I am sorry for the million questions..copied from my post on a different forum.. And close to a separate post I made earlier...kind of botched that so starting fresh with better info. I have tried to search the retropie forum, ArPiCade and KLOV as well. Not finding my answer.
Dylan (ArPiCade creator...awesome product by the way!) has this set up displaying horizontal games in AdvMame stretched accross the full screen. (Which is what I am trying to achieve) In my AdvMame on retropie I can not accomplish this.
Is this an overscan setting? If so, wont that affect how all games are displayed? Meaning it would then distort the vertical games that display correctly.
Im thinking its not "overscan" because within the rpicade's advmame game tab >video>modes selections I have different Option settings than in my other Raspi3 running advmame in Retropie.
Is there a way to go into AdvMame and change these? Please advise. Thanks.
Again, I apologize if this is not the place for this...but you all seem the most versed in these things.
