    Hello,

    When I’m connecting a Genesis to the OSSC the video output are like this:

    If I set the OSSC to use Generic 4:3 on 5X it gets more clearer but still flickery.

    Before this I got problem to just get sync, but that was solved by max out Analog sync Vth (349mV).

    The cable I got looks like this:

    Any suggestions?
    Can this be solved by buying “The latest” version of Megadrive cable from RGC?

    That is super noisy. It may be your Genesis needs some TLC. What model is it (model 1?) any RGB upgrades (bypass board etc?). Have you tried another power supply (for the Genesis) ?

    Its a Model 1. The seller says it works good on CRT, I have no reason to doubt him on this part.

    What is TLC?

    I bought it pre-modded with RGB Amp and Mega Amp 2.0 installed.

    This is what it’s look like when I set it too Generic 4:3.

    I’ve tested to set coast-values to 3.

    Regarding the cable, It came with a 180 Ohm resisitor I think. Could make a difference to have a 470ohm instead?
