          @grant2258 That was fast. Thanks! Audio sounds good. It is weird how the intro part of each level has this severe slowdown but the rest of the game is fine at 60fps. At 1.5Ghz, with FBA i get 60fps at the intro part but then it's the rest of the game that's slow in the mid 50s.

              @grant2258 @Darksavior May I ask you guys at what resolution you play and if you do any shader? Both are affecting the fps too.

                  @darksavior How do you determine the fps? I want to see how much I get with 480p and scanline only shader. Just for curiousity.

                    @thelostsoul You turn it on from the rgui by pressing hotkey+x. They changed the area where it was. I forget where. Onscreen overlay options or something.

                    Scanlines are achieved by an overlay which is just a picture with lines (yuck) and doesn't affect performance. Or by a crt shader like the optimized crt-pi shader or zfast shader which produces a crt tv's dots and properly produces the scanlines. The PC version of retroarch has more advanced crt shaders that benefit from a 4k tv.

                    You can also tinker with the shader settings. I don't like the crt-pi shader's default. Too dark. I max out the shader's brightness setting and use that.

                      @darksavior Ah ok, I just thought there would be a different way to do this properly. I remember that option now you mention it. About the shaders, I like the crt-pi shader and its vertical counter part, but 1. they aren't made for 480p 4:3: pc monitor and second for some arcade games it just looks awful. And I read somewhere even the crt-pi can have an inpug lag effect on "some" systems, but probably even not noticeable.

                      Anyway, thats a different story and probably this isn't the right place for talking about it. I will test some games and check the fps.

                        Tatsuya79 from the libretro team says that the very latest RetroArch nightlies/source provide improved mame2003-plus runahead lag reduction via the "2nd Instance" approach.

                        It remains to be seen whether that will be practical on low power systems but there are examples of runahead working with some other cores on the rpi -- it is likely to vary from one game driver to another with this core.

                          What is the "2nd Instance" approach?

                            That's a setting in the RetroArch latency settings -- it should be enabled for mame2003-plus runahead.

                              @markwkidd - Ok, I see why that could be resource intensive but it would be slick if it works well on the Pi. I wonder what console cores are using it. Here's a Libretro link that explains what it is and how to use it.

                                There are some posts in these forums you can probably search out -- my sense of the state of runahead on pi is that it's limited but better than many were initially predicting considering the pi cpu.

                                  The RetroArch developers have said they will add support for MAME artwork files to RetroArch (including backdrops and bezels) if someone will code it.

                                  I've started a bounty for anyone interested: https://github.com/libretro/RetroArch/issues/7419

                                  This would be a great step forward for all arcade emulation via RetroArch if it is added.

                                    This would be absolutely great !

                                    Actually full Mame .LAY format implementation is probably not that easy as it involves not only overlays and backdrops but also LED implementation, bezels and buttons.

                                    Getting just backdrop support as you proposed (possibly with same .cfg settings approach as currently for LR overlays) would be enough.

                                        Added to bounty. I think it would be great to see backdrop support. I know you guys have made some fantastic ones that I would love to see implemented with the bezels. That alone is pretty exciting and further consolidating to one emulator as I use AdvMAME for backdrops now even though they aren't very good.

                                          Have you seen this ? Advmame 3.9 has a new function to manage overlays and backdrops in better quality but it also seems this slowdowns roms significantly on the Pi.

                                            @UDb23 - Nice, I had not seen that one. I'll do some testing once it's released on the Pi too.
