《小叮噹/哆啦A夢》(ドラえもん 対決ひみつ道具!/Doraemon: Taiketsu Himitsu Dogu!!)是由SAS Sakata開發，Epoch負責發行的Game Boy單人遊戲，於1991年3月1日上市。遊戲記憶體為1M，並提供輸入三個字的密碼來續關的功能。

遊戲與紅白機版本（Famicom）相似，關卡由仰式角度和橫向捲軸畫面組成，敵人會直接出現在平面上。透過十字鍵來進行方向的移動，仰式畫面按Select鍵可以顯示地圖，而橫向移動則是切換武器。不論哪個畫面，按A鍵能發射武器，在橫向移動的畫面中，按B鍵就能跳躍。

遊戲共有五個關卡組成，來到迷宮時需要搜尋攝影舞台的入口，並救出被當作人質的大雄、小夫及靜香等。吃到銅鑼燒可以增加一條生命，而秘密道具共有16種，武器包括拳頭、子彈和迴旋鏢等。被敵人擊中後會馬上死亡，除非有特殊道具保護。

進入任意門時，可以與老實娃娃/正直太郎聊天並蒐集情報。找到正確的門就可以移動到其他空間，也可以抵達宇宙和海洋，但是需要解鎖道具，當任意門關閉時就無法進入。三個不錯的密碼:まてき、へいき、さかた。

"Doraemon: Taiketsu Himitsu Dogu!!" is a Game Boy single-player game developed by SAS Sakata and published by Epoch, released on March 1, 1991. The game has a memory size of 1M and provides a feature to input a three-letter password to continue the game.

Similar to the Famicom version, the game features levels composed of both overhead and side-scrolling perspectives, with enemies appearing directly on the screen. Any movement is controlled using the D-pad, and in overhead view, pressing the Select button displays the map, while in side-scrolling sections, it toggles weapons. Regardless of the perspective, pressing the A button fires the weapon, while the B button allows jumping in side-scrolling segments.

The game consists of five levels, where players must search for the entrance of the maze and rescue hostages such as Nobita, Takeshi, and Shizuka. Eating taiyaki increases one life, and there are 16 secret items, including weapons like punch glove, pistol, and boomerangs. Getting hit by enemies results in instant death unless protected by special items.

Players can chat with Honest-toy/Verity Tarou and gather information when entering any door. Finding the correct door allows moving to other spaces, including space and ocean, but requires unlocking items. When any door is closed, entry is not possible. Three good passwords: まてき、へいき、さかた.
