      <p style=”text-align: center;”> I purchased a TEDdidgitizer from copperdragon so i can use lumacode with my OSSC Pro however I can not get the image usuable. my C64 lumacode and vic20 lumacode are beautiful so can anybody tell me the settings needed for my c16 please? I reached out to copperdragon but he dosnt have a OSSC Pro and told me to try using the lumacode mode for atari7800 and that hasnt made much dofference either.</p>

        Hi,

        C16 version of Lumacode was not finished when the OSSC decoding part was completed so there’s no a readymade preset yet. You could however edit Atari 7800 LC sampling preset and set H. samplerate to 342 as the first step. Apparently the board utilizes minimal sync and backporch so next you need to tune down those too on OSSC side, and also probably reduce Clamp position and width into half from video opt. menu. Together with the usual phase adjustment that should give stable (but incorrect) colors, so the last step is to load a proper palette. Below are links to test PAL and NTSC palettes for C16 to be used in 7800 mode.

        PAL
        NTSC

          any ideas of the sync and backporch numbers needed?

            You can just use the position adjustment function to minimize H. backporch which should be sufficient.

                <p style=”text-align: left;”>I feel like lumacode on the ossc pro is seen as an afterthaught are there any plans to add more computers to it and to make it easier to use?</p>

                  Here’s a link to a profile that should be preconfigured for PAL C16 Lumacode aside from sampling phase adjustment. Presets for Lumacode systems besides the currently supported ones (all except C16 for now) can be added on the firmware only after someone with the respective HW has tested it out, i.e. basically what we’re doing right now.
