I just got the Gyakuten saiban jazz arrangement and i love it, i was wondering if theres any more jazz arrangements like that with other games. I searched and found nothing.

I have two recommendations:
- Chrono Trigger - Brink of Time
- Rockman X Alpha Lyla with Toshiaki Otsubo

Both are hosted on Galbadia Hotel.

I'd also like to recommend track 8 from the Gyakuten Saiban Orchestra Album, "Godot ~ The Aroma of Black Coffee," assuming you haven't heard it already. Although it's considered orchestral, the saxophone makes it pretty jazzy.
