I intend to try and develop a set for this game; however, I'm new to both developing and computer science as a whole. I expect it will take a great deal of time to get things figured out. Also, I will probably have to play through this entire game numerous times in order to make all of the achievements. If anyone has any suggestions, feel free to share. Here is what the set will probably look like (updated on 11/27/18):

COMPLETING BESTIARY (49 points)
- For the time being, I have removed Dark Goblin and Doxy Queen from Horrible Humanoids along with Emerald Firecrab from Raging Reptiles. I cannot seem to find them within the game nor can I find any online resource that lists monster locations for this game.

If anyone has found any of these three monsters, please send me a message with their location(s), and I will add them back into the achievements.

Below is what I plan to use as this game's rich presence. I thought it fitting to display a complete sentence that conveys as much information as possible rather than a collection of figures since this game is based off a well-written novel known for its description. This will have to be revised if it turns out that "&" doesn't actually stop further text from being displayed since it wasn't working when I manually edited the rich.txt. Other than that, I am quite satisfied.

I'm planning on adding leaderboards for each of the minigames on the highest difficulty. If anyone is interested in trying them but does not wish to play through the full game, here is a save file with all the minigames unlocked. Just select Minigames from the Title Screen.
All Mini-games Save

Here is all of the relevant information about both the achievement set and the game itself that I can think to provide. Most of this is also posted on the game's page.

About the specifics of the set itself, I used Harry Potter and the Chamber of Secrets (USA, Europe) (En,Fr,De,Es,It,Nl,Pt,Sv,Da) to make all of the achievements. I'm honestly not sure if any other versions exist or if they might work. You do not unlock any of the spell leveling achievements by opening the various chests within the Card Collector's Club. They must be earned in battle, so if you care to get the achievements for Harry learning Vermillious Tria, Verdimillious Tria, Incendio Tria, and Mucas Adnauseum Tria, wait to open the Transfiguration, Music, Hogwarts, or Curses chests. Emerald Firecrab, Dark Goblin, and Doxie Queen have been removed from their respective Folio Bruti achievements because I was unable to locate them. If anyone manages to encounter any of these, please contact me. It is worth noting that all minigames played within the story (not chosen by clicking Mini-Games on the Title Screen) are on Easy difficulty; therefore, you cannot unlock achievements for playing minigames on other difficulties within the story. The missable achievements are "Helping the Less Fortunate" (before leaving the Burrow), "Amphibian Wrangler" (before leaving Diagon Alley), "Dueling Champion" (before dueling Draco), "The Price of Victory" (You have to win), "Earning Some Respect" (You have to win), "The Last Ingredient" (You have to win), "Petrificus Totalus Tria", and "Fumos Duo" (Hermione goes in and out of the party).

WARNING!: "COMBO COMPLETIONIST" WILL NOT UNLOCK IN RETROARCH. The special type of address used to store items, cards, and combos in both this game and "The Sorcerer's Stone" are a unique feature of the Gameboy Color, and they are constantly being adjusted depending on the specified memory bank. RetroArch and RALibretro cannot read them properly, and achievements containing conditions with these addresses will not unlock in these emulators. I was able to find alternatives to using the card and item addresses but was unable to do this for the combos. If you plan on playing this game in RetroArch, I would advise making backup saves as you get close to completing your Folio Triplicus. Then, when you discover the 40th Card Attack Combo, you can rename your copied .srm file to .sav, open the game in RAVisualboyAdvance, and the achievement will unlock when you receive this final combo.

Now for those new to this game, the ordering for the first 19 story-related achievements is not absolute. The side quests (mainly A Considerate Teammate, The Final Exchange, Dueling Champion, and Handling Ghosts) can be completed at any time after they first become available, but you should complete "Dueling Champion" before your duel with Draco. There are numerous items hidden throughout the game, so search things like bookcases and desks. Also, there's a new game+ in which you keep your level and the contents of your Folio Magi, Folio Triplicus, and Folio Bruti. Don't fret if you think you missed something. You will most likely have to play through the game twice, once with the Merlin deck and once with the Morgan le Fay deck, in order to obtain all of the cards and combos anyway. Below is a quick list of places in and around Hogwarts for those unfamiliar with the game. If you are ever unsure of your current location, press the select button to find out where you are.

Hagrid's Hut: southwest of the castle entrance
Herbology: in Greenhouse 2, west of the castle entrance
Quidditch Pitch: southeast of the castle entrance
The Dungeons: through the door the left of the staircase in the Entrance Hall

Weasley Emporium: to the right of the staircase in the Entrance Hall
Moaning Murtle's bathroom: on the second floor, to the left

History of Magic: on the fourth floor, to the left
The Hospital Wing: on the fourth floor, at the top
