Yes, my settings on my bartop cab (MAME v.100) look like Jim's (easy, easy, easy), with no DIP switch diagram. I tried to adjust them to match what you guys are seeing (normal, fast, normal) but the wording is different. So I bumped up the first and last setting (medium, easy, medium) and tried a game... definitely more difficult.
I'm going to try to get the Japanese rom running on this old mame like Waki suggested and check the d/p settings. It seems like "medium, easy, medium" settings on old MAME versions/xbox match up with "normal, fast, normal" settings on later MAME versions just from playing a few games on each.
My suggestion is that we use either "easy, easy, easy" / "few, fast, slow" OR "medium, easy, medium" / "normal, fast, normal" depending on the kind of punishment we wish for.
Of course, Waki and yama will probably find a way to roll over the score or break the game while channeling D.A.R.Y.L.
