Ok guys, so I made a PHP script that takes the XML output from the newer mame and the Catver.ini file and creates the .lst and .ini files for Mamewah, based on all the different categories. It first takes the games not found in the Catver.ini and puts them in the No Category group, then takes the foreign languages and puts them in their own group, then goes through the rest of the games and puts them in the categories that they match. My question is: would anyone else want this? I just made it for myself, but if someone else wants to look at it and use it I'm more than happy to send it their way. And if someone else out there does this, then nevermind
