Best way? Perhaps for PS1 classics, probably straight up PS1 emulation via PS3. Not bad price to pay if you only pay for PS1 Classics that have this issue (e.g: Chrono Chross, Silent Hill).

[darkstrider2]

I believe Silent Hill is one of those games like Chrono Cross, 480i menu/maps, and 240p gameplay.

OSSC is handling a switch in video signal. So this is actually normal for upscalers, same thing happens with the Framemeister, but I believe Framemeister takes longer to do 240p->480i transitions and back.

@vasilas432 I had a extra 5-BNC to VGA cable to put Extron-out into the OSSC. If you were testing for sync drops, I still got sync drops.

[darkstrider2]

I use a BenQ Rl2755hm. According to displaylag, it’s 10ms. The smallest I’ve seen on that site is 9ms. Framemeister has 14-16ms processing vs OSSC’s 1-2ms.

I don’t feel the difference between OSSC and the framemeister whether I use that monitor or my HDTV (40ms). If I care about playing with least lag, I go play on my PVM, I can definitely feel it beats OSSC/Framemeister+LCD, esp with a game like megaman.

The only difference I can feel/tell is that the colors are better (more accurate to PVM) playing on OSSC.

However as far as Framemeister advantages over the OSSC, it’s near-perfect for 480i deinterlacing to 480p,720p 1080p versus settling for bobing with OSSC. Also with zoom, it can achieve 6x integer scale for GBA (almost fills screen) or 7x with GB/GBC (fills entire screen) if you have GBPlayer for GC or Super Gameboy. Also with Framemesiter, it can zoom the 480p PSP component output 4x + zoom to fill the entire screen.

Only issues is framemeister is that there isnt a FirebrandX profile for arcade boards except neogeo, so I have to use that or another 5x and adjust the zoom/brightness. Also, a sync stripper is a must for CPS2 to play nicely with the framemeister. Also, 480p scaling doesn’t look good, OSSC can passthrough or scale 2x for 960p and looks good, framemesiter cannot.

So I say,

240p : OSSC > Framemeister slightly
480i : Framemesister > OSSC
480p : OSSC > Framemeister significantly

To add: if my SCART extension cables coming don’t work/degrade the video quality to direct connect to OOSC, I’ll resign to use my XRGB mini instead for CPS2/CPS3. I’ve confirmed that Supergun -> PVM -> Extron -> XRGB mini -> LCD monitor doesn’t disconnect.

[darkstrider2]

Okay, I did CPS3 testing with just SuperGun -> PVMin -> PVMout -> OSSC -> LCD monitor (BenQ RL2455hm) and it did have disconnects every few minutes.

So you’re right, it’s not the Extron, it’s basically any ‘middle-man’ in between the SuperGun and OSSC that can make the OSSC drop for CPS-3 and below systems. So the OSSC is sensitive. And I’m sure the same issue can be found if someone tests CPS3,2 with a gscartw.

Looking over at [1], looks like other people have the same OSSC sensitivty problem with Extron and Line outs from PVM, and I’m sure this is an issue with gscartw, but for a very tiny minority of customers (because I’m assuming people get OSSC to support multiple consoles.

@Marqs , would this be something you can priority to look into the OSSC mode sensitivty with arcade boards (maybe for at least CPS3/CPS2) in the next few firmwares?

[darkstrider2]

If I understand you correctly, using a SuperGun -> any SCART switch w/ multiple outs like the gscartw -> OSSC -> LCD monitor .. will have eventual disconnects? It’s not just a PVMout or the Extron.

[darkstrider2]

Can’t do Test 2.0. My only BNC->M Scart Cable has a resistor inside it specifically for Extron crosspoint outputs that I didn’t mod myself. Even if I just used it, it’s not a good test because it’s technically not a ‘passthrough’ cable, so the OSSC will probably read something different. I don’t have any other BNC->SCART cables. Sorry.

I can make due without the PVMout, I ordered some extension SCART cables for my SuperGun SCART to connect direct long distance to the OSSC in my setup. I’ll just switch out the Extron Crosspoint output SCART and this one whenever I switch between arcade vs console.

[darkstrider2]

Connected SuperGun directly into OSSC and into LCD monitor. Can confirm no drops playing on both CPS2 for 30 minutes and CPS3 for an hour.

Connecting SuperGun to Extron Crosspoint -> OSSC -> LCD monitor, the first drop happened in the 1st 3 minutes.

I jotted down the input on the LCD screen of the OSSC w/out Extron and w/ Extron.

SuperGun -> OSSC (CPS3): 265p 15.73khz 59.37hz
SuperGun -> Extron-> OSSC (CPS3): 264p 15.72khz 59.56hz (I did see it as 262p 15.73khz 59.59hz for the 1st 5 seconds when I turned on the supergun)

Ok, so I’m convinced the Extron must be doing something to the signal. I remember connecting supergun -> PVM-1-out -> Extron -> PVM-2-in only worked if I added a sync stripper SCART->BNC before the Extron, PVM-2-in showed faded green video straight out the extron, with video acting like there wasn’t sync (ext sync was turned on). If I did SuperGun -> PVM-1-out -> PVM-2-in directly, PVM-2-in reads the CPS2. Only with the sync stripper to the Extron would the Extron output correctly to the PVM-2.

So @Marqs, so what you think happens to the signal if it goes through as Extron? Is CPS2/3 feeding variable sync which the Extron has to readjust?

It just seems like there’s not much I can do at this point except hope in a firmware upgrade fix, if Marqs ever gets a chance to test with Extron Crosspoint w/ ADSP models and test with arcade boards.

[darkstrider2]

So I tested it just now. I tested with both with and without ’10+’. It didn’t matter, CPS3 was still dropping.

The weird part is that I’m able to play CPS2 a whole MVC1 for a whole 30 minutes with no drops. So feeling that it’s not gonna drop, I switched boards. But once I switched systems to a new one(CPS3) (w/ OSSC still on) the OSSC started dropping. At that point (OSSC w/ ’10+’ didn’t help). But then when I switched back to CPS2 w/ MVC1, I started getting drops within 3-5 minutes of each other (restarting with OSSC w/ ’10+’ didn’t help either).

So I’m stumped. It’s good with the first input I give it. But when I switch arcade system it’s dropping and switching back, that system begins to drop as well.

[darkstrider2]

Ok, I’ll test tonight and let you know. So I just turn on OSSC and press the “10+” button, then turn on CPS2? That’s it?

[darkstrider2]

Did it happen with the Extron or with?

[darkstrider2]

Did some testing today. Without modifying my setup, OSSC freshly rested a full day, I ran CPS2 didn’t cause any sync drop with OSSC (30 minutes), full game of MVC1 and Puzzle Fighter. I switched my SuperGun to the CPS3, I got sync drops at random every few to 5 minutes. I switched back to CPS2 MVC1, and I got sync drops every few to 5 minutes. The OSSC was on the entire time when I was switching. Couldn’t replicate the ‘no drop’ behavior when the OSSC first turned on.

I held the OSSC at the bottom and it felt really warm and I went to turn it on. I wonder if it’s load and temperature dependent when it’s starts randomly dropping systems with odd frequencies.

[darkstrider2]

Yea, I have a 1.5 with installed audio HDMI which came with 0.76a-aud, no difference. And I’ve tried DVI TX mode today, still random drops.

[darkstrider2]

Yes, all my consoles/SuperGun RGBs connects to the Extron with csync. Yea, tried everything.
