I've just tested 0.93. I can't see any issues. I did get a few less games, but I probably need to update my roms. Galaga seemed to be there. By default the update is based on the XML list of roms from MAME and a Verify of your ROMS. In addition the Only Working, Allow Imperfect, No Clones, No adult, and Filter settings It is probably just a MAME issue. They make tons of changes throughout the versions. A few versions back all Neo-Geo games would not verify until you got a new file. Although I think they did run in MAME32. So the obvious thing to do would be turn off the Verify, or get the latest roms and audit them. You can also have the update check against file rom names on the hard disk, or list everything. Basically unless you know what your doing and can obtain new roms easily, updating to a newer MAME version will probably mean you have less games to play. Tom
