Received this email from Jonathan...
"The turret tower chd has an unexpected offset applied to the data on it, possibly caused by it being ripped using an old, buggy-geometry version of chdman; can you re-rip the hard disk using the new (latest mame version) chdman, and see if the checksum matches the old rip?"

Re-did a chd using version 0.133
Ended up being 12 bytes shorter
