It links fine over here at least. So I'm unsure what you mean with this 
point :-).

One thing which I find particularly annoying is that when you enable the 
keyboard all game / GUI interaction is stopped. For example when trying 
to enter a save game name in GMM's save dialog via the vkbd it will not 
be displayed while using the vkbd. The whole input will only be shown 
after the vkbd is closed. I guess that's already on some TODO list 
though :-). It would probably require backend internal handling though, 
since currently the vkbd is just drawn on the overlay, which might lead 
to conflicts when the GUI would be updated while the vkbd is shown.

Actually adding support for another BMP format in the loader code 
shouldn't be too hard. We would probably need to store the data in 
memory in overlay format thus 16bpp though, everything else would slow 
down drawing of the vkbd. Of course depending on how often we need to 
redraw that might be acceptable.
