All Working Harry Potter and the Sorcerer's Stone Cheats - GameBoy Color

All card decks
To get all the card decks from the beginning of the game, defeat Voldemort four times.

All spells
After successfully completing the game, use the card combination that Dumbledore gave you at the end of the game at the first battle you encounter. It will give you all spells and allow you to keep them for every future battle.

Famous Witches And Wizards Cards
There are some Famous Witches And Wizards Cards in the Forbidden Forest when you are on your detention. To get them, go up to the trees and press [A].

Mucus Ad Naseum curse
Instead of finding the Mucus Ad Naseum curse in the restricted section, there is another way to do it. Before you go into your Defense Against the Dark Arts class, make sure your MP is 80 or above. Peeves will then put a curse on you, Mucus Ad Naseum. Tell Professor Quirrel, and in the Muggle Studies classroom you will find a television. "Walk" through it and it should lead to another room. Fight the monster at the bookcase and when he is defeated, you should receive a book. Go to your items, cure yourself by using it, and (if your MP is 80 or above) you will learn Mucus Ad Naseum. Return the book to Madam Pince afterwards. Mucus Ad Naseum is a very helpful curse when battling Voldemort, Professor Quirrel, and other Bosses, such as the troll in the bathroom.

More herbs
Stand in front of a piece of grass where you get herb plants. Pick it up, go into your menu, and exit out. More herbs will appear there.

Use the "More herbs" trick and you can get more than 9 herbs. Though your Ingredient Encyclopedia says you have 9, you may have 99. To find out how many you really have, press [Start] then select "Items". Go down and find the Ingredient. It will show you the number you actually have on the right side of the screen.

Quick items from bushes
You can get items at the strange bushes very quickly. Press [A] then enter the start menu. Exit the menu and press [A] again and another item will appear.

Snape's potion ingredients
When you have to look for ingredients for Snape, if you do not go directly in his office and search the poster and search for the other potions beforehand, the game thinks you already have it and the Boomslang Skin will not be there. To get around this, go outside after finding the other two potions. If you cannot find the Boomslang Skin, go outside and search everywhere for it. You can find it in strange looking bushes, trees, grass, etc.

The Boomslang Skin is usually on the Boomslang picture in Snape's office.

For the Beetles Eyes, talk to Hagrid. He says something similar to "I've got to get me some rest since I've been spraying beetles". Go to a small bush to your left to find the first portion of Beetles Eyes. The second is on the sixth floor of Hogwarts, in the mini secret room filled with hieroglyphics. Enter the room, find it, then go back outside.

For the Snake Fangs, talk to Professor Sprout. Walk into a magical encounter, look for a snake, and fight it. Once you get at least one set of snake fangs, go to Professor Sprout and she will award you 1 House Point. You may still fight the creatures to get more House Points.

Once you are done getting the ingredients, go to Professor Snape and he will award you 5 House Points. Then, complete the rest of your lessons.

When you find a ingredient plant, get the ingredient and press [Start]. Leave the menu then get the ingredient again. You can do this as many times as desired, but you can only carry nine ingredients of each type.

Wiggenweld Potion
In Gringotts' Lobby, you can get a Wiggenweld Potion by going to the space at the left in the middle. Also, the top right seat which is empty has a Famous Witches and Wizards Card.

To get more Wiggenweld Potions, when you are getting rid of your Curse of the Bogies, go see Madam Pomfrey. She will give you a Wiggenweld Potion to take. If you do not need it, try to save it for later. Another method is go in the doors to the right of and behind Madam Pomfrey. Select some objects and you will find potions in both rooms.

Cheaper spell
If you have the card combination "Scholarship" completed, cast it during a Boss battle to have all your spells costing half of the MPs (magic points) normally required. For example, Flippendo Duo normally costs 4 MP, but after casting Scholarship, it costs 2MP.

Easy house points
Before going to Hagrid's hut (when Harry found out about Norbert), go to the place where you have Flying lessons after getting all the card combinations from the Card Collectors Club. Then, talk to Madam Hooch and she will tell you to chase an owl. After catching it, you will be given 10 house points and a card combination. This can be done repeatedly, as long as the card combination are collected first.

Lose all of your House Points
When you get to the part where you need to find the trophy room to duel Malphoy, go to the fourth floor. Note: Sometimes she is on the third, fourth, or fifth floor randomly. There will be an old lady standing watch. Talk to her twice. The second time she takes away one House Point. She keeps taking away one House Point every time you talk to her.

Easy level up
Go to the hospital wing. If you are injured, talk to Madam Pomfrey. She will heal you completely. Then, go to one of the rooms beside or above Madam Pomfrey. Fight as many people as desired. When you get hurt badly, return to Madam Pomfrey to get healed. Repeat this as many times as desired.

On the sixth floor, go to Filch's office. Go to one of the chests and press [A]. Your presents will be there, but no matter what, you will lose 1 house point.

Cauldrons
While at Diagon Alley and buying school supplies, you may consider buying both cauldrons in the Cauldron Shop. More potions can be made when you have both of them. If you only have enough money for one, the collapsible cauldron is used for Wiggenweld Potions. It is a good one to have.

Bonus games
During Charms, do not stop when your feather is at the top. You will have to start all over again until you have won the entire game, not just one level. For the games when you use your broomstick, keep pressing [Right]. It makes you go faster, even if it makes you bump into objects at times. One exception is when catching the golden key. Do not try to avoid other keys; just keep pressing [Up] and when you get to the top, you may have to move around a bit. However, you will get there if you keep pressing [Up].

Duel with Draco Malphoy
When you have entered the trophy room, go straight to your left. Keep going until you find a big door. Once there, Filch will have entered the room and Mrs. Norris will be looking for you. Go through the door and you will be in another room. Then, search for another exit. You will have avoided Filch with losing any house points.
