Roman Scherzer's ClrMamePro has been updated to v4.023.
Further details can be found here:
http://mamedev.emulab.it/clrmamepro/ or below.
fixed: cmpro did not mark old chd files (replaced with identical named but different checksum files) as unneeded
fixed: cmpro oversees some unneeded chds (dupe) chds in sysdef paths when the correct chd is also present (quizard sets)
fixed: cmpro doesn't warn about some unpacked rom files within chd subfolders if a rom archive also exists
added: setinformation "initial invert" option, which inverts your selection on database load (so you need to manually hit the invert button)
