First, is there a way to customize the FBA frontend? There's an option called 'external skin', but I don't know what it's for nor how to use it.
Second, although Neogeo games run perfecly smooth with FBA, I've noticed some minimal interruptions in sound every now and then. What's the problem and how could be fixed?
Finally, I've noticed FBA has a file called default.cfg, which can be downloaded and edited. That's great, because that way I can set vsync on and fps on, for all games at once. MAME also has a default.cfg file, as well as .cfg files for every game. However, after downloading them, I see they are binary, not ascii, like in FBA. I'd really like to make permanent settins of some options per game, such as gamma. Any way to do this?
