      Goal 4: Check if "LED"s are also supported by mame artwork in lr-mame2003 plus. E.g. Skydiver "backdrop" make use of LEDs emulating the actual leds of the cabinet.

      That would be super snazzy!

      Still if 4:3 backdrop is a requirement I think there could be a workaround: make a 4:3 backdrop with 0,0 ,1,1 coords (means covers just the game area) and create everything else of the 1080p screen with RA overlays.

      Wouldn't that workaround limit backdrops to a single resolution? I know it would be similar to overlays but backdrops are like restoring a piece of the game that has been missing from the cores. With LED support wouldn't that being the icing. Hopefully the scaling works then any monitor or TV, regardless of resolution, will be able to take advantage of them, up to max resolution you choose.

          I have a pretty strong feeling that whether it takes a year or however long there will be eventually full support for the modern name artwork format in retroarch. So in terms of investing energy over the long term I would say it's best to put everything in the frontend to that you can with the expectation that one day it will all move to the frontend and none of this will have to be in the core.

          The code that changes the color on the Invaders is located in the overlay artwork code even though it doesn't take artwork. Therefore I had to turn on overlays to get the Invaders to change colors. So for now all artwork is online even though I'd rather not have it all ๐Ÿ˜€ it's good to have the artwork fully active for the special case of Gorf too of course.

            https://github.com/libretro/mame2003-plus-libretro/pull/557

            Have you explain some where how to try this new feature ?
            I also read you have begin to add some .art to Github, it's a good idea :)
            Thanks

            Life is game, just play it !

              X-mas holidays coming so I can use both my win desktop and my Pi.

              What exactly keeps you from using both of them over the rest of the year? Just curious. ๐Ÿ˜

              Goal 1: understand the .ART artwork positioning system and make the backdrops display correctly.

              (That also applies to @markwkidd and @grant2258.)

                Amen. Agreed. The Dragon background is pretty neat though to mess around and have some fun.

                  Sure: 3:4 as it is rotated.

                    Just meant to say that lately I was traveling a lot for work. ;-)
                    During holidays I'll be able to dedicate more time.
                    I'd also like to finish part of the significant number of high res artwork I'm restoring since a while...
                    VENTURE & rare OMEGA RACE kickplate for example.

                      I agree it would limit it. As @markwkidd said it is likely we'll get full "new" artwork support in RA someday so it makes sense not to invest too much into the 'old' format.
                      For the time being personally I want to achieve correctly working backdrops with the right proportions (read: like the original cabinet); especially in SI.

                        @UDb23 - I think this looks correct. I did my calcs on a 1920x1200 monitor vs. 1920x1080 so my position line is 0,-0.66707,1,1.66585. I carried them out to the 100 thousandths. I think you need to reverse x/y values so to speak (that tripped me up a little in the instructions), basically like y/x.

                        The 0 and 1 in the position line are the top and bottom since the game and artwork match (basically a 1 to 1 ratio on the y axis).

                        The calcs take into account the game size and background only (not the display) as a decimal ratio from 0 to 1. It seems like it should scale down on like a 720p TV or up.

                        The black bar at the bottom and overlay clipping are only in the screenshot and they look fine on the Pi. I was using RA for screenshots and it's clipping them for some reason. Should the background be showing through? That does actually show in the game.

                          @Riverstorm You nailed it !! Well done.

                          Should the background be showing through? That does actually show in the game.

                          No, it should not.

                            I just re-checked; basically it seems you can't set the opacity of the SCREEN layer (actual game graphics) . The SCREEN opacity should be 100% by default.
                            @markwkidd, @grant2258 : could you check the code part that does the blending ?

                              @UDb23 @markwkidd : looking at @Riverstorm's screen capture it looks like actually only the green graphics are partially transparent; white looks correct (100% opacity).
                              Maybe it's related to the code you wrote to add the green color ?

                                  @Riverstorm is this doing the same thing on advancemame for you or is it a regression on our part

                                    well the colors are not set by the artwork files, The are set by the driver as soon as you enable the artwork system the colors will appear in the game.

                                    https://github.com/libretro/mame2003-plus-libretro/blob/644b581886abe9b9272cf8027088754b31583ac2/src/vidhrdw/8080bw_vidhrdw.c#L55-L59

                                    i think some kind of masking will be needed

                                        @UDb23 - Here's the correct position for a 1080p TV. 0,-0.57142,1,1.57142. I've been working with a monitor the past few days so I did the original numbers with that to verify and then redid them for 1080p. For numbers I used 1920x1080 and 896x1080.

                                        @grant2258 - To test just update from source?

                                          alpha = 0.3
                                          to the backdrop

                                            @grant2258 If it works that way, we are all happy.
                                            From a logic point of view it doesnโ€™t make any sense as that alpha (according to mame docs) should be the transparency of that layer. In this case sets the backdrop transparency to 30 percent ?!! There is nothing below the backdrop.... but it makes the games screen on top 100 percent visible ... weird.

                                            Anyway, as said, if thatโ€™s the solution weโ€™re glad you found it and will use that settings.

                                            Once we finish all this testing it makes sense to summarize the findings in a specific doc/wiki.
