Is this playable on some version of MAME?
Post #15 in this thread ( [link removed by mod] ) has a link -- download and replace the files in your tapper.zip file with these (note this replaces the originals so be sure to make a back up of the originals first if you plan to revert -- Not sure if there is any mame FE that will let you use both or what the zip would need to be named if there is !)
Oops - forgot not to link !! Anyone looking for the link can go to Klov and search and should be able to find the thread
