Help needed, Opera scene in 50Hz

I'm almost finished fixing an old Swedish translation of FF6, I have you guys to thank for a lot!

I would love to have the game running in 50Hz, to accomplish this I'm using d4s old patch, romhacking FF6 PAL-fix
It works just fine until you get to the famous Opera scene where it all breaks down.

The main problem is that the F9 01 command at CA/BB2B doesn't work, it is supposed to pause event execution until the song has passed a specific point.

Here is the script (Can't seem to find the correct page on datacrystal, this is from the event disassembly)

Code:

CA/BB20: 31    Begin action queue for character (Party Character 0), 6 bytes long 
CA/BB22: C1        Set vehicle/entity's event speed to slow
CA/BB23: 82        Move vehicle/entity down 1 tile
CA/BB24: E0        Pause for 4 * 48 (192) frames
CA/BB26: 82        Move vehicle/entity down 1 tile
CA/BB27: FF        End queue
CA/BB28: 4B    Display dialogue message B9, wait for button press (Show text only)
               The next line is…?
                  ^(Oh my hero…)
                  ^(Alas, Draco…)
CA/BB2B: F9    Pause execution until the music passes through predetermined point
CA/BB2D: B6    Indexed branch based on prior dialogue selection [$CABB3D, $CABB35]
CA/BB34: FE    Return

Is it at all possible to fix this? Any suggestions are dearly appreciated!
