    Hello everyone,

    I just got my OSSC in the mail today. Judging by its configuration and setup, its going to take a while for me to get use to this device. Previously, I’ve been using the XRGB-mini Frameister for nearly two years and recently read about the OSSC. Here’s what I have:

    Sony XBR-49X700D 49″ 4K TV
    OSSC 1.6 (connected to TV via HDMI)
    6:2 SCART Matrix Switcher
    Super NES
    Sega CDX (Genesis/CD combo)
    Dreamcast (connected to OSSC via VGA Toro)
    PS2 (connected to OSSC via component cable using component switcher box)
    Gamecube (connected to OSSC via component cable using component switcher box)

    The other two consoles, Xbox 360 and PS4, are connected directly to the TV via HDMI.

    Here are some questions and issues pertaining to the OSSC:

    -I’m having an issues with the SNES. Either there is no image or the screen flickers at 5x mode. Are there any solutions to this? (I tested this using my computer monitor and it worked perfectly. No black screen or flickers)

    -On the PS1, only half of the startup sound is heard when booting up the system. Does it have anything to do with the sync drop? I want it to be like in this video

    -There is no sound in AV2 (Component, PS2, Gamecube) and AV3 (VGA, Dreamcast)

    -Just now, I noticed some discolorization on my PS2 via the component cable

    -How can I get the best possible quality on my consoles with the OSSC? Are there any console profiles for the OSSC, just like with the Framemesiter?

    Any help would be appreciated.


    SNES has been difficult with some of those newer Sony’s.
    Possibly try a trick a shmups user posted, set “Allow TVP HPLL2x” to off, then toggle between generic and optimized modes. In his case, the image stabilized (although, on that Sony, he already had stable picture at x3 and x4)

    For AV2 sound, did you toggle the switch?

    There are no profiles apart from what you program yourself. There is a list of some optimized modes in the wiki, if you’d like to try. I notice, the wiki is down at the moment…


    I turned off ‘Allow TVP HPLL2x’ and played around between generic and optimized modes. The screen still flickers, but now occurs between every 30 and 50 seconds.

    Also, I updated the firmware and I noticed there is no audio settings. There is no sound in any outputs.


    @Braca862, you probably accidentally upgraded to a firmware without audio support. Install 0.79-aud and the sound will come back.


    @megari, you’re right. I checked the bin file and it only said 0.79, no a. =/. It works now.

    EDIT: Looks like after setting Line 5x mode to 256×240 optmi., it appears that the image is stable.


    I am still getting no sound on the PS2 (and Gamecube) via component nor Dreamcast via VGA. How does the component setup actually work?


    @braca862, in order to get sound via component, you have to connect the audio to “A1 OUT/A2 IN” and have the switch set to the appropriate position. For VGA, you have to have the sound connected to “A3 IN” (the VGA connector does not have any pins for audio). The OSSC will automatically select sound from the appropriate source when you change from one input to another.


    Success! I was able to get it to work!. Turns out, I needed one one of those A/V to 3.5mm cables in order to connect the audio with the “A1 OUT/A2 IN” port. Luckily I had one spare. Now I need to see if I have another one to connect the audio for the dreamcast.


    Now that the audio issues have been taken care of, I got a couple of other questions:

    -How do I decrease the audio delay of the sync drop to 480i when the PS1 is booting up? This is one of the reasons why I switched from the frameister, since with the framemeister, the SCE logo appears just a second before the playstation logo.

    -How can I get the best possible quality on my consoles with the OSSC? Are there any settings such as brightness, saturation, and sharpness?


    The OSSC should be quite fast at syncing to the signal, so you may want to try and rule out it’s not your TV that is being slow at changing modes. It really should not take more than a fraction of a second for the OSSC itself to sync.

    As for your other question, it is quite general and really boils down to finding out the best settings for each console. The OSSC itself does not do any filtering or brightness/saturation adjustments.
