MAME Classic 9.9.0 has been released. Changes in this version will require your options.ini file to be rebuilt so upon first launch you will be taken to the Options form. This release:

Changed : MAME Classic no longer adds the depreciated "NULL (not set)" text for entries in the mame.ini without a value.
Changed : MAME Classic will now create the mame.ini file in it's temp folder to avoid possible conflicts with other ini files.
Changed : Software lists will now only display software which is compatible with the selected machine.
Changed : The BIOS Filter now shows the BIOS description and filters more accurately.
Changed : The Exit routine has been cleaned up to prevent the app from crashing on exit under rare conditions.
Changed : The MESS Machine listview can now be sorted.
Changed : The MESS Machine listview would show non-installed machines in black if they didn't need a ROM but still needed a device file. These machines now show in red.
Changed : The Options form is now one scrolling page instead of two pages.
Changed : The Path selections now let you select multiple paths for ROMs and Artwork.
Fixed : Exporting a software list would fail if any filters were applied.
Fixed : A crash caused by output file biosmame.txt growing so large.
Fixed : Software Installed/Non-Installed option buttons could be greyed-out even if a selected machine has software.
Removed : Path selections for Other MAME ROMs, Ini and Comments.
