    Default My Gen RGB out is not centered (vertical stripe on the right): Is yours too?

    I use a RGB scart out and I noticed that the screen is shifted to the left of about 5% but the most obvious sign is the vertical stripe on the right side. The stripe will be of different color depending on the background.

    None of that happen with AV and RF out.

    I just want to know if I'm the only one experiencing that. Let me know!

    Thats what happens when you use composite video as a sync signal for RGB... The thing is that the composite video is always delayed a bunch of pixels in relation to the RGB signal (because it's derived from it), thats why the cable should be using the /CSync signal instead.

    About the stripe, thats all around the display and it's normal, you don't see it on composite/RF because its offscreen, and if the cable was properly made, you wouldn't see it in RGB neither(though it depends of the TV deflection settings).

    It's called RGB shift, I have the same issue on my dreamcast :-(

    Wow, ok. Is there a way around this? BTW, I use a RGB Scart to component adapter.

    Does this affect light gun games in any way, or is it true and I "can't hit the broadside of a barn" as I keep getting told

    I have made "simple" fix for it, but it breaks 32X compatibility
    How do you do that? Any link?

    I'm thinking about building me one of these:

    It should work with all consoles outputting RGB.
    Bare Knuckle III rules! Also, the music in this game is freakin awesome.

    I simply calibrated my TV through its service menu to make all RGB games perfectly centered. Of course this shifts composite and analog TV signals, but since I hardly ever use those on my CRT TV, I don't really care. I don't think many TVs will allow you to do this though...

    Yeah... mine doesn't.

    Here's my sync shifter :

    Click for full size


    I works ONLY for MD, and it will break 32X compatibility (MD and 32X images get shifted out or roll around).

    MD/Genny, does not matter, but if the 32X is in the mix it will not work.

    Ok, well that's good. But there are a lots of things I'm not sure about in the schematics: what kind of transistors, what does the 250 kohm graph means, the ends connect where exactly... I know I need a lot of info here but, I hope someone will be willing to help.

    Thanks in advance.

    Transistors I used were 2SC945 (I love those suckers :P), and 250kohm one is a potentiometer / adjustable resistor / trimmer resistor, which you use to adjust centerness. too much/too little results in rolling+scrolling image. 150kohm is the value I recall using on my old TV.

    Can you not make the circuit toggle And where is the 1K emitter resistor going to ?

    'Why' would anybody want to pay $250 for "Digital Distribution Only" with no access to the established library of a 5 year old platform?

    It isn't backward compatible with it's own AV cables, power chargers, memory card standard, or UMD library. It only uses a proprietary USB cable for no explained reason. It doesn't even have 802.11g support, it's only 802.11b!
