+// Vohaul's scene on the PocketPal (room 545) is incompatible with our dual
+// text+speech mode and reportedly has MIDI timing issues in text mode.
+//
+// This is an unusual scene in that it uses three empty MIDI songs to control
+// its text delays, which is probably why Sierra didn't fully upgrade it to
+// use a Narrator in the CD version. Instead the tVOHAUL Narrator is only used
+// in speech mode without the formatting it would need to display text. In text
+// mode the original floppy code handles that.
+//
+// We heavily patch this script to support text+speech mode and remove the MIDIs
+// from the equation. The trick to using tVOHAUL in dual mode is to set its
+// nMsgType to 2. This causes Sq4Narrator to change the game's message mode to
+// speech while it says a message, preventing it from displaying text in a
+// message box since it wasn't provided formatting. Our code needs to know the
+// real message mode while tVOHAUL is speaking so we store that in the script's
+// register for later use.
+//
+// The audio and text for Vohaul's messages aren't the same. The audio for the
+// second message also contains the third, and the third has no audio resource
+// at all. We work around this by setting a three second timer and displaying
+// the third text while the audio is already playing.
