Change Log

  • fixed: memory corruption and random crash during sethash generation
  • fixed: disabled softwarelists with non-unique assigned paths could lead to wrong missing set messages
  • added: set information copy2clipboard context menu to generate set lists
  • misc: updated 7z library and sdk to 15.09

Vista/Windows7/8/10 user note:

If you install cmpro to a protected folder like C:\program files\, you have to set the compatibility properties of cmpro.exe to 'run this program as administrator' to work correctly or you have to disable UAC. In other folders it should work fine without setting this property and without the need of disabling UAC.

Linux WINE/Mac Crossover user note:

If you got problems with the main window, set the option 'Adv_HideWindow = off' in cmpro.ini. In case you don't have a cmpro.ini yet, create one with the following two lines:
Adv_HideWindow = off

Windows 9x/XP Users:

Update your OS!


How to use this piece of software...

4.025 (2015-10-12)

  • misc: better support for UHD screens (button bar, statistic window output, initial default size of sizeable windows)
  • misc: updated unrar library 5.30.5
  • misc: updated 7z library and sdk to 15.08
  • fixed: crash when going from profiler create to scanner setinfo
  • fixed: exception when loading of 7z dll failed
  • fixed: evil romcheck skip when chds of the set are missing and the archive is stored in the same path
  • fixed: re-fixed wrong placed/unneeded chd detection problem when setnames share the same name across software lists
  • fixed: showing wrong bad chd checksum messages when setnames share the same name across software lists and one chd is missing
  • fixed: unneeded set check marks some sets as unneeded when you have a pretty uncommon setup where chds in the dat are listed as roms with subfolders

4.024 (2015-09-23)

  • fixed: cmpro still shows a wrong checksum message for unneeded chds even after removing them
  • fixed: general 32bit cut down issue when calculating size/checksums of files in zip64 archives
  • misc: xml datfiles with "machine" elements instead of game elements are parsed, too
  • misc: xml datfile export (either setinformation or dir2dat) uses "machine" as set element (cmpro.ini Adv_SetElementXML value holds the value in case you want to change it to "game")
  • misc: updated zipclass library to 4.6.2
  • misc: updated unrar library 5.30.4
  • misc: updated 7z library and sdk to 15.07
  • misc: ah yeah, if you don't know already, zip64 format now is officially supported

4.023 (2015-09-18)

  • 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)

4.022 (2015-08-29)

  • misc: new compiler (VS2015) under Windows 10 Pro
  • misc: 7z/rar warnings are now shown in the warning window, not as a messagebox anymore which you have to click
  • misc: profiler move/add datfiles overwrite prompts support yes/no to all
  • fixed: wrong "wrong case" set message when a chd is missing
  • fixed: 7z/rar detection of obsolete folders fails in some cases
  • fixed: datfile nodump flag gets ignored in case of an additional size=0 entry
  • fixed: nodump without any size entry were not imported
  • fixed: wrong rar bad crc message when deleting full archives

4.021a (2015-07-20)

  • fixed: possible crash with corrupt settings file
  • fixed: rare issue where a sample parent set with no samples for its own and multi-softwarelist support is marked as unneeded
  • fixed: possible crash on cmpro start on read-only device or full device
  • fixed: structural issues and possible crash when using dats with releases and run into double name issues
  • fixed: double name check when using releases
  • fixed: some dialogs don't use "MS Sans Serif" as font...
  • fixed: adjusted some warning messages to use [SOFT] instead of [LIST]
  • fixed: setinformation "hide parent" does not work for listed disks
  • fixed: unpacked set with chds can be falsely detected as misplaced
  • fixed: rare typo based bug in checking unneeded sets/chds
  • fixed: hashcollision sets with nodumps can create circular fix-unneeded/fix-missing scenarios
  • misc: better unneeded detection of chds within an identical setnames relation (softwarelists/Non-Software List)
  • misc: better wrong sysdefpath detection of chds within an identical setnames relation (softwarelists/Non-Software List)
  • added: automatically detect mame and mess as xml root elements
  • added: supporting biossets with samples (and sampleof) elements

I may add more ancient version history when I find some more free time...
