Harry Potter and the Sorcerer's Stone is a turn-based RPG based on the novel (during the same time as the film adaptation has been made). You have found a Famous Witches and Wizards Card!

See also Harry Potter and the Chamber of Secrets.

To do:
The Boomslang Skin bug was apparently fixed in the Japanese and second-run European versions.

Prerelease Info
Miscellaneous tidbits that are interesting enough to point out here.
Unused Text
A lot of interesting stuff here.



Set $FFD2 to $44 to enter the CHEAT menu, which lets you warp to any map in the game (unfortunately, there are no unused ones). The button combination Up + A + B + Select held for 32 frames in the overworld would have activated this menu, but the code is skipped over. It's located at $00:$17b3.

The menu can also be accessed with GameShark code 0144D2FF. Note that the code must be disabled once inside the menu in order for it to function properly.

CHEAT Menu Sound Test

There is also a CHEAT menu containing a sound test functioning like the one in the sequel. The code for it follows the code for the regular cheat menu, with the init routine being at 01:4d5f.

Unused KnowWonder Intro


There is an unused intro screen of the developer, KnowWonder. To trigger it, set $FFD2 to $02.

Unused Griptonite Logo Easter Egg

HP1 GBC Telescope Griptonite Logo.png

There is an unused and partly drawn over logo of the developer, Griptonite Games, hidden on the starfield of the telescope. The logo is the same color as the dark blue background, so it cannot be seen; the palette has been adjusted to make it white. It seems that at some point, the stars and galaxies were moved around, making the logo partly corrupt. There doesn't appear to be a way to make the logo appear.

Unused Items

Star Chart may have been related to the Astronomy Tower quest.

Spellbook was intended to hold spells you learn throughout the game. This is supported by a line used in the game: "I'm awarding 25 house points to Gryffindor, and you'll find a new spell transcribed into your spellbook."

Parchment, Notebook, The Daily Prophet, and Hagrid's Umbrella are all unused.

Broomstick Care Kit suggests that brooms were originally going to play a much larger role in the game. Although there are four flying minigames in total, the only one that yields a broom as an item is the Flying Key minigame (Comet 260).

Harry-Potter-Sorcerer-GBC-Item-Ordinary-Broom.png Harry-Potter-Sorcerer-GBC-Item-Nimbus-2000.png Harry-Potter-Sorcerer-GBC-Item-Shooting-Star.png
The Ordinary Broom, Nimbus 2000, and the Shooting Star go unused. Ultimately, the broom shop in Diagon Alley never sells anything to Harry. The script in the room of the final dungeon with the flying key checks for the presence of the unobtainable Nimbus 2000.

Harry-Potter-Sorcerer-GBC-Item-Coal.png Harry-Potter-Sorcerer-GBC-Item-Holiday-Popper.png
Coal and Holiday Popper are unused Christmas items.

Harry-Potter-Sorcerer-GBC-Item-Luminous-Balloons.png Harry-Potter-Sorcerer-GBC-Item-Warts-Kit.png
The Luminous Balloons and the Grow Your Own Warts Kit are intended to come from the Holiday Popper. This is indicated in chapter 12 of the novel. Luminous Balloons are seen in Sorcerer's Stone and Chamber of Secrets on other consoles - they are primarily used to distract people.

Harry-Potter-Sorcerer-GBC-Item-Flying-Key.png Harry-Potter-Sorcerer-GBC-Item-Sorcerer-Stone.png
The Sorcerer's Stone is never used as an item in the game. The Flying Key is never an item in the inventory, since it is immediately used after being caught.

Harry-Potter-Sorcerer-GBC-Item-Dustpan.png Harry-Potter-Sorcerer-GBC-Item-Sickles.png Harry-Potter-Sorcerer-GBC-Item-Healing-Sparkle.png
Dustpan, Sickles and Healing Sparkle are never inventory items. Dustpan is seen as a sprite in the broom closet by the Great Hall, and Sickles & Healing Sparkle (Revive) are only seen as dialogue icons in the game.

Unused Music

This is an unused song from the game. Could have possibly been used for one of the quest completed screens.

Unused Armor Gallery Countdowns


There are four countdown variables, offset by $40 and decremented by two every frame only in the Armor Gallery. They do not appear to be used by any other code. The static holes in the ground may be related to these variables, possibly having been intended to work as spikes or similar.

Partially Unused Potions Class Script

The script for Snape during the Potions class is broken. After Harry fails to bring the necessary items once, Snape will not speak to Harry until he collects them all. However, there is code for three more consecutive failure scenarios:

Incomplete. One point deduction. You're letting down your friend Mr. Longbottom.
Too few ingredients, Potter. Back to your search.
Your friend couldn't wait and had to go to the Infirmary. Poor work, Mr. Potter. 5 points from Gryffindor. Class dismissed.

The code is buggy and jumps over these.

Moreover, the game contains an unused copy of the Snape script. It contains the same bug and is possibly an early version, as it has some further differences:

  • It checks if Harry has exactly the amount of ingredients needed. If they have more, he will be denied.
  • It doesn't take the ingredients away from Harry.
  • It only gives two house points for bringing the ingredients instead of five.
  • It doesn't show the full screen quest finished screen and warp Harry to the Dungeons.

Folio Brevis

The Folio Brevis is a book for Harry to temporarily store Famous Witches and Wizards Cards he finds in his adventures. You can then go to the Folio Magi (probably stored in the Wizard Card Collector's Club), where you can deposit and view all collected Wizard Cards. Because there is no mention of the Folio Triplicus, it's very possible that the Brevis was cut early in development. An icon for the Brevis may not exist at all.

  • The Folio Brevis had a limited number of cards it could hold.

You cannot pickup any more cards as your Folio Brevis is full!

  • Hagrid was originally intended to give Harry the Folio Magi/Triplicus in Diagon Alley. This block of text generously describes the functions of the Folio Brevis.

Before I go, you'll be wantin' these. All the students at Hogwarts are keen on Famous Witches and Wizards Cards. These Folios are where yeh store the cards. Yeh carry the Folio Brevis around with yeh, but the Folio Magi, yer main album, is too big to carry aroun'. Yours is already at Hogwarts waiting for yeh, but yeh can still look at it now. Yeh jus' can't put your cards in it yet.

Unused Penalties

Harry was intended to lose House Points for disturbing classes. This feature was most likely cut due to the lack of opportunities Harry has to gain House Points. Instead of full classes for Harry to interrupt, they are simply left empty, with magical encounters enabled. Messages from teachers taking away house points are scattered throughout the various classes Harry attends.

  • A reference to this still exists in the game; when looking for the Gryffindor password, a student on the second floor warns Harry.

Don't walk in on classes that are in session. Most of the teachers take away house points if you interrupt them.


You're interrupting a class! That's a 5 House Point penalty on Gryffindor!

Defense Against the Dark Arts

  • Harry disrupting the History of Magic and Flying classes.

You've interrupted a class in session! That's a 5 House Point Penalty!

... during the wildcat Gargoyle Strike of 1911, the wildcats were winning when...

Please enjoy the 5 House Point penalty you've earned for interrupting my class, Potter!

5 House Point penalty, Mr. Potter, for landing on my field!

Say hello to Harry, everyone. Say goodbye to 5 house points, Harry, for interrupting class.


  • Harry appears to be disturbing Professor Binns' History of Magic class.

...the 14th Century economic bubble burst following the Soap Blizzard of 1378...

Harry, you startled me! But I won't deduct extra house points, just the usual 5 for interrupting.

Always an honor to have you drop by my class. Sorry about the 5 point penalty for interrupting it.
