    • MVS weird pixel issues

      I bought the multi MVS on the first batch from @CPZ - SAVEYOURGAMES but only recently I got some free time to play some games.
      While I was playing I've noticed some weird pixel on the menu background and in the energy bar of SVC chaos that has a strange interference that I've never experienced using the 161 in 1.
      I've asked to @Darksoft before posting but he never experienced that behaviour.
      anyone has experienced this issues?

      I've tried with:
      MVS-1C with Multibios 3.3
      MVS-1ACH with original bios
      using:
      Arcade PSU+HAS --> Hydra Switch --> Shinybow scart amplifier ---> OSSC+VP50 ---> SAMSUNG LCD
      Arcade PSU+HAS --> Hydra Switch --> Shinybow scart amplifier ---> XRGB MINI ---> SAMSUNG LCD
      Arcade PSU+HAS --> Hydra Switch --> Shinybow scart amplifier ---> BVM-20F1E
      Arcade PSU+HAS --> Hydra Switch --> Shinybow scart amplifier ---> PVM-20L2MD

    • If it can be helpful I just saw a video on YouTube of a SVC chaos gameplay with similar energy bar's behaviour (this one is less blurry that in my case):


      unfortunately most videos have a "normal" energy bar..
      Like this:


      Anyway those video are quite useless for my issues as it's not clear if they are played using original hw/cartridge or not.

      I've searched a lot for photos of the menu in the forum but I didn't see my same issue anywhere..

      To be clear I'm not that kind of perfectionist that wants everything perfect (well I'm quite like that xD). If the weird pixels on the screen don't cause any problems with games in general I can live with that.
      My only worry is that my multi can get worse with time or have problems in some games..

      It's for sure strange, is it only that one game? Or have you noticed others with random/strange pixels?
      I played 5 or 6 other games but didn't noticed anything in particular (or at least so evident like I'm SVC chaos) just some weird pixels (3 or five) appearing near the score in magician lord when you die.

      Anyway I'll do further tests as soon as possible

      Tbh I'm 100% sure it's related to your setup as the cart does the same with NeoSD.

      @sk8er000 can you please remind us what video adapter and Monitor/LCD are you using?

    • Can you remove the Shinybow scart amplifier from the equation? Why is this component even necessary?

      Seems more like a video processing issue to me. You have a lot of devices in your chain, better to keep things simple and minimal.

      Also, try enabling / disabling the HD mode of the Hydra.

      I use the amplifier because I need to have 3 outputs for each standard (scart, component, svideo and VGA), one for ossc, one for xrgb mini and one for CRTs.
      Since I use a lot of scart devices (consoles+retropcs+supergun) I had to switch from a shinybow 6x2 to an hydra 15 plus gscartsw, for the other standards I use siwitches with already multiple outputs.
      Anyway when I'll come back from work I'll try a direct connection with each output bypassing every switch or amplifier.
      This setup never gave me problems and the behaviour with the 161in1 is different using the sane chain. For that reason according to me is strange that this is a setup issue

      That's the reason why I didn't publish the videos on YouTube I don't want to discredit @Darksoft 's multi in any way, I just want to understand what's happening :)

      SNK VS Capcom acts the same on my mame setup, the pixellated change of resolution of the bar is in the game
      That's the kind of info that I was hoping to read about SVC Chaos, so maybe it's a normal thing..
      I've tried with a direct connection with every source (ossc alone, xrgb mini, and CRTs) and same behaviour. I've also tried a different LCD and recording a short video using the X-Capture mini and same behaviour.
