Yeah when a system is selected it will show a different screen/theme. You can also do it with other screens besides emulators (music,jukebox,radio etc) You have to enable custom emulator layouts in the theme editor (Edit/Options).
A guy was caught in Canada hacking into the Canadian Revenue Agency attempting to steal Social Insurance Numbers, I think there is details on the BBC News site.
Cool, I must overlooked that Mame Offender post. I think you missed my score above GC. I love the ending on this game when all the characters escape from the arcade machine and run down the street.
