Yes. Perhaps I am not certain of what it is that I need. All I know is I did this a long time ago and I opened an XML into Dons Hyperfilter, it showed me all the games, player count,controls used, genre, etc. The Mame.xml from hyperlist doesn't have all the info and I've been struggling to make an XML with all that info. I want to be able to view it in Don's and prune out the games that don't work for me, (eg. games with a spinner controller).
So I downloaded that XML from the Mame site you linked, that is what is created when you run that listxml command? So I can use that list to somehow extract the data I need into one Mame.xml file for Hyperspin?
edit: omg I figured it out.... Thank you so much for that link. In Filter Hyperlists.exe you just have to select that file as the 'mamelist.xml' and it populates all the info.
Thanks a lot
