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). 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.
