Omoikkiri Tanteidan HaadoGumi - Matenrou no Chousenjou on FDS

This is Omoikkiri Tanteidan HaadoGumi - Matenrou no Chousenjou, a Famicom Disk System title that launched exclusively in Japan. The game is part of a series centered around detective work and puzzle solving, though exact release details are not widely documented. It uses the blue disk format typical of Nintendo's add-on drive, meaning it loads relatively quickly for an 8-bit game. The full title roughly translates to "Thorough Detective Team Hard Group - Challenge of the Skyscraper," and it leans into a mystery adventure theme rather than action. The player controls a detective trying to solve a case within a high-rise building. While specific mechanics are not fully recorded, the gameplay involves exploring floors, talking to witnesses, collecting clues, and solving puzzles to advance. It uses a menu-driven interface common to Japanese FDS adventure titles from the late 80s. Much of the text is in Japanese, so navigating menus can be tricky without language knowledge. The game relies on logic and observation, not reflexes. Today, Omoikkiri Tanteidan HaadoGumi - Matenrou no Chousenjou is a curiosity for FDS collectors and fans of obscure detective games. It captures the experimental spirit of the FDS library, where developers tried narrative-focused ideas on limited hardware. It is not a flashy action game, but rather a slow-paced puzzle adventure that rewards patience. If you enjoy unearthing rare Japanese titles and have an interest in early detective games, this one is worth a look.

How to play Omoikkiri Tanteidan HaadoGumi - Matenrou no Chousenjou online

Getting Started

When you boot the game, you will be greeted by a title screen and then a menu. Since the game is entirely in Japanese, you will need to rely on pattern recognition or a translation guide. The start button (Enter key) usually begins the game, and the select button (V key) may cycle through options. Use the D-pad to navigate choices.

The core gameplay involves moving a cursor or character around static screens. You will examine objects, talk to people, and pick up items. Progress is made by using the right combination of clues and items. The menu system likely has options for "Talk," "Look," "Use," and "Move." Try pressing the A button to confirm an action and B to cancel. Save progress is handled by the FDS disk system, which writes to the disk after certain events.

Pay close attention to dialogue and environmental details. Many puzzles require remembering a number or an order. If you get stuck, experiment with using items on objects or people. Keep a notebook handy for Japanese characters that might repeat. This is a slow-paced game meant for careful thinking, so don't rush.
