It seems the resource volume may be corrupted a bit here. Views 6, 7, 10, 13, 14, 15, and 16 aren't in the file, but all the rest after (starting with view 20 at offset 0xfb03) are there.

The demo seems to be broken. In Dos-Box music plays further, but it stutters a lot and the whole engine goes mad. I don't consider this as a bug per se. We should better try to find the original demo.

Agreed. I'll try to contact the guys over at Sierra Help (where this demo is originally from) to see if they have the original version. The one on their site is broken too.

I managed to "fix" the police quest 2 demo.
The current one had a broken resource.001 file.
In this file, views {4,6,7,10,13,14,15} were corrupt.
I dumped the appropriate views from the real game to the game folder and now the demo works fine.
From the size of the views and their context in the demo I noticed that all but one (view.010) of the views match exactly to the the real game.
View #10 was apparently made just for this demo and is probably showing Bonds walking with his pistol by his side. I replaced this view with view #0 which shows bonds walking w/o a pistol. The view is used in the last scene in the demo where Bonds & Bains walk toward each other. The scene looks fine with view #0 as well so it's not so bad. I guess a recreated view could be drawn by hand.
The fixed demo can be found here: http://hotfile.com/dl/63607950/adcdc46/pq2-dos-ni-demo-en.zip.html
Now the demo works fine in scummvm.

However, you ripped those sprites from the full game. I wouldn't be comfortable distributing this. In any case, I asked over at Sierra Help and they are tracking the non-corrupted version down.

For what it's worth, in DOSBox, the game goes no further but continues to play music.

Reducing the priority of this one, since it's caused by corrupt data
