Do you have any walkthrough on how to reach that scene? or a save file (if the game has saves)?
I've found a similar issue in emulators:

and it's related to the cd seek time. Do you have seek time emulation enabled? if it is, maybe I need to increase it a bit.
Edit: Just tried it with seek time emulation on and off. It works with seek time on, hangs when off. I'll force it to on for this game in the next firmware.
