Summary 04388: specfrce: Wrong SHA1 check sum in XML data for CHD (v3 vs. v4)
Description The stored SHA1 check sum for sf010101.chd appears to be the one from the v3 formatted CHD. After an update to v4 (using 'chdman -update') the header check sum is reported as bad.
Steps To Reproduce Run 'chdman -update' on the CHD and run 'mame -verifyroms' on the set.

 Confirmed. Whomever added it to MAME should have verified the state of the CHD. This will be corrected for next release.
