I’m surprised the volume gets cut unless they are both on at the same time.

TRS and TRRS are just descriptions of the connector structure Tip-Ring-Sleeve (or 2 Ring for TRRS). The standard 3.5mm audio connector you see on headphone cables or the y connector you are using is a TRS connector. If you want to ensure isolation you need to use a 2 (or more) in to 1 out switch.

I assume you are maybe using component Y-Pb-Pr for both consoles, how are you switching between the video? It’s rare to see a component switch without any audio ports as well.

A quick search indicates that VHS does not encode rgb data and few (if any) devices supported that as an output format. So the scart output on your VCR is probably composite (although you mention s-video cables, so maybe it has a dedicated s-video output? the manual pictures didn’t indicate this).

The retrotink should work for you, but you would have to use one of those scart to rca breakout adapters I’m guessing?

Bucko explains in this thread why you might prefer to use the scart output on the toro.

Dreamcast Toro + OSSC = Scart or VGA?

Either will work however if you have a particular preference due to other switches/cables/connectors in your setup

Is it possible this is being caused by an issues related to an interlaced signal? Can you try changing the output on the ossc for 480i (or whatever the pal equivalent is if applicable) to 2x mode if it’s not already? or picking a game that explicitly lets you set progressive mode and seeing if that changes anything?

it doesn’t randomly happen with ‘certain types of panels’.

Nowhere did I say random. Nor did I say only the OSSC could ever cause this.

it’s been proven how IPS displays

Are these not certain types of panels? I’m incredibly confused as to why you took issue with saying certain types of panels. I couldn’t remember the specific type of panel, but I remembered seeing a previous post where someone (likely you, since it also mentioned 3DS XL screens) explained this.

It doesn’t change the fact that using bob-deinterlace (such as this function used by the OSSC) on certain types of panels (IPS ones perhaps) can cause this unfortunate issue. I’m not sure anyone is claiming the OSSC does something wrong, just that people aren’t understanding why this happens or aren’t aware that it will.

As far as awareness, I’m not really sure anything will really solve that. People still regularly install the non-audio firmware and then ask why there is no sound. Not everyone reads the wiki, and many people probably don’t follow the various forums religiously.

The Bob-deinterlace seems to cause this on certain types of panels. It has a similar (thought not as severe) effect on my monitors, especially with text. I left my PS2 on at the launch menu at one point and that got burned in for a couple of hours.

This is likely caused by some kind of stretch scaling artifact as bucko says. Generally something that stretches the vertical disproportionately to the horizontal.

I’m not familiar with other dvdo products, but on my dvdo duo I can change picture aspect ratio, active aspect ratio, and zoom +/-, without distorting the scanlines. However, actually changing the vertical stretch independently will result in similar patterns to what you show.

Then again, I recently tried a lumagen HDQ and no matter what settings i changed (after messing with it for hours) I couldn’t get it to not have those distorted scanlines. So YMMV.

The audio port you are referring to is not intended to be an AV1 input. It’s supposed to be an AV1 audio output, or an AV2 audio input, which is toggled by the small switch next to it.

It will function as an input for AV1 if it is set to AV1 output and the scart audio pins are otherwise not wired up I think I remember seeing, but generally I don’t think (and someone correct me if I am wrong) it was intended for feeding input audio from a gen/md model 1 headphone jack.

You may have better luck with a sync on luma cable for the N64, that is what I always used on mine before I put in the hdmi board. Some mods have a specific spot to hookup csync, that one doesn’t seem to. From what I remember some board revisions have csync hooked up anyway by default, some don’t.

[ErebusMaligan]

You would also need a D-terminal to 3 component male RCA adapter. Many of these are marketed as adapters for cameras of various types. If you get this, then yes it will work fine plugged into AV2. This is what I was using on mine before I went to an HDMI adapter.

[ErebusMaligan]

The OSSC have the 3 inputs for component video, but how it will handle the audio from the PS2?

You can hook this up to the Audio port around the corner from the scart socket, input as long as you toggle the switch. You will need a 3.5mm male to 2 rca female adapter

[ErebusMaligan]

Yeah, it really depends on how you are trying to balance cost/availability/simplicity/quality

I started with an XRGB mini, and while i personally rarely use it anymore, i’d still recommend it to someone starting out for it’s numerous options and high compatibility with pretty much everything. It’s inherent noise in solid colors issue though, drives me nuts now. It’s something I just can’t un-see (although it’s not as evident on stuff above 240p if you aren’t looking for it). Although to be fair i could never get scanlines to look right to me on it, and those would probably hide that noise. It is however, pricier than an OSSC, so YMMV.

For overall preference though, I’d recommend an OSSC feeding into a DVDO machine of some kind. Though again this costs more than just an OSSC obviously.

My personal chain for PS2 480i is a Videon Omega One -> OSSC -> DVDO. This is the only way I could get scanlines to look the way i want them. The Omega One seems pretty rare though.

By default most of the games on a PS2 are going to be 480i, and while I’m a huge fan of the OSSC, its deinterlacing is… concerning. For me personally it causes some serious (though so far temporary) burn in on my monitors due to the high flicker rate. So if 480i is your primary use, I wouldn’t recommend it personally.

On the other hand, feeding it to pretty much any other de-interlacer, and THEN to the OSSC as 480p looks great. This is especially true if you want to add scanlines, or if you have a final processor or display that handles 480p x2 mode (with or without scanlines).

I have a DVDO Duo and I’d recommend that over the OSSC if it was exclusively for PS2, they can occasionally be found for a decent price.

I tested this on my setup. I’m using a 32x on a CDX, and an everdrive. I got the same dropouts during the crusader of centy opening screens up to the point where you make your character, like 2 or 3 sync drops as it transitions between the different screens. I could not reproduce any drops once in game while going to the save screen though.

I’ve previously played through Phantasy Star IV without any problems the entire game with the exact same setup/settings, so seems to be something caused by the specific game. You mention some other games, do you have a list that you observed this problem with?

Edit: From what I can tell this is not due to a resolution change, says 262p on my ossc screen the entire time.

[ErebusMaligan]

Ah yeah, i wasn’t running a game on the N64, just my Everdrive startup menu which yes runs in interlace. When I actually run a game that isn’t interlaced, the delay is 25ms.

The PCE is a DUO-R from doujindance on ebay, although i added a switch to toggle between composite video as sync and a version i run through a sync stripper board. Not sure if that effects anything in terms of refresh rate, but it makes the picture clearer on my setup.
