Tantei Jinguuji Saburou - Shinjuku Chuuou Kouen Satsujin Jiken (Japan) (Rev 1) (Disk Writer)

This is a revision of the first Famicom Disk System entry in the Tantei Jinguuji Saburou series, a detective visual novel originally released in Japan in 1987. It was developed and published by Data East. The "Rev 1" label indicates it includes some minor bug fixes or changes from the original disk release. The "Disk Writer" in the title refers to the ability to write the game to a blank disk at Famicom Disk Writer kiosks.

Players take on the role of the titular private investigator, Jinguuji Saburou, investigating a murder that occurred in Shinjuku Central Park. The gameplay is menu-driven: you navigate through locations, examine clues, and interview suspects by selecting text options. The game presents a branching storyline where your choices affect the outcome. The FDS saves progress to the disk itself, allowing for continued play.

For fans of early Japanese adventure games, this title is a landmark in the genre, predating many famous visual novels. The writing is dense and in Japanese only, which limits its accessibility today, but the pixel art and atmosphere capture the gritty detective vibe well. It's a niche title, but those interested in the history of the point-and-click adventure style on Nintendo hardware will find it worth a look.
