Try Sonic. Just run around in the waterfall. You'll see it.
I have a non-TMSS system, and I haven't seen it either.
I am interested in this phenomenon and the theory that it is caused by bad capacitors. Has anybody replaced the caps on a system with the problem and seen it go away, or is it all just theory?
I am going to replace all of the caps on my system as a preventative measure. If anybody has a system exhibiting the rainbow banding, I will replace the caps for free if you will make an article about the subject with before and after pictures. You would just have to pay shipping both ways.
You're both DEAD wrong-- rainbow banding is when the Genesis declares to you:
"I'm gay and in your face!" and then it's pretty much marches, parades and leather pants.
Jeez, I'm tired.
I thought it involved a bunch of girls with different shades of lipstick...
anyone have a picture of what it looks like ?
You can see it in some youtube videos, I can't remember any specifically (but I know soem of mn12birds and CGR HD have it, I think MN12bird's Comix zone review shows it -especially at the boot/title sequence). There was a shinobi 3 video which showed it really well too.
Anyway, it's basicly thick vertical bands of iridecent colors, each around a 1/12 the width of the screen I think, and most visible on black screens and waterfalls (and similar) in the BG, the tubes in chemical plant zone show it quite clearly.
Edit: here at ~0:36 I think http://www.youtube.com/watch?v=oCDoP-zwoVI
I think s-video modding may eliminate it, and it's absent form RGB alltogether. I think the composite vs s-video vs RGB comparison TmEE posted recently shows the ranbow banding in composite, but it's not very clear.
The CXA1145 and 1645 encoders (the latter only on late model 2s and all model 3s) do have their own vertical banding tendancy, but shouldn't be visible in composite, and more like pin stripes (as on the NES -on a TV with really good comb filter- and famiclones), though I think those might be more broadly spaced than on the NES if that's what I can see on my TV. (which shows the NES's lines as well) They're very visible in s-video if a sufficient resistor (I think ~480 ohms) is not connected to the chrma line.

Look at the "Enemy" life bar.
ok that's good to know my genesis doesn't look like that
Behold - rainbow banding, albeit a bit extreme :

ok my genesis is not like that at all and it was made in 1991
The bottom one is RGB?Quote:

Mine are probably from 1990 or 1989, so go figure. (I think the ones using the cheap caps may have been more common in the early models)Quote:

Off topic, TmEE, what kind of TV is this that can display full border areas :?:
On that note, see how the vertical borders does not start and end at screen boundaries. Do you have any idea why ?
Both are composite.Quote:
