Harry Potter and the Prisoner of Azkaban (Game Boy Advance)

Harry Potter and the Prisoner of Azkaban seems to be based off its Game Boy Color predecessor, including some unused data from that game.

Debug Menu
This game has a fully intact debug menu. To access it, enter the Action Replay / Gameshark code. Then, during the game, press the AR (GS) Button.

Pressing the B button on the main debug menu will return to the title screen.


 * Map Select - Allows you to spawn at any map in the game, including the test ones below. This option will use the settings chosen under the Character Level and Quest Select and Party Member Select sub-menus.
 * Character Level and Quest Select - Allows you to modify the levels of Harry, Ron, and Hermione, as well as the current quest. The levels for each character go from 0 to 99, while the Current Quest setting goes from 0 to 26. When exiting this menu, the A button will confirm changes, while the B button will discard them.
 * Party Member Select - Allows you to change the Lead Hero as well as the Second Follow and Third Follow characters. Unlike the above menu, both the A and B buttons will save the settings and exit the sub-menu.
 * Possible characters are: Muggle Harry, Muggle Hermione, Muggle Ron, Muggle Harry Lumos, Muggle GBC (Harry from the Game Boy Color prequel.) Harry, Robed Harry, Robed Hermione, Robed Ron, Buckbeak, and None.
 * The game will let you select the same character in multiple slot. Battles will freeze if there are no heroes in them (i.e. your party consists of only Buckbeak(s)), and the game will graphically glitch or reset if all character slots are set to None.
 * Test Sound and Music - Play any of the sound effects (numbered 0 to 178) or music tracks (numbered 0 to 51) from the game.
 * View Collector's Cards - Use the D-pad to flip through all of the Collector's Cards in some sort of almost-numerical order.
 * View Portraits - Use the D-pad to flip through all the character portraits. Going past the left and right bounds causes graphical glitches, eventually looping back to the other side of the portrait list.

Developer Text
There are some error messages starting at hex address 0x60555. Error: Send Overrun Error: Recv Overrun Error: Recv CRC Error: Recv Missing Packet Error: Invalid Mode Error: Invalid Command Error: Timeout Error: Game Code Recv Error: Game Code Send Error: None

Test Rooms
Five maps make up the test room. They are titled Diagon Alley Test Map 1 through 5. These maps can be accessed through the Map Select function of the debug menu. Despite the name, there are no features of Diagon Alley in the levels. These maps are linked horizontally and in numerical order. Each room has unique sprites. Any sprites with walking animations walk in a continuous loop. Entering a magical encounter results in a hanging battle screen with two "Monster Book of Monsters".

Unused Minigame
In this minigame, Harry has to play the infamous arcade game "Tapper" (But he serves Pumpkin Juice instead of Budweiser). The sprites for the "customers" are randomized every time the minigame is started. The customers will move towards Harry slowly. Once a sprite reaches the end of the table, it's game over. Controls: Use Up/Down to move between the three tables. Press A to fill and slide a glass of Pumpkin Juice along the current table. There is no function for receiving Pumpkin Juice, so the glass slides past the sprites and falls to the ground. This results in a YOU LOSE notification. Pressing the L button at any time brings Harry to the center table, where he drinks a glass of Pumpkin Juice and throws the empty glass on the ground, giving Harry 400 points. This results in a LEVEL PASSED notification.
