-Were the other ones updated? They look to be the same as the old lay files. Fire is updated.
-Random note, the screen width on Donkey Kong Jr. looks to be off in the Unit and Background views.
-I had to look hard but I see the issue you mentioned on the Crystal Screen games. Well, Climber at least. I can't get Balloon Fight to work with the new ROM's posted. Oh, well. I did have a thought. What about cutting holes in DR-802? You could have a standard DR-802 as the bottom layer, and the cut version as the top. Then when the button is pressed you can have the "down" button appear in between.
