Got an official RGB scart for Xbox - yeah definite upgrade for sure.
Unless I'm missing a something, a small annoyance has been introduced to the 0.76 firmware. The selected input resets to AV1 RGBS (button 1) every time you power back on. I'm using the OSSC with a Wii so I have to manually select AV2 YpPbPr (button 2). This setting doesn't save/load with the profile.
On a related note, it occurred to me that line-doubled 480p games should have scanlines enabled. I've had a mental lapse in thinking having them on is erasing half the picture information, but no, that's silly. I'm only erasing the doubled lines that cause huge, unnatural jaggies. At exactly 960p, the lines are very thin: bad for 240p content, but perfect for 480p. The effect looks identical to the thin scanlines of a 480p/HD CRT and creates depth and natural AA. It also masks the Wii's blurriness and artifacts (ditto for 240p games in Line5X). This may become my new favorite way to play Wii games.

Consider moding if you haven't already to remove the filter and really get more bang for you buck.
Oh, got a link?
For moding or removing the filter? Unfortunately I have neither on hand. This stuff is burried in derelict websites from the early 2000's and my own "tools" are burried in boxes from a move I did in October.
It doesn't look like removing every odd line, but more like merging them together and adding thin black space between every pair. It doesn't remove information either way but it results in much thicker scan lines so that it doesn't mess up the picture completely.
I tried removing every odd line on a 21" computer CRT to make a 200p line-doubled image look like "pure" 200p at a 400p resolution, but the resulting visible scan lines were so thin and probably accentuated the flickering, giving me a headache.
Interesting, though I still have some reservation, mainly due to some questions I still have about line multipliers feeding into scalers. After a multiplier does its job and sends the doubled up vertically image to the TV or scaler, I assume its up the scaler to get the correct width of the frame back by scaling horizontaly according to the aspect ratio you've chosen? So do we end up with doubling vertically and interpolation horizontally for correct aspect ratio?

New revisions of the N64, PC-E/DUO and SNES RGB boards will be added to the store very shortly. Sorry for the delay, #HIDEFNES is a killer..
Information on removing it, if possible. If not I'm sure I could rustle something up via Google.
It does remove every other line. It may not seem that way because I compromised and set scanlines to 31%. If you do 100% black, it gives an ugly muted picture that can only be fixed by significantly boosting brightness and color saturation on the display. I'm not doing that because I'd have to keep changing it back for regular TV and video games. I prefer partially dark lines anyway... looks a little more natural and sort of mimics the variable width, blending and glow of real lines on some CRTs. This is the closest I've gotten to the 480p CRT look on my HDTV.

Monitor's fault? That's unfortunate. I've gotten good 200p CRT results on the MiST and DOSBox (400p with scanline filter). Aesthetically no different than scanlines on native 240p games.
The OSSC also handles horizontal size to be in proportion with the line doubling. I don't know if the process is literally horizontal doubling so I won't call it that, but that's effectively it. And with some settings (240p Line 3/4/5x), you can adjust the aspect ratio, so that NES 254x240 comes out to 320x240 times whatever line multiplication you selected.
My experience with this is limited to the Wii, but there it's not an issue. The console is SD but it was made to play on widescreen HDTVs. Set it 16:9 mode, you get a 720x480 output with in-game graphics that will always scale to the correct proportions when blow up to the full horizontal and vertical size of a typical HDTV. This includes with our without the OSSC.
As you know I have the additional scaler hardware to maintain the exact line-doubled output: 1440x960 in a 1080p frame. This is the exact 4:3 aspect ratio. I have to play at Wii's 4:3 menu setting because at the 16:9 setting I have no way of doing a 1.18x horizontal scale to correct the skinny proportions: 720x480 -> 1.185x H scale -> 853x480, the correct proportions. Same as if the Hi-Def NES mod was lacking the Horizontal scale feature to fix the 4x/5x scaled 256x240 raw output. I don't mind... 4:3 mode is sharper and has less artifacts.
There's an option in UnleashX (and I assume other dashboards) options somewhere to turn off the flicker filter and other junk.

My Xbox is stock.
You need to mod that Xbox, I did to mine and it was worth it!My Xbox is stock.
Well, let's hope the disc drive is good, because that console does have bad disc drives that fails to read games that are clean even.I dabbled in modding the original Xbox well over a decade ago. Playing games from a HDD is sweet but I'm happy with my 1.0 box being completely stock now, I don't use it for anything beyond playing my retail discs anyway.
So in essence, given a perfect integer maping and if the OSSC is doubling on both axes on the screen, you are getting: 1 pixel from frame = 4 pixels on screen? So wouldn't adding scanlines sorta ruin that interpretation of a 4:1 pixel? Cuz it seems you're re ending up with a vertically segmented and horizontally stretched image like this, and in a sense, are cutting off the new 4x pixel.
The monitor may simply too high res for this sort of resolution (its max res is 2048x1536). Here is what I get with winuae in 512x384 fullscreen, with the scan line filter or line doubled like a DOS game.
The scanlines are even thinner in reality, I suppose the exposure makes them thicker or something. I know nothing about photography.
And while I may get used to it in games, using Workbench and reading stuff is just painful. I'm pretty sure using a real Amiga on a TV would be a much better experience than scanlined on a VGA CRT. Or I need to get the old 14" from the attic, which would probably be better suited for such low resolution.
Right or wrong, here's what I observed:
One would think so, but it visually doesn't work out that way. The lines are thin and the eyes just fill in the gap, minus large jaggy steps from not using scanlines. If this did look wrong, I wouldn't have bothered.
I think it's the same principle as with a 3x (720p) NES upscale. Every pixel blows up to 3x3 pixels. Add a black line to one of the pixel rows and you won't have square pixels; each pixel becomes 3 wide x 2 tall... or even 3x1 if you want BVM-like black lines. Same uneven split for 5x NES upscale, which looks awesome. It doesn't skew the image due to what I guess is our eyes' ability to fill in the missing information. I *think* Wii pixels are also supposed to be slightly wide but I'm not sure this plays any role.
I think those look fine, similar to the pic I posted if you view the full size version, unless your pic really is misrepresentative of the line quality like you said.
I think I'm gonna go ahead and disagree that doubled 480p should have scan lines. I think adding scan lines is mabe too much of an alteration. It might add some smoothing but you're changing the brightness and color range of the overall image. In contrast, a 240p game mught have compensated for it. I mean sure, when you blow up an image, it looks more jagged, but doesn't this principal also apply to 480i CRTs of various sizes? I think increassing the size of a roster should have expected consequences, which I can live with.
Maybe "should" was too strong a statement. But I've always said 480p games on my HD CRT have visible black lines and that's on a smallish 17" screen. They're in every 480p photo I've posted over the past year. Turning on the OSSC scanline filter brings the games closer to how they look on that CRT. It's plainly more like the CRT PQ than raw output.

All games with full scanline filters on a HDTV have some reduction in brightness and color that alter the picture. That includes 240p games: the Ultra HDMI N64 mod has scanlines but they make games very dark, therefore it has a gamma boost feature to compensate. Even so, the full blacklines filter is too much (a partial transparent filter works better).
Here's a closer look. Disregard slightly different "e" proportions of the CRT version... I took the pic at a different angle months ago.

The OSSC also handles horizontal size to be in proportion with the line doubling. I don't know if the process is literally horizontal doubling so I won't call it that, but that's effectively it. And with some settings (240p Line 3/4/5x), you can adjust the aspect ratio, so that NES 254x240 comes out to 320x240 times whatever line multiplication you selected.
Ok, disregard my complaint above, I didn't try setting the default input. I'm sure that's what I did the first time around when I got the OSSC and simply forgot this time. Thanks for the tip.

All those upscalers are too rich for my blood. I just picked up a 27" JVC D series for 30 bucks. I'm using S-video and it doesn't look half bad.

I'm late but I wanted to add something here.
I'm not aware of the exact sample rate used by the OSSC but the standard for 240p/480i is 720 samples per analog line. This does not mean that 256 pixels the NES/SNES/others output gets scaled to 320 and then scaled to 720.
I really think the best thing is to assume once anything hits an analog wire, you no longer have pixels. You had 256 pixles but they have been output to (appx) standard NTSC timing to fill a 4:3 frame. Since we're digitizing it, we just take 720 samples of that line, giving us (except in cases of garbage implementation) a "perfect horizontal scale" (literally resampled) at 720 samples.
You never have "320x240" from a 256x240 console, excluding some horrific implementation.
For 240p you get 720 samples of each line with 240 lines. For 480p you get the same 720 samples of each line with each line duplicated for 480 lines (unless the OSSC is using the 640x480 mode, I guess). For the other higher modes you would either have 720 pixel line resampled digitally or you would sample at a different rate to account for the output at those resolutions.

The most important thing is your own personal enjoyment. A friend of mine has an RGB monitor and cables for their setup but still takes time to play some things in composite just for the nostalgia.
Nice! I gamed the ps2/xbox gen on that TV (silver 27" via s-video too).
i need to join this waiting list for OSSC
edit: just signed up
If you signed up because of the recent conversation, just be aware that mega is using additional hardware to achieve a perfect pixel map of various integers on his plasma. The OSSC may also not play nicely in all modes with your TV.
