SUL to HRU Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.
