Thanks!  I downloaded this and tried it under WinAOS.
I had to make some changes because WinAOS doesn't
use the same CRC as does the latest "crazy fresh"
BlueBottle release.  I put my changes at:


Alternatively one can recompile CRC using the latest
version.  (I'm not sure what that would do to WinAOS
in it's current state.)

I'm also curious as to why the picture is flipped.
BlueBottle must be using a different coordinate
system.  It should be a relatively easy fix though.
