      Hi marqs,

      Just flashed 0.90 to test and I get a very flickery/jittery image seemingly regardless of output modes and settings, though some are better than others.  This is feeding into a Tink 4K’s HDMI input.

        Assuming the TX Mode setting is the right one to change, there was no difference in DVI or YCbCr444 mode. Haven’t had a chance to try out any older firmware builds yet.

          I finally tracked down some old shmups posts about the alternative firmware- it was related to fitter seeds used at compile time.

          https://shmups.system11.org/viewtopic.php?p=1378441#p1378441

          Those small flickering pixels are the kind of thing I’m seeing- not awful or anything, but definitely annoying when they crop up.

          Marqs, would it be possible to recompile the latest firmware with an alternate seed if that’s easy enough to do? Maybe it’s a crapshoot and I’m misunderstanding though. In the meantime I will try some older firmware versions and see if I can get one that works better.

            Hmm, I was using a powered HDMI splitter, which was the first thing I got rid of to make sure. But I’m straight to the TV (LG B9 OLED) now, and tried with different cables, including my nice HDMI 2.1 certified one that works with my PC at 4K 120Hz 10 bit color, so absolutely overkill.

              I thought I’d check the VGP forum for an official topic on this.

              Do people really dislike the OSSC’s 480px2 scaling that much? Even with upsample x2 enabled? I hate how 480p looks on my HDTV, I want it much sharper- exactly what the OSSC can offer (with from what I understand a middle-ground sharpness with upsampling as well).

              The added value is incredibly obvious to me- full digital signal path for HDMI mods that output 480p max. That’s Gamecube, Wii, and surely more in the future. A little future-proofing goes a long way.

              And as someone said that HDMI mod creators should instead implement upscaling for their mods- why raise the cost and complexity of every single HDMI mod when you could instead do all the upscaling with a single device that a lot of people doing these console mods are already going to own?

              Plus, I’ve already invested a lot of money in a GCVideo modded Gamecube- if the project switches to a larger FPGA that can upscale I’m looking at a cost similar to a new OSSC anyway to completely redo the mod. I’m sure others would feel the same way.
