About This File
In the newer versions of MAME there has been a change to these files adding a .key file that is needed to run on the latest versions this also keeps them from working properly with the FBA core in RA also. I didn't have the latest version separate with my CPS2 stuff so here is a .bat to extract them from the latest MAME source you can use them to overwrite your old files and everything will work with the latest emulators.
