Can't reproduce, maybe I used an unstable/dev version by mistake. I 
confirm HD emulation works and can be accessed from AS fileselector.

BTW, a small "bug" in the intro you added : if you start in STE mode 
with tos 1.62 for example, then DMA sound is used to play the module, 
but key sound is not disabled, so you can hear 'click' when pressing 
keys, which is not very pleasing for the ears :)

This is now fixed ; the problem was that physical size for RAM bank0 and 
bank1 were only computed at start, but not updated when total RAM was 
changed later from the UI and a reset was made.

This could be visible when both size and machine were changed, as STF 
and STE have different MMU mapping for RAM.
Thanks for pointing this.
