Finally, it's been solved - don't thank me, thank the dude who posted on wikipedia.com...
Firstly, this only applies with DosBox version 0.65. This assumes you've already installed and configured the game (I use Full Install, SB16 and General MIDI)
Edit your config file as follows:
output=overlay
cycles=auto
core=dynamic
mount d d:\ -t cdrom -usecd 0 -ioctl (*optional* - saves retyping).
**note: It's a liitle jumpy at the start of cutscenes until the cycles adjust. But it's nothing at all to worry about because you'll be flying like you should at the correct speeds.
Hope all this helps.
