Many moons ago (circa 2003) I produced a spreadsheet to help me visualise the structure of Jaguar object list objects. Taking the details from the tech ref and formatting them into a more visual representation.
Recently I came to need to make use of this chart again and realised it might be of use to others, so I present it here.
The chart shows each of the five object types and their structure ordered by phases. Least significant bit on the right, most significant bit on the left. Each row represents a single phase (2 longs or 64 bits), but the numbering at the top is for two 32 bit longs.
For meaning of the various bits and names, check with the Atari Jaguar technical reference manual, or other documentation.
