I have the audio tracks working on my xbox version of ScummVMx
For monkey Island 1 CD Version *cough* a.b.c.i.x *cough*
Ripped the tracks with Audio Catalyst, then used Wavelab to convert them to 96kbs, 22050 Hz, Stereo, CBR.
Named them track1.mp3 to track24.mp3 and put them in the same folder as the Monkey Island files (I have a separate directory for each game under the ScummVMx directory ie: F:EmulationScummVMxMonkey Island)
All work fine ... although there seems to be a slight overrun between tracks when going from one scene to another ... possibly due to the AudioCatalyst ripping stage mentioned above ...
Also - just to make a note - On my PC version of ScummVM, if I encode them to 192kbs - they play really slowly - so you definately need 96kbs for the right speed - the 192kbs tracks didn't work on my xbox version at all ...
Hope this helps
btw: is there any way to stretch/position the screen at all ? coz mine is shifted slightly to the left and some games I can't see the 1st word of sentences ?!
