    Hello everyone!
    I plan to buy a Keico OSSC.
    But I have a little doubt for my Megardive 1 Pal (and same idea for my Neo Geo AES jap):
    The audio scart signal is limited to mono. But the consoles have jack stereo output.
    Did I need to buy retrogamnig scart cables for taking this stereo output into the scart, or can I can put the scart on AV1 AND the stereo audio on AV1 or AV2 (with a separate jack to jack cable)?

    Thanks a lot in advance.

    Best regards.


    It’s not currently possible to select alternative audio source for AV1. So you need a cable that connects the headphone jack out of your consoles to the audio pins on the scart head. You can probably mod your existing cable yourself quite easily (just make sure you disconnect the mono audio source!).

    If you would like the functionality you suggest in FW (if I understood correctly, make AV2 audio input source selectable together with AV1 video source), you can make a post in the features request section. I’m not sure there’s some technical limitation to implement this feature, since it could be expected this would have been implemented already.


    That was I thought. Thanks a lot for the information.
    Well, selectable audio can be a good thing if possible (and/or for the pro version 😉
    I think I can’t wait the pro and buy the Keico now ? … and the scart cables … if answer me about the availability of the Neo Aes sacart+jack stereo cable …
    Have a nice day


    How about buying one of ours since you got help here on our forum? 🙂
