I actually don't like the emulated sound in DK. It's really bass-heavy. However, I like the color rendering. And it seems to play differently - perhaps more unpredictable. I generally play on .104 . However, for vectors, I've found .69 is best. They're really defined, like in newer mame, but still have sparkly stars and stuff. (For some reason, the directdraw rendering in mame changed after .69 or something, so the vector lines are not as defined.) Of course, I don't really care about the newer SF and X-men games that are available after .104 . Oh, and for my main game-playing I use Advancemame, and .104 seems to best version.
