Is it possible to edit the contents of an ossc_profiles_0.86.bin file to make it compatible with the new firmware? Unfortunately the website hasn't been updated for this yet.


Don't think you can just somehow patch in the new firmware into an old config blob since adds new options, so the layout of the configuration data must've changed.

v0.88 is now released which fixes the profile import issue.

Thank you, everything is working great now :)

The new menu system really is a huge improvement. Tweaking settings is blazingly fast now :)

Could the existing OSSC hardware be used as a DAC?
Using the HDMI port as an input and outputting via the analog connections?

I'm sure this has been covered but since there's 9 million pages, I'll ask. There seems to be a large color shift for me when going from 3x to 4x modes on my OSSC. 3x looks great as is, but when switching consoles to 4x, the colors in 4x go to being much more vibrant and colorful or saturated. These are just with default settings. I'm curious as to why this happens. Is there any way to adjust the colors properly to bring the 4x colors back down a bit? I've messed with settings in the OSSC, but it's hard to tell if the color is changing much, despite heavily altering a lot of the OSSC settings.

Sounds an awful lot like your TV switching picture mode based on detected resolution. My OSSC produces consistent colors in all line modes

The OSSC is consistent indeed. I guess that your TV detects 3x as a SMTPE HDTV timing, while 960p is seen as a DMT/VESA/PC timing, so different processing, maybe even different RGB range interpretation is applied.

Yeah, this hadn't really occurred to me. It turns out, it's not changing picture modes, but settings are changing and some settings in my picture options actually get greyed out and can't be changed. Must be my TV automatically doing something to 960p content. It's not a deal breaker as I can obviously adjust color settings within my TV, just kind of a pain for when I want to swap around line modes.

Thanks for the replies.

I have a Samsung TV that behaves this way, when in "normal" display modes (480, 720, 1080) I can tell the TV it's a games console and enable Game Mode. However in any other resolution, mainly 960p and 1200p, the TV insists the input is "PC", has independent colour settings and higher latency.

And the latency goes up?! That seems weird if it's thinks a PC is connected.

Yeah, not by much.. I think it was like 12ms vs 18ms on the Time Sleuth, still slightly annoying!

Hey marqs, I've got an issue with 0.88's mode selection. It seems it is misinterpreting my PC-9821's output, which is 640x400 @56.4Hz (24kHz signal), as 384p (it outputs 992x384 in passthrough mode). Previous firmware work fine (excluding 0.87 which I didn't test since nothing changed), so I've had to revert back to 0.86.

Sega Model 2, PC88/98 and VGA 400p modes all have similar line counts which complicates mapping each to a suitable preset. Previously 384p was only enabled for non-VGA sources but 0.87 removed dependicies to physical inputs. I can update 384p preset parameters for next fw to avoid this collision.
