Hi Carlo,
Home now and have taken a look at 1.4.
To be honest; the main game files are the same size as the ones in 1.2.
The only addition seems to be the ability to set "CD replay and CD.ini":
I've used "GetCDID uaescsi.device 0" to grab the ID String. I've put this into the "CD.ini" file and also launch the game with "-cddevice uaescsi.device" + "-cdunit 0".
Game loads fine and says "Current CD: Tunnel B1" but unfortunately no music though:
Did you have any joy with music?
