For anyone trying to find a solution to this that comes across this thread, the controls are ORed in the code in many of the cores of the older games and would require those trying to put this in a cocktail cabinet to unOR them in the code. I found this to be true of most of the cores that would have had a cocktail cabinet option.
Hope that helps.
FYI, for anyone finding this, I dug into this core and it seems it was hard coded for upright. When I hardcode to cocktail the video doesn’t rotate correctly for player 2 so that might be why it was hard coded for upright. Not sure I have the capability to fix the video, but I thought I would post what I found.
Was a solution ever found for this?
Is there access to the code to un’OR’ the inputs.
Did original hardware have the inputs ORed for cocktail cabinets?
I think ORed inputs in cocktail cabinets in original hardware would have led to a lot of hard feelings.
I hope this is the right place to post, as I’m new here. I’m trying to update my cocktail cabinet to a MiSTer. I can’t seem to find a way to put dig dug into cocktail mode. Does this capability exist?
