--- Comment #27 from Christopher Thielen christopher@thielen.co --- Some kind person wrote tools for examining the data files: http://bursik.de/ultima/tools/downloads/u9tools.zip.
I'll try later to figure out at least where the missing cursor image/resource/icon is kept in the data files (maybe the bitmap*.* files) and see if I can't trace where it gets loaded and what happens to it from there, e.g. used as a cursor, turned into a D3D surface, etc.
