I recently configured M2 and CPS3. They run perfectly outside of Maximus Arcade, but do not have sound once I run them inside MA (and yes, I have the "Enable Sound" option checked). Also, when I press certain keys (seemingly only letter or number keys), I receive that Windows error "ding" sound. Once again, this only happens when I run these emus inside MA. To remedy this problem, I needed to disable the error "ding" sound in the XP Control Panel. However, I do not understand why I would get that sound in the first place. Any ideas?? I would really love to play these games in MA with sound. Thanks.
