    Hi,

    There’s an ODE for the PC Engine just announced which even does more things as you’ll know by now, among them, outputting RGB signal. I’d like to know opinions since it’s a system I’m not too familiar with: how’s the PC Engine’s RGB signal when modded like this? Asking because I read that some of these mods use surface mount capacitors “for the classic jailbar fix”. Should I expect jailbars to some degree? (Talking about the original console, which I assume are all the same internally, though I’d love to know if the Core Grafx and the other non-CD family members which added composite video are different in this regard.)

    Also, seems the ODE will use a THS7374 (though not for 75 Ω impedance). Does it mean it’ll be equivalent to best mod/cable you can get for this purpose currently?

    Can you recommend me a Mega Drive 2 RGB cable which has a 470 ohm resistor for using it with a CRT TV set?

    Which power supply unit should I’ll be getting for a barebones PCE? Must it be the official one?

    Thanks for reading.

    I’ve ordered one of these so I’ll let you know my thoughts when it arrives.

    Also did I, couldn’t resist. Seems RGC will have an option for 75 Ω, so one less thing to worry about. I’m worried about the “jailbars” issue, nevertheless. apparently, you can find it whichever the console you get. Not too used with this system, myself. It seems to exist a universal fix already, but it’s not possible for me to do.

    So it seems the developers have finally cleared up how’s the device’s video output:

    Well, there is an error there in the manual. There is a 22 ohm (or 21, I can’t remenber) resistor to attenuate the output on a proper MD2 cable.

    Do you think by that that RGC’s C-sync MD2 cables will do without brightness issues (nor TTL-level ones either; the developers’ idea is that RGB TVs or scan converters should use the sync-on-composite-video modality.)? Too bad they didn’t study a bit better the video thing beforehand. Or that they actually cared. If there’s already a hardware revision planned due to stuff like this, many customers will be upset for a reason.

    They of course messed it up. Hopefully RGC releases a dedicated cable.

    Read that yours arrived and you’ve been testing it. Can you confirm you can use a regular, cheap MD2 RCA/composite video cable with the device? (Interested only in the stereo audio output with it.)

    Also, relevant link/announcement:

    No I’ve been using a retro gaming cables (non pack a punch) csync SCART with it. You have to make some adjustments to OSSC but it works when you do.

    Yeah I’ll probably sort out shipping mine back, after another few days of PC Engine fun 🙂

    Theoretically, you can use an ordinary composite video RCA cable just for the audio out, can’t you (for already RGB-modded units)?

    Of course.
