#11773: CINE: OS (Atari ST) - Incorrect intro speed
--------------------+-------------------------------
Reporter:  laenion  |      Owner:  (none)

--------------------+-------------------------------
 When testing the game I had the impression that the game's introduction
 sequence took way too long. And indeed: When playing the game on the Atari
 ST I discovered several inconsistencies.

 Examples:

 Code card introduction text (from cursor appearing to OK button):
 Atari ST: ~ 14 seconds
 ScummVM:  ~ 29 seconds

 Delphine logo (from first shapes appearing to logo faded out):
 Atari ST: ~ 13 seconds
 ScummVM:  ~ 22 seconds

 All in all ScummVM requires 2:34 minutes until the briefing, the real
 hardware requires 2:00 minutes - and that is even though on real hardware
 the loading times are way longer than on a modern PC, for example 10
 seconds for the transition between the hangar / airfield scene in the
 original vs. 0 seconds in ScummVM.

 The problem is that sometimes the speed is mostly correct, sometimes it
 takes twice as long as the original, and everything in between. I have
 uploaded a ScummVM recording of the introduction to
 http://digitalimagecorp.de/files/ScummVM_OperationStealthIntroSpeed.ogv,
 the correct speed can be seen in
 https://www.youtube.com/watch?v=tDmLJ2V697s (the video is matching the
 speed of my Atari ST except for loading times).

 The ingame speed seems to be correct.
