Only "Susie" doesn't work, it's now stuck
executing these instructions:
   $00016690 : btst   #0,$fffffc00.w    50.00%
   $00016696 : beq.s  $16690            50.00%

Nicolas, any ideas what could be the problem?

Hi

if you look at the code after, you can see that the btst is in fact waiting for a byte to be received from the ikbd ; which means a key was pressed (or mouse was moved). then just after, it compares the content of fffc02 with #$01, which is the scancode for the 'esc' key.

So, demo is not stuck ; press 'esc' and it will continue. In fact it exits. I don't know it's supposed to run sthg instead of exiting, someone would need to test on a real falcon. (or look at the source code with the demo)
