Shin Megami Tensei: Devil Children: Kuro no Sho and Aka no Sho

Devil Children: Black Book and Red Book
Developer: Multimedia Intelligence Transfer Publisher: Atlus Platform: Game Boy Released in JP: November 17, 2000 This game has unused graphics. This game has debugging material.

The Devil Children Gameboy games are a spin-off sub-series from the original Shin Megami Tensei series. While the tone and moral ambiguity are still 100 % megaten, the game features Pokémon-style gotta-catch-'em-all feeling and lovely graphics side-by-side a complex devil fusion system and tough random encounters.

Translator's Note: The name Debidasu - used for your list of collected Devils - is a Japanese pun on the term "Debiru wo Dasu" (Sending Out The Devils) that doesn't translate particularly well to English. For ease of reading, the translation on this page will translate to Devilist.

Main Debug Menu

• 

  The remaining Debug Menu

• 

  Debug Menu with developer name and build date mockup.

This is the main debug menu. It appropriately calls itself "Debug Window" (デバッグ　ウィンドウ) and indicates whether debug is on (デバッグ　オン) or off (デバッグ　オフ). You can use the GameShark cheat above to enable debug mode.

Notice the first line will be garbled in any release version of the ROM, because the appropriate version name/tester name and development date have been left out of the final build. The mock-up on the top right shows a possible developer name and build date.

Accessible function menus include, in chronological order:

Switch Maps (マップいどう): Change the current map. Monster Display (モンスターひょうじ): View all monster pictures in the game. Group Check (グループチェック): Check all possible combinations of enemy groups that may be encountered. People Menu (じんぶつ): View all people and monster in-game mini-sprites. Enemy Encounter (てきしゅつげん): Set or reset the enemy encounter flag. Flag Check (フラグチェック): Set or reset the game's event flags. Sound Check (サウンドチェック): Listen to background music and play sound effects. Effect Check (エフェクトチェック): View battle animations and other effects.

Event Art (イベント１まいえ): View scrolling event art and play effects over them. Cable Connection Check (つうしんチェック): Check the cable connection and protocol and send debug data packages between two Game Boy (Color) consoles. Save/Load (セーブ　ロード): Save, Load or Erase your current game progress. Obtain Ally (ナカマにゅうしゅ): Obtain any monster as a new ally. Trade Sequence (ツウシンエンシュツ): Watch the Link Cable trade animation sequence. Key Items (トクシュアイテム): Determine which key items the hero currently holds. Devilist Check (デビダスチェック): Check the devilist and set or reset the seen/captured flags.

In addition to these options, unused menus and older, broken menus are scattered between the accessible ones. They will be dealt with as well as far as possible.

Start Menu Debug Mode

GameGenie Codes

• 

  Selecting the level option.

• 

  Changing hero's level.

• 

  Selecting the money option.

• 

  Using the money entry box.

The Start Menu Debug Mode at 4F:5728 allows one to freely edit the hero's level and money held. To activate it, use the above GameGenie codes and choose the save (セーブ) option from the Start Menu. The game must be on debug for the option to work, see above, else it will not enter the debug mode.

• Navigation: Use Up/Down to choose either level or money to manipulate. Use Left/Right when the level is selected to Decrease/Increase it. Use A/Left/Right when the money is selected to trigger the money entry box. B will exit this debug menu.
• Money Entry Box: Use Left/Right to choose the digit to manipulate and Up/Down to Increase/Decrease the digit's value. Use A to accept the new amount of money or press B to cancel and return to the previous menu.
• Tidbits:
  • The money entry box was supposed to be set to 9999999 Makka when opening it. However, a subsequent change in programming of the money entry box changed the scratchpad location.
  • The graphical errors that are visible when the money box is opened are due to the box using fixed alternate tile positions for its digits and Makka sign instead of the usual ones. The graphical errors have no impact on functionality.

Item Bag Debug Mode

• 

  Before using the debug cheat.

• 

  All items were granted 99 times.

The Item Bag Debug Mode at 4F:56CD grants one access to all items in the game that can appear in the item bag. Use the above GameGenie cheat code and choose Use (つかう) in your item bag. The debug option need not be activated for this to work.

• Tidbits:
  • This will give you unused items Item043 and Item044 (アイテム０４３ and アイテム０４４).
  • The Special Items menu (とくべつ) will actually be buggy, because it is supposed to hold 35 items, while the maximum allowed for any menu is 32 items. A buffer overflow occurs.

Monster Status Debug Mode

• 

  Activated debug mode.

• 

  Edited monster stats.

The Monster Status Debug Mode at 4F:5838 allows one to freely edit any Monster's status attributes as well as level, HP and MP. View the Monster Status screen in your VineCom or VineCenter and press A to activate the debug mode. The game must be on debug for the option to work, see above, else it will not enter the debug mode.

• Navigation: Use Up/Down to select the status attribute to manipulate. Use Left/Right to Decrease/Increase the attribute. Press A or B to exit the debug mode.
• Tidbits:
  • There is actually a bug when editing HP or MP. When going from 999 points to 001 points, the counter will stop at 1000 points, which won't work correctly. You have to tap twice to go from 999 points to 001 points, or you can use the GameGenie fix from above.
