Hybrid Heaven hangs at the end of the game...

I have a PAL version of a Hybrid Heaven ROM, and it hangs at the end of the game -- right after my fight with both of those huge monster things. When someone's grabbing the elevator. The ROM is good (I checked it with GoodN64).

I'm using the following plugins on PJ64 1.5:
Jabo's Direct3D6 1.5
Jabo's DirectSound 1.5
NRage's DirectInput8 v2 1.80a
