This is something that has befuddled me for a while now.
For whatever reason, MAME (to me at least) seems blurry by default.
I've noticed it in the text screens (press OK to begin) as well as in gameplay.
In MAME32, if I uncheck "stretch using hardware", this seems to do the trick. I then add scanlines, and everthing is to my liking.
This "blur" thing seems to be fairly new as I don't remember it in old versions of Mame. As I remember, they were always clear.
Can anyone shed some light...........?
