Do you use the official MAME? Or do you use a derivative or frontend?
All I do is enjoy the artwork, make suggestions, and provide the little help that I know how... it's you who does all the effort and who deserves the credit. So you should call it "Big A's Big Screen Bezels".
I do these artworks with my eyes closed, besides I won't have done the new set on my own volition without you. I might call them "Big Karnak's Big Set Of Hanger's"
So for verticle games, which type of bezel style are you going to go with? The type with no top and bottom bezel?... or the type with a very slim top and bottom bezel?
Well on first consideration, Vaughn was right to use official MAME res or STANDARD3:4, eliminating the top and bottom, it's what the MAMEDev's would have wanted. I could do mine with a small strip (not enough for logo or whatever, but enough to tie the two sides together, a Brazilian Bezel if you will.
