With my PAL original XBOX, it happens that I get a random (as in, it happens once in a while, but consistently) temporary 'black screen', when I exit from a PAL60 game and return to the PAL50 system's dashboard. Usually, the resync takes a second or two, but in that case the wait is way longer (around 15 seconds). It's not a proper sync drop, because the signal comes back on its own, it just takes more time.

It also occurs - once again, pretty randomly and less frequently - when I boot a PAL50 game from the PAL50 dashboard. In this case, though, the screen remains black. If I press any button on the remote, that brings video back to normal.

It's not a huge deal of course, I'm just curious about what can cause this. It happens with stock settings and tweaked profiles, it doesn't seem to be connected to that. Nothing like that happens with my PAL Nintendo GameCube, which does pretty much the same (in the way it swings from in-game PAL60 to PAL50 system's UI). Worth noting that I start noticing this more since I swapped my original Microsoft RGB Scart cable with a C-Sync one from Retrogamingcables.uk (btw, I use the same kind of cable with the GC too).

Thanks in advance! ^_-
Softmod that Xbox. This way you can region switch it to NTSC and force 480p, 720p and even 1080i. Even with your "PAL" games. Every Xbox contains the NTSC code on PAL discs.

It's very easy and is a waste if you don't.

You might want to try "Full TX setup" in OSSC compatibility options in your display permanently loses picture during a mode switch.

Probably the best way to prevent dropouts is to use a presentation scaler/switcher, but that comes with its own problems, like full-time framerate conversion to 50Hz or 60Hz, depending on what you set the output to, and added lag from the framerate conversion and scaling.

That said, it's unusual that your TV would go black and stay that way. Have you tried using your Xbox and OSSC on a different HDMI display to see if it exhibits the same behavior under the same circumstances?
Thanks!
Yeah, sorry, I should have mentioned that I'm using an Asus PC monitor - not a TV - and that I'm aware of the screen 'pauses' during mode/resolution changes. This one, though, is kinda odd because it lasts noticeably longer than usual, but it gets back to normal, eventually. And to reply to Marqs:

Thank you too! I'll try that option anyway, even though the permanent drops only occur very rarely and only (as weird as it sounds) when a PAL50 game loads straight from the PAL50 dashboard. Rather odd, isn't it?

All that said:

Yeah, I'm seriously considering that now. I've always assumed it would mess with some games, or forced me to use backups (which I don't really want to, as I like to use original games), but it seems that it won't be the case, right? I still can't imagine how such a mod will work with PAL50-only games - there are a few of them - but hey, should be easy enough to track down a few NTSC-UC replacements, nowadays. :)

In my limited experience, Xbox games aren't tightly coupled to their region like PS2 games are, and a game that might otherwise be PAL50-only does not force the console into PAL 50Hz output, like the PS and PS2 would.

I've played all three Dancing Stage Unleashed games, none of which are PAL60-compatible, along with a handful of other PAL-region games, on my NTSC Xbox at 480p@60Hz (or is it 720p@60Hz? It's been a while), just as if they were the NTSC variants. Games just seem to play in whatever video region your console is set to, not unlike a typical PC.

There's possibly an HDMI mod coming for the PS and PS2. There aren't really any details at this time, so curb your expectations; but I'm hoping it'll have something that will address this.

I'm really hoping it'll be like the UltraHDMI, which has an optional scaler that provides full-time framerate conversion to your choice of 480p, 576p, 720p, or 1080p at 50Hz or 60Hz; it only adds about a frame of lag, it would let people in NTSC regions play PAL games, at the correct speeds, without needing a display that supports PAL (would let you display NTSC 60Hz stuff on a 50Hz panel, but multi-format equipment is more common in PAL regions), and it wouldn't drop sync during mode changes (very important for PS and PS2 games).

Amazing.
And 5 additional profile slots added? Already life-changing, for me personally. Thank you!

For the OSSC 1.6, is the HDMI chip inside 1.4 or 2.0?

I know that "ossc_0.82.bin" is to update, but what are all these 3 additional files for:

ossc_0.82-aud.bin
ossc_0.82-aud_jp.bin
ossc_0.82-jp.bin

?

I don't need japanese translation, so I am guessing I only need the following:

ossc_0.82.bin
ossc_0.82-aud.bin

Correct?

My OSSC is 1.6 and has audio in/out, so I guess I just need the "ossc_0.82-aud.bin" then, thank you very much.

You need the _AUD version if you have digital audio processing on the OSSC, meaning you either got a DVI version with additional audio board installed or if you got the HDMI version.

I have the HDMI version, I can get analog audio digitized for HDMI out by hooking audio through scart or 3.5mm.

Are the new 2018 LG OLEDs as compatible with the OSSC as the 2017 models were? From the C model and up these new TVs have a new processor, hence the question :)

yes, they are (at least as far as the 55" C8 goes).

On a German forum a user reports lots of dropouts with an SNES and OSSC in 4x/5x mode on a 55" C8 LG and rare, short dropouts even in 3x mode.

I'd dealt with the dropouts issue on LG sets before and I'll bet money he's got some combination of a bad HDMI cable and/or ground loop going on.

I made the first set of import profiles for the OSSC with custom labels (sans the last slot as I didn't use it). Please note that I found in my particular case I have to make Win32DiskImager write the file TWICE to the card before my OSSC will recognize the data (at least for firmware updates). So I always do this for profile imports as well. Also please note the 32X profile is tied to HD Retrovision cables, while the others are tied to RGBS SCART input.

As usual, sampling phase, H. backporch, and V. backporch are random variables on a console/cable case-by-case basis, so you may still need to adjust these for your given setup. Here's the import file link:

http://www.firebrandx.com/downloads/oss ... es_fbx.zip

Simply go into the settings option and look for the import function.

Cheers!

However, the same resolution of 720x480 is still going to be output, so the OSSC doesn't need to change its sampling or anything like that (assuming you're in DTV mode). It still falls to how the display handles a 960p image. I don't see anything on the OSSC wiki indicating that you can change the metadata it sends to indicate widescreen or fullscreen, though I would have thought that would be an option?
It would be really awesome if the OSSC could process the widescreen signaling (WSS) in the vertical blanking interval (VBI) on all inputs and translate that into CTA-861 compliant InfoFrame aspect ratio signalling. Section "4.1 Aspect Ratio" of CTA-861-G outlines how things should be handled between the AVI InfoFrame and the TV.
Harrumph wrote:Regarding 4:3/16:9 aspect ratio, I have already made a request to have this selectable via HDMI Infoframe. Though, it is possible this will ignored by most displays anyway, much like most displays seems to ignore the "IT content" Infoframe flag which is already implemented.

https://www.videogameperfection.com/for ... post-23226

Note that such an AR Infoframe flag would not in any way change how OSSC samples and outputs the image, it just contains a bit that says "active frame should be displayed in 4:3/16:9". I imagine this was originally intended for 480p HDMI signals anyway, so then it likely will not have any effect on an unusual format such as 1440x960.
Is there any downside to going all-out on CTA-861-G HDMI infoframes to explicitly flag everything like aspect ratio, RGB color space, full-range color, EOTF (traditional gamma with SDR luminance range), etc? Worst case seems to be some TVs that will ignore the metadata, so might as well enable flagging all this stuff by default? Could even pass display info from the OSSC over HDMI for the display to pick up for devices that support it (Yamaha AVRs will display "NintenoSwitch" on the receiver's front panel display when you plug in a Switch as just one example of this metadata display). Having all this under a master HDMI metadata on/off option would likely be the best UI option.
