Thanks for your answer !
And so, is there nothing to do with the audio issue ?
By the way, I noticed another strange thing. In the last level of TR2, in some cases, the ending cutscene is cut before it ends, and in other cases, everything is normal.
Here for example, it's normal :

Here it's not :

So what is the origin of this difference ?
Concerning dgVoodoo, the waving background and coloured health and breath metres, does it work with the GOG version ?
It looks really cool !
Do you know a video where we can see this please ?
