That's because the image of the wizard only available for the VGA and SVGA modes. I think that's why we don't see it in other graphics modes.
Can't confirm that machine=tandy doesn't work. You need to launch the game with game -dis t -w16384

However nobody actually noticed the PCjr regression. Also I found out that the game will be frozen and only the mouse works. Can't type anything and after quitting the game can't do anything in DOSBox. I can't input any commands.

OK so here's the funny part. I found what causes the issue. If I type something it won't be shown on the screen unless I move the cursor around. I found this out when I was trying to record 0.74 with PCjr to show that the bug is not present. However I found weird that this can't be done in the SVN which is really odd.
Eddie@time there's nothing wrong with the audio. It should be only on the startup screen. There's no other audio options in the UI.
