mame is open source as is while it does have its rules theres nothing in it about posting a patch since a patch is a option to the user to use it or not. don't know about you but i've seen plenty of mames that have banned games and such which you can find easily by a google, so i doubt that will stop a thing you might've notice gogo now does this with his fba-xxx releases. kawa-x is dead due to the fact the project is no longer in the makers hands since he got tired of it and passed it on to razzola which doesn't even own an xbox nor is he willing to continue kawa-x for xbox. as for fba, well there still hasn't been an update for the pc version so untill that happens, i doubt you'll see another update as is
