Thanks a lot!
I replaced the catver.ini & the nplayers.ini I had in my Mame folder with new ones, updated the database with Mgalaxy Runway and now everything is fine
I didn't think to do so because I already had another version of these files (and it worked great with the previous version of Mgalaxy, so I thought the problem was with the new version), but anyway I have the real titles now and it's all that matters!
Thanks again for your quick reply, it's really cool to have support like this when you need it and its adding to the greatness of Mgalaxy. By the way, thanks also for your amazing work on the new version, it's fabulous!
