A little feedback for polish and QoL. Very minor spoilers below so I'm pushing it past the read more button...

1. When you press a statement during cross in Ace Attorney and the game returns you to the testimony, it puts you at the next statement. Here, you're returned to the beginning. This can make it harder especially for players unfamiliar with that gameplay loop to keep track of where they were in the line of questioning. Hell, I found myself accidentally pressing the same statement repeatedly a couple times because I forgot which question I pressed before.
2. I like how you've flavored the "Objection," "Hold It," and "Take That" interjections. However, given how they're phrased, I feel like there are a number of places in the dialogue where using the "Stop right there" (Hold It) shout should be used instead of the "No, that's wrong" (Objection) shout, e.g. when the "prosecutor" starts being dehumanizing and the scrivener insists he cut the crap and show some respect.
3. Would it be possible to add the "skip dialog" button present in the normal interface into the turnabout interface? Or does the courtroom scene code make this a pain to do?
4. In general I feel like there should be a way to still easily pull up the logbook, "court record", or dialogue history when presented with a multiple choice option in both the standard and courtroom interfaces. To draw a comparison, to my recollection Ace Attorney keeps those button prompts visible on the screen at practically all times, the normal MonVillage interface disappears entirely during a choice and the dialogue history and log book aren't options on the courtroom interface.
5. If I'm using Skip Dialog to fast forward in Chapter 3 and the game gets to a "save your game" prompt, the VHS static persists on the top and bottom of the screen until the actual save screen appears.
