Thanks! That fixed it. May I ask what the intended purpose is for switching it to AV1 Out? Wouldn’t the audio travel over HDMI for the RGB input in either event?

[wryguy87]

Will take a look at HDMI ITC and see what happens. I’ll also try to take some photos of the blurriness I’ve referred to for your reference when I can.

So thanks to the input here, I suppose I at least understand the issue with why the Dreamcast image only fits in the screen in 960p. It is in fact an overscan issue, as when I switch to the Wii 480p fits the screen perfectly and 960p there is empty space.

So clearly certain Dreamcast games are making use of the overscan area and the Wii does not. Of course I do see the same issue with the Wii in 480p where the image is distinctly blurry and washed out via the use of passthrough.

Unfortunately I have no way to address it via TV settings, particularly for the Wii because 960p breaks certain settings on my TV such as the ability to customize the screen size. That would at least fix the issue with Wii games not taking up the full screen, though even using passthrough on the Dreamcast I can’t do a thing to get the full image on the screen even with all the normal TV settings.

If the OSSC can’t offer some kind of overscan solution in the future there’s probably no helping it for the Dreamcast.

Switching back and forth between Wii and Dreamcast brings up something else I’d like to suggest.

#4: The option to choose between 4:3 and 16:9 for 480p x1 and x2 (960p) outputs.

Like with about everything I mentioned here, the issue is with switching between the Dreamcast and everything else. The Wii is of course a widescreen console, and because you can choose 16:9 for retro devices like the Genesis and Nintendo 64 that all plays nicely together. But because you can’t choose to optimize for 4:3 for 480p the same way you can for 240p, the Dreamcast image will be stretched.

There could very well be a solution I don’t know of, since that’s already happened once or twice but just trying to contribute to the project.

Also thanks for the tip about #2. If you’re curious about how this would work with a harmony, the remote can learn and imitate the signals from another existing remote. It simply asks you to point the old remote at the Harmony’s receiver as you’re pressing a button so it can learn the input. I’ve transferred all the actions that I knew the original OSSC remote was capable of to the Harmony but I missed that one.

It can also perform sets of inputs in a pre-specified order. As part of changing consoles, the remote will of course change inputs for the TV and AV Receiver, but in addition to changing the input on the OSSC there will be a two step command where it sends the input of the -/– button, waits one second, then pressed the input of the appropriate profile.

It’s a very handy remote, even if they’re a bit on the expensive side. I was lucky to get it for sale during a Black Friday clearance.

Unfortunately I don’t think my TV has that option. It’s a 55″ 4K Samsung set from around 2015. Will see if I can find anything relating to overscan.

For passthrough, the image looks like it has a distinctly lower level of color quality and sharpness compared to before. It feels like the HDMI signal is being passed straight to the TV and its scaler is doing all the work, resulting in a lower quality picture than what older versions of the firmware provided. You are right through that I can turn on scanlines which implies the OSSC is not just passing the signal along so maybe this is just in my head.

When I switch between passthrough and 960p though there is a very distinct difference in sharpness to the picture. 480p is blurry and 960p is sharp and pixelated.

[wryguy87]

Nonono, unless I’m misunderstood we no longer have the option to have the OSSC process 480p video before sending to the TV. I can only seem to enable passthrough or line doubling to 960p. Both of which have issues in that passthrough looks awful on my TV in addition to not being able to display the full image on certain games like Capcom vs SNK 2, and 960p semi-breaks my TV even if the full image displays.

Thanks for the note about #2, I’ll check that today.

How will this work if you bought an older version of the OSSC but want to jump back in the wait list for something newer like an HDMI version or (theoretically) some future version that can upscale to a 4K display?

[wryguy87]

Alright, I’ve tested with a Sega Genesis I picked up and the issue seems exclusive to the modified N64. Is it possible this is a common problem for modded consoles?

[wryguy87]

Didn’t notice anything unusual when using 240p test suite on the Wii. This issue seems pretty much exclusive to the RGB port best I can tell.

[wryguy87]

It’s an NTSC N64. Funtastic model with the newer RGB64 modification that works on all consoles. Tried two different varieties of RGB cable, which does include snyc-on-luma.

I don’t have another RGB capable console at the moment, but that’s worth a shot. I could pick up a Genesis and get a cable.
