I've mentioned 'pro' because you need some basic understanding of MAME, File and storing methods. It *is* easy to use if you spend 5 minutes and got the basic knowledge of MAME and its storing methods. If you're a neogeo kiddie who wonders why Samurai Showdown 1293812 doesn't run anymore, tough luck, I don't care. Users are always welcome to raise requests/ideas at the cmpro forum....
