I'm trying the game again...ordering Yasu to start tapping when there's nothing obvious in sight is practically screaming for a reference to "The Red-Headed League". (Sherlock Holmes tests to see if his hypothesis that the conspirators are digging a tunnel into the nearby bank is true by tapping on the pavement with his cane.) It'd probably be too clunky to fit, but just running it past you...
EDIT: Are you sure you didn't accidentally break parts of the game? Just for fun, I tried "Stop the Inquiry" and it just loops me over and over to the same dialogue. And just now, I tried using the "Show an Item" option in the Interrogation Room and Yasu tells me Yukiko said Hirata told her he was going to Kyoto...problem is, I hadn't interrogated her yet. -_-;
Are these bugs present in the original?
EDIT #2: What the hell. I forgot I still had the original version. :p
My God...may I ask, whose idea was it to use those great big clunky menu commands? The Japanese menues (not to mention font) are much cleaner and more elegant...I would have gladly truncated sentences just to keep that. "Move", "Ask", "Files", "Show", "Search", "Call", "Arrest", "Examine", "Items"/"Evidence", "Tap", "Take", "Review", "Dial", "Quit". You may have qualms, but trust me: the translation would only benefit from a nice, clean-looking typewriter font to match the Japanese version's style.
And how was I supposed to learn about Yukiko to begin with? First time I heard of her was when Yasu piped up about something I wasn't supposed to know yet.
EDIT #3: This is getting long, isn't it?
Anyways, I'm stuck. I know there's a secret door in the study where Kouzou was killed and that I'll be damned if it isn't in the right-hand wall. I know that Hirata was last sighted at a temple in Kyoto (though I don't have the slightest idea where he's gone now), Toshi's involved in drug smuggling, Komiya is too vehement in his denial to be clean, Sumoto will play a major role in the story's development and/or denouement and that the 000000000-whatever phone number is pretty much worthless. Oh, and that there are people under the mansion. Trapped? Performing dirty deeds? Both? I know it's gotta have something major to do with the storyline. And what the hell does that stripper Okoi have to do with anything?
