Up to you, really. The fix is pretty easy (and cheap) if you have a soldering iron, but, as you probably read, it’s also not perfect since it causes some minor issues in certain games. I’ve been quite happy with the results, though. Using a non-1-chip system with the reverse LPF on the OSSC might also be a good compromise. The Super NT has had most of the kinks worked out at this point, I think, so it’s also a good choice.
It’s normal for 1chip systems. There was a whole thread over on Shmups about it, but you can read a summary and see the fix here: https://retromods.game.blog/snes-sfc/snes-1-chip-ghosting-fix/.
Yes, the test pattern displays until an input is detected even with autodetect. However, I will note that I don’t think the OSSC actually turns the output “off” in that when I connected it (and other things) to an HDMI auto switcher, as long as the OSSC is on (even with it outputting “no signal”), it always stays on that input. So it may still be outputting voltage or something, not sure.
Sound always comes out HDMI AFAIK. The toggle controls whether the 1/8″ jack is used for input or output. If you have audio downsampling turned off on the OSSC, try turning it on. I get glitchy audio with the HD60 Pro unless I have that on.
Seen many comments here that the Elgato HD60 Pro does not play nice with the OSSC, but I tested it yesterday and I’m not having any issues. I use line5x with the 1600×1200 setting and generic 4:3 and it’s working great. I tested with NES, SNES, and Genesis and no issues with any of them. Keep in mind that I have dejitter mods in the NES and SNES and a sync stripper in the cable for the Genesis, but the point is that with clean sync these all work. I did have to enable downsampling for the audio to get the audio to work right, though. I haven’t tested line2x or line3x yet.
Does it work with other consoles? NES and SNES generally need dejitter mods to have stable sync. Many TVs will not recognize signal from them at all through an OSSC, so I suspect capture cards will also struggle. Even then, OSSC does not have standardized output, so you may still not get anything. There’s a thread here somewhere on capture card compatibility that you may want to dig through.
It looks better with the TV scaling because the N64 looks horrible and blocking. What you are seeing with the OSSC is more accurate to what the N64 is actually outputting. Some people like that, others (like yourself) find it to look quite horrible. Nearly all early 3D systems look pretty bad when scaled this way. The TV, as mentioned above, has a proper scaler that can interpolate the pixels instead of just doubling/tripling/etc them. This allows it to make the image look smoother and less blocky, but at the cost of additional input lag.
This is easy to replicate in Photoshop, as shown in this image: http://www.chrismadden.co.uk/inkline-press/create/create3/figs/6-18.html. Nearest neighbor is the rough equivalent of what the OSSC does. It provides very sharp lines, but a blocky image overall. The others look somewhat blurry up close, but when you back out, what you actually see are smoother lines.
– While I’ve read that composite and S-Video can output 240p, I thought that the only way to get a progressive output from the Dreamcast was through a VGA box. When I read about it, people were talking about VGA Boxes so that’s why I assumed it only worked that way. I’m probably wrong, so don’t quote me on that.
240p is just a “hack” of sorts for 480i. 480i is basically 240 lines at 60 Hz, but every other set of 240 lines alternates its location so that it appears to our eyes like one 480 line image. 240p just uses the same location for every frame instead of alternating, so you get a 60 Hz progressive image but with scanlines.
In regards to the Dreamcast, what people are talking about is 480p. Composite and s-video are not capable of sending 480p, so you will need a VGA box to do that. SCART can also carry 480p, as previously discussed. All of these connections are capable of carrying 480i and, by extension, 240p (since it’s just a “hack” of 480i). However, as you mentioned, most Dreamcast games don’t support 240p specifically, so you are generally only getting 480i or 480p, the latter of which requires the box.
All of the USB 3 capture cards have very specific USB chipset requirements, too. Make sure that the brand of USB used on your computer matches the requirements or you will get nothing but trouble.
I guess if we are talking about officially supported signals, then yeah, only 480i over SCART. But is there an official box that has a SCART output anyway?
Some notes on your notes. SCART can also transmit 480p as I mentioned above. That plus the ease of configuration on the OSSC side is the main reason I recommend it.
Regarding RF output, the NES still had an external box thing, but it also had a modulator internally. Not really sure why it had both, but it did… PCE/TG16 also had internal modulators. But even as recent as the original Xbox had options for getting RF if you really wanted it.
Regarding region lock, I know that you can play JP games on a US console by way of a boot disc. Not sure about PAL and NTSC, though.
The other benefit of running the Dreamcast into the SCART input of the OSSC is that you end up with the correct aspect ratio without having to fiddle with settings on the OSSC. As long as you set the Toro to VGA mode, you’ll still get 480p for games that support it.
The Toro definitely works in “VGA” mode over SCART into the SCART input of the OSSC because that is how I am using it. Doing this sends 480p over SCART, which is very handy. Here’s the info on sync from the manual:
8. Sync combiner circuit to output CSYNC (composite sync) through Scart or VGA connector.
9. Push button to select video sync output mode for the VGA: H&V SYNCs or CSYNC alone.However, they note later that the button only affects the VGA output, so you are always getting combines sync over SCART. The only difference is 31 kHz vs 15 kHz, ie 480p vs 480i.
RGB can come from the PC Engine. That is how my system is setup. However, you will need to pull audio from the interface unit. With a CoreGrafx, you get mono audio returning from the IFU to the system and out of the DIN jack on the CoreGrafx, but you have to grab audio from the IFU if you want stereo. I do not know if the PC Engine is wired to get any audio back from the IFU as I do not have one to test with, though.
It literally says on the top of the front page that they are not stocking SCART cables until at least tomorrow so some R&D can get done.
