@leech_hunter I think I wrote something that will do it - it is running on my local machine. Before I upload it and announce it, can you help me test it? Can you send me (via message or here) your Arcade.xml (In the Launchbox/Data/Platforms folder) This will help me test it.
So far it gets almost everything on mine (working on 720 degrees), but I don't have too many mame games.
Thanks
