HDMI Retro Console > OSSC / Mcable

[zack__1987]

Hi there!

I have a PAL Gamecube with the EON GCHD adapter MKI, OSSC and a Mcable Gaming edition on the way home.
Also a N64 UltraHDMI mod kit preordered for my PAL N64 and planning on having a Dreamcast HDMI kit.

The point is that I was wondering if I can route the GC or any HDMI modded console to the OSSC but didn’t find so much information about it.
I received today this that maybe could help?

The thing is if there is a point on doing that…
I’m also waiting for a Mcable Gaming edition to arrive home and was thinking what could be better?

HDMI console > Mcable > TV
HDMI console > OSSC > TV
HDMI console > OSSC > Mcable > TV

Anyone can help since there is not too much information about this? Thanks in advance!

You can, but why would you?

Particularly the UltraHDMI is already more capable than the OSSC in terms of scaling (framerate conversion, overscan, gamma boost, CRT bloom, scanlines); and, by converting to analogue to route it through the OSSC, it’ll no longer be a digital-to-digital solution.

If you’re just trying to route multiple devices through an mCable, just connect your devices to one or more Vorke HD41 Pro HDMI switchers (known compatible with the OSSC and up to 4K@60Hz) and use the mCable on the output.

I was thinking on this because of the line multiplier factor, to improve jaggy edges… For that too I was thinking on the Mcable as you can see here:

Also in this topic you can see something related where the Code Veronica screenshots are:

What I’m questioning is routing the output from your HDMI consoles through the OSSC, not the use of the mCable.

The UltraHDMI and DCHDMI already do scaling internally; and I’m not sure which clone consoles you’re looking at, but (correct me if I’m wrong) I’m pretty sure those will have selectable output at 480p, 720p, and/or 1080p as well (should do at least 720p like the NES/SNES Classics).

The OSSC isn’t going to provide any benefit to the already-scaled, already-digital output from these devices.

Looks like the smoothing filter RetroTINK applies.

For Gamecube, might just be better to upgrade to a mark 2 GCHD. GCHD MK 2 and GCDual have full RGB analogue out. I route mine through the OSSC and use the 480p x2 mode, I like the look better than the digital output from GCDual (without 480p x2) and there’s no loss in quality that I can see with a shielded cable.

For N64 I’d say the only reason to bypass UltraHDMI was to minimise input lag, in which case you can use direct mode with a HDMI to VGA adapter. N64 is an odd beast and better suited to the UltraHDMI’s custom scaling and debluring system.

DC HDMI, I saw Dan do some comparison shots, things are very close between OSSC and DC HDMI. If you don’t need the convenience of HDMI on your Dreamcast OSSC is still a great way to hook it up (especially via Toro SCART).

There is any difference in the video quality in between the MKI and the MKII?

[nmalinoski]

Mk1 and Mk2 should both have the same GCVideo hardware; however, I believe the Mk2 ships with a newer firmware. You should be able to update the firmware in your Mk1, but it’s not straightforward. I expect you’ll need to take it apart, solder a header to the PCB, and use a USB chip programmer to get the firmware on there.

Good to know!

I’m now here testing the PS1 with the new Pound HDMI adaptor to HDMI routed to the OSSC through the Tendak adaptor I posted before and then to the TV.

Is it me or there is no line multiplying going on? In the OSSC screen says 750p resolution…
Here I post some photos for comparison, don’t know if the OSSC makes the image looks sharper or just saturated…

The pound cable already does scaling to 720p (with no option to disable, as far as I know), and the OSSC’s screen describes the incoming signal, not the outgoing signal; which means that 750 line count is [probably] correct. The OSSC doesn’t do any scaling to HD content, so there’s nothing for the OSSC to do with the output from the PS1/PS2 Pound cable except maybe add scanlines.

[zack__1987]

Yes, you are totally right… I tried to route it from the pound cable to Framemeister for nothing too…

I think my PAL PS1 on Lx5 mode on the OSSC should look crispier that the pound cable but I have a lot of trouble with the settings to have a nice image centered just in Lx2 mode =(

[BlueStinger]

you can fix that in the sampling menu. The PAL PS1 will look the best with RetrogamingCableUk cables in 5X (generic 4:3)
Hsamplerate 2046
Hsynclen 150
Hbackporch 190
Hactive 1600
Vsynclen 3
Vbackporch 14
Vactive 240
These are what works for me in 1920×1200, looks absolutely perfect

And from my experience, Xbox HDMI Pound cables are not desirable. I’m glad I bought mine before MetalJesusRocks talked about it, I managed to resell it for 3x its original price. As for the others, I watched reviews, they all have major drawbacks (color accuracy, black crushing, video noise) and I don’t know about input lag but I would be surprised if they are appalling.

Yeah, the Pound cables are solely for convenience; you should stay far away if you care even one iota about picture quality.

I know that Puond cables are not the best option out there but my Samsung Qled 4K TV seems that not work with 1920×1200 resolution… don’t know what to do… I already have the RGB sync-on luma SCART cable from retrogamingcables.co.uk to test it but can’t figure out how to manage…

Anyway I will try on these days and as I received the Mcable I will try the Pound cable adaptor + Mcable to see how it looked like too.

[BuckoA51]

Line 5x mode is hardly mandatory. My TV supports it but I don’t even like it that much, I prefer the more analogue look scaling 4x provides.
