      Hi,

      I noticed some ugly flickring here in some GBA games.

      That flickering is supposed to even burn into some N3DS Screens as I read on gbatemp.

      On PC (VisualBoyAdvance emulator) I can simply chose "Interframe Blending" - "Smart" and it is transparent.

      Does retropie have a solution for that, too?

      I couldn't find it and would really appreciate your help.

      Best wishes!

        I don't believe that option exists in lr-vba-next. Have you checked to see if the flickering exists in the other GBA emulators?

          I have only gpsp and lr-gpsp to choose from (which are basically the same I guess) because I run retropie on pi zero.

            They are actually completely different emulators with different development histories. The issue at hand may be universal, but it would be worth testing to find out.

              on my pi0 I only have those two emus to choose from (gpsp and lr-gpsp) and it is the same on both unfortunately.
              on PC it is no problem to choose a filter that blurs the images.
              since the filter folder is empty on my pi0 retropie I thought I could get that "smart interframe blur" or something from a rpi2/3 retropie and put it there as a filter. would that work?

                For what it's worth I tried it using mGBA on my Pi 3 and it also has that same track map flickering.

                  @ obsidianspider:

                  thanks for trying that out. Can you go to core options and select a video filter that prevents that?

                    @naddel81 I run my Pi without shaders, but I went into Video > Video Filter and it was set to N/A and when I selected it I got an empty directory.

                      OK, thanks. Guess I have to live with the flickering then :( Hope my screen survives it.

                        This almost has to be isolated to specialty screens. In most cases an intermittent image only helps to prevent burn-in. Granted, it's a bug and some sort of fix would be ideal, but I have to wonder if this issue would produce any screen damage to conventional displays.
