of the level.

Note that the level does not have any ambient sounds apart from the music and the thunder.

This level is an inventory map but it is not even used in-game, making it doubly unused. HPCOS gytrash map.png

Test Maps

The game contains 14 test maps, they were created by the different programmers of the game and left their initial on the map. Each map seems to be an early version of the Entrance Hall with the textures being made of "clay", all with a different brightness and all contain different content inside. Some of them have their own specificity, such as some lacking ground collision and others like test_AW which has the music of the Girls' Bathroom and can even run the cutscene of night 3, however it will crash the game if the level is entered on night 5. The last level test_SJ, (the asylum) will crash the game when loaded probably due to the presence of the flame thrower statues in the Experliarmus map.

The Pink Room

In the game's files, there is a test level named "PinkRoom.geo". It can be loaded by replacing files.

This level is quite simple: there are various objects that don't always work. The most interesting thing about these objects is that there are unused ones, like a rotating trash can that gives infinite beans. But most notable is Dobby's head, which is animated (the Dobby model is actually used in the PS1 version of the game; the images used in the book are the models of the GameCube/Xbox versions). Harry seems to have an interaction in front of him. There are also scales that don't look like the ones that can be seen in the game.


Also known as "Animation Viewer", this is a large, gray, empty room that the developers used to visualize almost every character's 3D model in-game. You can visualize the animation of Tom the Barman and a Particle effect and that seem to be it...

The footage here is from the Xbox version, the script doesn't work on GameCube.

With the second controller:

  • Right Trigger hides the text
  • Left displays a character model
  • D-Pad down changes the character
  • A plays or stops animations
  • X "stops running scripts".

...The script itself doesn't even work well.


A file named Infirmary.geo is present in the game, so it is likely that the Hospital Wing was supposed to be a room in the game. However, the file is empty, with the only thing marked INFIRMARY.A-1, so it is likely that this room was never started. It was probably deleted because the sequence of Harry's accident and his subsequent stay in the infirmary in the original story is omitted here.

Quidditch Common Room?

There is an unused loading screen in the game named QuiddCommonLS.geo. The image of the loading screen shows the image of the Griffindor Common Room, which indicates that the map was probably never made. The name of this file suggests that it is probably a Quidditch locker room or something else.

DADA Fumos

An empty map called Fumos, it is possible that originally, Harry should have learned to cast the Smokescreen spell. It is also possible that this is a second Defend Against the Dark Arts (DADA) spell challenge which was scrapped as evidenced by this element of the DADA map.

Unused or Unseen Map Geometry

PS2 Confiscated Items Room

The confiscated items room of the PS2 version is present in this version, but is completely empty, and the door cannot be opened. The room mesh itself is identical to the PS2 version's.

HP COS GHSE69-75.png

The PS2 door

The PS2 version has a door, at the Hogwarts Grounds, which leads to a balcony. This door is absent here but can be seen from the Herbology Greenshouse.

From the Herbology From the Hogwarts Grounds
HPCOS the door.png HPCOS theoddr1.png

Defense Against the Dark Arts

In the Defense Against the Dark Arts classroom, behind a portrait, there is a hole where Harry might've been meant to pass through, but the painting is never opened. It is likely that these are remnants of a deleted challenge, or the old location of the portrait for entry into the first challenge.

Note that in the next game, the hole is no longer there, but there is a poorly textured square at that location.

HP COS GHSE69-56.png


In the corridor of the library, behind the portrait that came out of the reserve, there is a piece of the floor, indicating that a double door must have originally been there instead of the portrait.

HP COS GHSE69-67.png

The Burrow

After beating the washing machine, before the player goes into the garden, off the screen is Fred & George where their feet are slightly below the ground.

HPCOS GHSE69-77.png

Library Annexe Area 2

The second area of the Library Annexe, which the player visits during their second night at Hogwarts, seems to also contain a daytime version and loads simultaneously with the first area of the Annexe. No Prefects are found on patrol during the day in both sections. During any other night than night 2, both parts of the Annexe remain under supervision of the Prefects, even if the door is locked and inaccessible to the player.

The room is accessible with external hacks, as seen in the embedded video:

Unused Option

Chests Objects ID

The game's chests can contain a number of different items, some of which are never found in normal play. Chests can be configured to change the ID of the objects contained in them.

id Object Model
00 00 Nothing Nothing

10 00 Dungbomb DungBomb Opening the chest will make the game skip some frames to load the dungbomb model, collecting them will not affect your inventory, as you cannot use dungbombs in the game anyway.

Potion Vial

The 3 potion vials can be assigned to X, Y and B via memory modification. It is normally impossible to do this and it would have no effect under any circumstances, but at some point in development you could have drunk the Wiggenweld potion by yourself rather than having it done automatically.

HPCOS Potion.png

Hogward's Flags

Flags on top of each tower of the Hogward Castle are red, but it can be configured in memory to change the texture to yellow, blue, green or black.

These colors are used in the Quiddictch Pitch.

Yellow Blue HPCOS Flag green.png

HPCOS Flag black.png

Bloody Baron

The Bloody Baron has an unused option that makes him appear and disappear at the rate of the Hogwarts clock. (I swear, we don't know any more than you do!)

Quidditch Class numeric timer

Time Left %d:%d

The timer of Madam Hooch's exam is represented by a clock graphic, however the game code has a timer in minutes and seconds that would have been displayed.

Incendio in Duel

Although the Standard Book of Spells (Grade 2) states that the Incendio spell may be used for Duelling, the player is never given the chance to do so. Gargoyles can only be defeated by reflecting their attacks, and the duels with Malfoy and Goyle take place during Day 2 and Night 2 - two days before the Incendio challenge. However, if you load one of the two dueling levels after the challenge using hacks, or use cheats to gain all the spells before one of them takes place, you are actually able to fight Malfoy and Goyle using the Incendio charm. They will reflect the spell back at the player with Expelliarmus just as they would with Flipendo. When an opponent is properly hit with Incendio, it also deducts a point from their total. Other spells gained after the duels, such as Alohomora and Avifors, won't do anything when used.

An unmentioned feature of the Expelliarmus spell is whenever the player reflects attacks back at enemies, the analog stick can be used to steer the spell in any desired direction before letting go of the casting button.

Unused Duelist

There is a file named DuelPupil; it is a duel opponent (like Malfoy or Goyle), the data of this file indicates that it is more than one student of Hogwarts (as in, the file contains all the alternative forms of the students). But when it is loaded into the game, it takes the form of Harry for some reason. This may have something to do with the unused dialogue lines in the library reserve.

Unused Object

Unknown Potion


As with "UNKNOWN SPELL", this line can be found among the names of spells in the inventory. It's probably a placeholder from development, or a fallback in case the game does not recognize a potion. However, in the final game, the Wiggenweld potion is the only potion in the game.

Unused Texture(s)

Debug Font

HPCOS Acorn font.png

Text font use by any debug feature of the game. The texture is call "acorn_font" because it is the text font from the RISC OS by Acorn Computers

Dumbledore's Office Maps

Two map textures for Dumbledore's office exist, but go unused since the office is impossible to enter by normal means.

HP COS GHSE69-88.png HP COS GHSE69-87.png

Quidditch Stadium Map

The Quidditch Stadium also has a map in the inventory that goes unused, as the player only visits the stadium while on a broom, and the inventory is inaccessible during a match or training.

HP COS GHSE69-89.png


Found in Test_DP, it seems to be a very compressed poster of Ron Weasley that is just called "ron". It is unknow what was the point of this picture. HP GOS flying dude.png

Tom The Barman

Tom the Leaky Cauldron bartender has a temporary texture made up of some colour palette is found with Tom's model but is never used. It must have been used in the development process before his final texture was finalised.

HPCOS tom.png


The game has a fabulous dark blue tapestry called "DemoTapestry" which is technically present and loaded in the Pink Room but never appears. There is Diffindo-ripped version of this tapestry too.

HPCOS BAN DemoTapestry CS.png

Early inventory screenshot

Found in the unused Quidditch Screen. A screenshot of the inventory, Quidditch results can be found, the inventory was originally much lighter and coloured with gold. An identical design can be found in screenshots of the PS2 version.

Hpcos inventory.png

Early Washing Machin Icon

The final icon of the washing machine has a different outline and a different "pose".

HPcos Washingmachine2.png

Early title Screen Graphics

The unused Quidditch Screen, as seen more below, allowed early development graphics to survive. The Burrow and The Expelliarmus Challenge were playable levels at E3 2002; it is possible they were made for a playable demo.

The golden line is a loading bar, it seem to be the same as that in the PS2 version.

Quidditch HUD

The HUD would initially have shown Harry's, the Snitch's and the opposing Seeker's positions.

This one is name "QD_HUD_boostfull", the hud would have an visual trigger for when the broom boost is available.

Unused Cutscenes


Chocolate Frog

The cutscene takes place in the barnyard, on the corpse of this chocolate toad. Harry would have originally gotten the Wizard Cards from Chocolate Frogs as he understood it, rather than from the chests. The Card don't spin like this in the game and it don't fully follow Harry's movement, because his pickup animation was different at the time. The cutscene with proper animation can be seen at E3 2002. It uses one of the unused lines, too.

Washing Machine

Most of the cutscenes for the Burrow are executed in the file CS_BU.geo, the only exception being the first cutscene CS_NEW01_01.geo, after breaking the glass jar CS_LVBUR_03e.GDT and the last cutscene CS_LVBUR_01.geo. There are however 7 alternative versions of the cutscenes executed in CS_BU.geo: the reason is probably that during development these cutscenes were executed separately, like the glass jar cutscene CS_LVBUR_03e.GDT as well as all the cutscenes of the game, but then most of the cutscenes were grouped in one file (but the old versions were never deleted, making them unused)...

The most remarkable change are the two extra dialogues of Ron and Harry that are not used in the final game. The camera angles are different and the movements are more abrupt. The sound effects of the washing machine are different and placed at a slightly different time.


A version of the second cutscene where nothing happens with different camera shots.

The Gnome in the garden

The movement and camera angles in this scene are very different from the final version and the first shot of this cutscene does not exist in the final cutscene, it starts directly for the shot on Harry. Fred, instead of saying "be my guest" says "you'll never beat my record", then goes over the line of Goerge and it is probable that at the time this cutscene was made, the line was different or had to correspond to something else.

Flourish and Blotts

CS_FB is a file that is loaded when entering Flourish and Blotts, though it never went used. This one contains 7 cutscenes from very early development... Moderately interesting to see except the first one named "CS_FB_harryenters". Harry is roughly animated and he enters the shop and sees a journalist using an old version of the unused Purple Wizard and an invisible Lockhart (invisible because the game could not load his model for some reason) and this is followed by two completely unused dialogues and then a long silence.

It is likely that he would have spoken to Harry, before the latter left with his book collection as shown in the old subtitle.


There are several alternative versions of the cutscene where Harry returns from the Experliarmus challenge. They are curiously much shorter, stopping at the moment when Lockart gives out the points. The only difference between these versions is that Lockart gives out different numbers of points between 5 and 60, in the final version he only gives out 40. And the sound of the painting is missing.

Gambol and Japes

Two cutscenes exist for Gambol and Japes under the name CS_LVGAJ_01e.geo and CS_LVGAJ_02e.geo but it is only a copy of the Flourish and Blotts unused cutscene CS_LVFAB_01e.geo.


One cutscene exist at the Mulpeppers under the name CS_LVMUL_01e.geo but it is only a copy of the Flourish and Blotts unused cutscene CS_LVFAB_01e.geo.

Unused Text

Developer text

Who have I missed? I must have missed someone

Found in the texts of the game credits: we hope for their sake they didn't forget anyone!


Potion Ingredient - Flobberworm Mucus 
Potion Ingredient - Doxy Egg 
Potion Ingredient - Salamander Skin 
Potion Ingredient - Billywig Sting 
Potion Ingredient - Firecrab Shell 
Potion Ingredient - Mandrake Root

The potion classes with Snape should have been present in the game as also implied by Ron in Diagon Alley.

Herbology Class

in the "langtext" file, the Herbology greenhouse was once referred to as a classroom, a class criminally absent from the game despite the original book or the movie scene, the 3D model of the teacher still exists as seen above.

Hagrid's Hut (Locked)

The text indicating where Harry is contains this text for Hagrid's hut, but the door has no interaction, unlike in the PS2 version.

Main Gates (Locked)

There is no door named as such.

Gringotts Bank (Closed)

It is not possible to enter Gringotts through Diagon Alley even though the bank itself is attached to the location. During development, the Gringotts bank was accessible from there, and even with the mention of being "closed" the door has no interaction implemented on the scene, so this text is never seen.

Exit to Diagon Alley

There is no place to "exit" Diagon Alley in a literal way

Exit to Knockturn Alley

This place is not represented in the final game unlike the movie.


Harry Potter lived at number four Privet Drive with his horrid Uncle and Aunt and their vile son, Dudley. Harry was often locked in his room and even though he was actually a wizard, he couldn't magic himself to freedom. One evening, a house-elf called Dobby appeared ... Dobby warned Harry not to return to Hogwarts School of Witchcraft and Wizardry ... Harry Potter must not return to Hogwarts! There is a plot to make most terrible things happen. if Harry oter goes back to Hogwarts, he will be in mortal danger. Dobby disappeared and shortly after, Harry's best friend, Ron Weasley, and his brothers, Fred and George, arrived in a flying Ford Anglia to rescue Harry from his prison. They flew him to their home, the Burrow, which is where , on a warm evening in late August, our story continues ...

Text for an unused introductory cutscene narrating the events of the story up until the game starts at the Burrow. The text is similar to the opening cutscenes of the PC and PS1 versions, but not identical to either. In the final versions of the sixth generation console adaptations, the game starts directly with Harry, Ron and his brothers arriving at the Burrow, with no introductory cutscene. Apart from this text, there is no data about this cutscene.

Dear Harry...

Dear Harry - Mind yourself with those Puffapods, they can explode very easily. I once threw one away and the explosion turned my wheelbarrow right around. Hagrid.

Found among advices texts... Hagrid's message could have been in the PC or PS1 version, but it's unknown in which circumstance this message could have been prompted since the first time we see the Puffapods is in the Whomping Willow's area.

Wizard Cards...?


Who knows? It is possible these were temporary strings to ensure no Wizard Card ended up using the wrong text string, when the later cards would display in the Folio Magi. This string appears 10 times.


You've lost the match against Hufflepuff.  You will need a better result to secure the Quidditch Cup.  Press   to replay this match or   to continue.
You've lost the match against Ravenclaw.  You will need a better result to secure the Quidditch Cup.  Press   to replay this match or   to continue.
You've lost the match against Slytherin.  You will need a better result to secure the Quidditch Cup.  Press   to replay this match or   to continue.

Seemingly it was once possible to replay lost games.



This sentence is repeated 14 times in the text files of the credits.

You collected a...

Lumos/Nox spell collected.
Diffindo spell collected.
Expelliarmus spell collected.
Skurge spell collected.
History Book collected.
Incendio spell collected.
Avifors spell collected.
Flipendo spell collected.
You collected a Spell.
You collected a Wizard Card!
You collected one Knut!
You collected one Galleon!
A packet of Belching Powder!

The first line in this suggests the Lumos spell was to be toggleable, as Nox is the canon incantation to disspell Lumos. However, the spell was ultimately made to dissipate after a short time, making Nox unnecessary. The latter lines here are generic-styled pickup text strings, while the PAUSED_CONTINUE string is what it is, for pausing the game.

The other strings after it are never displayed; the first is plainly obvious, no text is displayed when picking up a Wizard Card at the moment it vanishes in Harry's hand, and neither Knuts nor Galleons appear in Diagon Alley.

You collected your potion kit; you how have 1 phial to collect potions with!
You collected a phial of Wiggenweld!
A packet of Belching Powder!
You collected a Book!
You collected a Bertie Botts Bean Bag! You can now collect 10 more beans!
You cannot collect any more Beans!
You cannot collect any more Stinkpellets!
You cannot collect any more Balloons!
You collected a Bertie Botts Bean!

Much like before, these are generic strings for collecting mandatory items for Harry's second-year adventure at Hogwarts.

  • The first line regarding a potion kit suggests that Harry would keep a kit containing his set of any potions he might find, rather than just the Wiggenweld that happens to be common almost everywhere around Wizengamot.
  • The book is stored amongst the strings for Ginny's lost items, indicating that Harry would have to find that as well.
  • There are no Bertie Botts Bean Bags that increase the carrying capacity by ten in the final game.
  • Instead of the string displaying, Harry speaks upon trying to pick up more beans than he can carry. The strings for Stinkpellets and Balloons are completely unused.
  • The generic string for collecting a bean was definitely a placeholder, before the designers came up with comical reactions for picking up different flavors.

Harry's Actions

  • The former string is a non-spaced version, as the used one has the two words spaced from each other. The string can be seen in a screenshot featured in the European manual.
  • Unsneak is done in this game by moving Harry away from the wall he is sneaking on, unlike in the PS2 version where a button press can also be done. This game's successor makes it actually possible to unsneak.

Trading Wizard Cards

Test strings for card-trading sequences, stored in ALT.bin:

Do u like trading Wizard Cards?
I have Wizard Card 2, and will swap you for Wizard Card 59?
I have Wizard Card 23, and will swap you for Wizard Card 27?
I have Wizard Card 36, and will swap you for Wizard Card 84?
I have Wizard Card 61, and will swap you for Wizard Card 77?
I have Wizard Card 75, and will swap you for Wizard Card 13?
I have Wizard Card 78, and will swap you for Wizard Card 98?
I have Wizard Card 81, and will swap you for Wizard Card 43?
I have Wizard Card 94, and will swap you for Wizard Card 31?
Ok thanks harry - nice doing business with you!
Sorry Harry, I dont have any Wizardcards to swap!
Ahh yes I have that Wizard Card. Lets swap!
I'm sorry, I don't have that card available to swap!


The original, hand-written manuscript of Hogwarts: A History takes pride of place in this library and can only be viewed by special appointment.  However, students may admire its ornate cover from below.

This text is found just after Hagrid's sweet letter. The game never mentions an "appointment" to see the book that has to be stolen in the game, it is only "cover adorned" from below. This text does appear in the PlayStation 2 version, however.

Harry's First Day
Neville's Toad
The Parselmouth
Hogwarts: A History
Avifors Challenge
The Polyjuice Potion
Tom Riddle
Gryffindor vs. Slytherin
The Chamber of Secrets
The Last Day of Term

A string of text which seems tied to the days' quest lines; these strings are never executed.

Xbox Leftover


The texture of the Xbox version's buttons can be found fully functional in the game files under the name panel.geo and also under all its translations. It is possible to play with the Xbox buttons' textures by replacing the files, but the spells assigned to the X button will be visually assigned to B and the spells assigned to B will be visually assigned to A (spells can not be assigned to button A in the GameCube version).

Note that the texture of the buttons of this version are stored under the name panel_GC.geo.





The DADA and the Expeliarmus map loaded together in a model viewer, they fit together very well.
  • Just like the Avifors challenge, the Defense Against The Dark Art class and the Expeliarmus challenge was once the very same map, the reason for the separation would be because the map would be too big, it is impossible to load the DADA room in the Expelliarmus challenge and vise versa. It's the reason of the unnecessarily gigantic size of the skybox.
  • In FXmap.dbg, DDOFFICE_DOOR_OPEN and DDOFFICE_DOOR_CLOSE are listed as sounds, but the door of Dumbledore's office never opens like it does in the PS2 version of the game.
  • In FXmap.gbg, DIAGON_GRINGOTTS_DOOR_CLOSE and DIAGON_GRINGOTTS_DOOR_OPEN are listed as sounds, it seems that Gringott's Bank should have been accessible through Diagon Alley at some point in development.

Unused Screen

Language screen

HPCOS language.png The language selection screen is completely unused in the American version of the game, trying to access it will display 6 American flags, choosing any flag will have no effect. In the European version, only the English flag is shown to select the English dialogs.

Moreover the screen has a duplicate present at the first address of the title screen (that means basically that the game should have asked you for your language before the EA logo appears, this does not happen in any version).

Quidditch Win Screen

HPCOS GHSE69-121.png HPCOS GHSE69-180.png The game file has a dedicated screen of when you lose or win a game of Quidditch, it shows the screen of when you face Slytherin by default, or Gryffindor on winning. It was supposed to appear at the end of the match of Slytherin VS. Gryffindor.

Leaving this screen warps you back to the Hogwarts Grounds but curiously, if this is executed at night, Harry spawns higher above the ground...

Phrase Display "Doodah"

HP COS GHSE69-92.png HP COS GHSE69-93.png This is a Text Debug menu, it allows displaying all the text strings of the game. You just have to press the left analogical stick to change the text, the D-PAD to make them scroll and L/R to change the text bank.

The Xbox version has additional details that are technically loaded in the GameCube version but curiously not displayed.

Xbox version

Unused Sounds

Harry's scrapped monologue

This version contains a non-compiled Sound Forge file named "sfx_harry.snd", it contains some monologue that (except for the Bean) does not exist in the game, not even in the subtitles.

File where it was found Clip Subtitle Comment
Woaw, a Dung Bomb! Smells horrible, this will come in useful for clearing crowds. Dung Bombs are totally unused in the game and are unusable since they were never finished.
Bertie Botts bean flavors. These would be reused, but also re-recorded, for the 2003 Sorcerer's Stone adaptation.
Healing items, specifically the Pumpkin Pasty and Cauldron Cakes.
A balloon in a box ! Great for surprising people with.

A balloon in a box !

It is strange that it specifies "in a box", the balloons do not have a box.
A chocolate frog ! It's even got a Wizard Card !

A Chocolate frog !

In Harry Potter, Chocolate Frogs are always sold with a card, but not in this game. An unused monologue of Harry mentioning the name "Chocolate frog card" although he never calls it that and there is no Frog.
An Owl treat ! If I feed this to Hedwig when she's sitting on her perch, then something may happen !

An Owl Treat

It is in his interest that this "something" happens.
Woaw, I found a gold Galleon

A gold Galleon
Great ! A silver Sickle
A Silver Sickle
Wicked ! Some Knuts, Wizard money !
Knuts !

Galleons, Sickles and Knuts are British wizarding money in Harry Potter. Only the Sickles appear in the final game. However, according to some text placeholder and a menu, the Galleon and other money would have been collectable at the Leaky Cauldron rather than via Molly Weasley and the barrels.

This term I shall be teaching Duelling. Let me introduce you to my assistant Professor Snape. He tells me he knows a little about duelling himself and has sportingly agreed to help me with a short demonstration. Linked to the confrontation between Snape and Lockart which no longer takes place. The end of this sentence was curiously cut off during the pronunciation of "with".
I don't think so, ' time to split up the dream team I think. Mister Malfoy, come over here While the dialogue "Mister Malfoy, come over here" is used in the game, the unused dialogue files in "EaSound" reveal that the first part of the dialogue which is actually a response to a lost line of Lockart's which, according to the subtitle, says "If you'd like to partner up with Mr Weasley-' for the duel. Both lines are used in full in the PC version, but use different takes.

The old Hag

File where it was found Clip Subtitle Comment
You don't want to spend to much in Knockturn Alley, dearie. Hag's dialogue, the unused NPC, seems to have been scattered in the 3 versions of this game, 4 lines in the GameCube version, 2 in the PS2 version especially this one with the only difference being the echo effect.

Unused Map

Gringotts Bank

The bank of Gringotts is a map exclusive to the GameCube version. To unlock it you just have to connect your GBA to the system and find the required cards on the GBA version. The portrait was completely locked on the Xbox version but it is possible to access it via cheats: the room remains unchanged because the version is the version where the developers worked and also because the map was accessible via Diagon Alley during development.

Internal project Name

The game is often referenced as "Egos" or "EGS".
