Skip FMV

Sep 7 at 6:05 PM
Is it possible to somehow skip FMV? I am thinking about Final Fantasy IX, containing a speed-run sidequest.

On real PSX, I can open and close the tray in order to skip the video; I tried to do this by switching ISO files but it didn't work.

Any idea? Replacing FMV in the image with very short video would also be fine.
