What is Meitantei Conan - Nishi no Meitantei Saidai no Kiki! (J) [M]?

Compiled by Alfred J. Hall · Editorial standards · Published June 28, 2026

This is Meitantei Conan - Nishi no Meitantei Saidai no Kiki! for the WonderSwan, a handheld that Bandi pushed as a competitor to the Game Boy in Japan. It is a detective adventure game based on the popular manga and anime series Detective Conan (Case Closed in some regions). The exact release year and developer are not widely documented, but it dropped during the WonderSwan's commercial life in the late 90s or early 2000s, exclusively in Japan. The "[M]" in the filename likely indicates a revision or release variant, not a fan hack.

The player takes on the role of Conan Edogawa and works through a mystery narrative. The core loop involves talking to characters around a hub area, examining environments for clues, and making choices that advance the story. It plays like a classic graphic adventure with visual novel elements, leaning on text and static scenes rather than complex action. You navigate menus with the D-pad and confirm selections with buttons, progressing through a branching plot that requires smart deduction.

For fans of the series, this is a neat piece of Detective Conan history on a niche console. The WonderSwan had a limited library of licensed games, and this one captures the investigative spirit without oversized mechanics. If you are into retro handhelds or want a pure text-driven mystery in Japanese, it scratches that itch. Just be ready for the language barrier since there is no English translation.

How to Play Meitantei Conan - Nishi no Meitantei Saidai no Kiki! (J) [M] Online

Since Meitantei Conan - Nishi no Meitantei Saidai no Kiki! is a Japanese game, all text is in Japanese. When you start, you will probably see a title screen. Use the D-pad to navigate menus and press X (A button) to select options. If there is a "Continue" or "New Game" choice, the top option is typically new game.

The game is a text adventure. You will explore a few locations, talk to people by selecting dialogue prompts, and pick up items by examining scenes. The core loop is advancing the story by making the right decisions. If you get stuck, try talking to every character again or examining everything twice. The game tends to be linear once you figure out the next clue.

Because the controls are simple, you can use X to confirm and S to cancel or go back. Some menus might have a cursor; use the D-pad and press X to select. There is no time pressure, so take your time reading (or using translation tools). The Select button (V) might open a map or inventory in some WonderSwan adventures, but it is not guaranteed to work here.
