You can find all of the current support files for MAME, plus the most popular versions of the emulator itself by going to...

http://www.emulator-zone.com/doc.php/arcade/mame.html

It included all 4 dat files for MAME cheats, Information, History and Hiscores.

A very useful central location to update your files.
