Chrono Cross on PS1 Resolution Switching with Black Screen

[erik343]

I know that when you have the Framemeister or OSSC Chrono Cross on the Play Station 1 has issues. When you go into a menu, the resolution changes to and from 240p to 480i, and then the screen goes black for a while (or permanently).

Is there any fix for this besides just playing the game on a PS3 with an HDMI cable?

I have a old PS1 that is collecting dust, and Chrono Cross was a birthday present like 19 years ago lol. So, I would be very happy if there is a way to fix this besides getting a CRT or something...

I believe the newer RetroTink offerings can survive a resolution switch handily.

Can you hook up the RetroTink to a Framemeister?

That is cool though, cause I want to just play on my PS1 and not on a PS3...

The OSSC has no issues. It leaves everything to the display, most of which have issues.

Pretty sure the RetroTink 2x is the same. To fix the problem you need a device that can change the refresh rate and resolution to the same so your display doesn't have to switch modes. That will probably lead to (minimal) input lag and judder in one of the modes though.

If you don't already have a OSSC, I would consider waiting for the OSSC Pro. It should be able to do this and so much more.

There are cheaper options, for example some of the cheap generic Chinese converters do this, but I imagine a PS3 would give you a much better experience than those.

Check out this video (especially round the 16:30 mark ) if you're handy with the soldering iron.

How do you even get OSSC to properly handle interlaced video?

My PS1 footage consistently looks terrible when the image is being processed. The deinterlacing process causes the image just just shake wildly, and it's super blurry.
I've been able to make Mr. Driller G look passable setting it to "passthru", but as I understand it, that does absolutely nothing and just lets the TV handle the signal? Either way, it still looks much much better on a real CRT. For the VS modes which I guess must be running a different resolution, it seems to just ignore every other scanline, creating a hilariously pixelated image on the HDMI output...

How do you define "proper" in this context? I think the bob-deinterlacing the OSSC does is mainly for compatibility with displays that, in addition to not accepting or understanding 240p/288p, won't do 480i/576i over HDMI, and it adds no perceivable lag--but you're right, it looks terrible.

I believe the only things you forego with passthrough are line multiplication, and maybe scanlines. Everything else, like sampling and low-pass filtering should still apply.

SuperSpongo,

Thanks for that video. I am going to buy one of the GBS Control units later.
Thanks!

EDIT:
When is that OSSC Pro suppose to come out? Because, I am going to start modding in like a few more months, I got other stuff to work on first...

I am using the Shinybow 6x2 SCART Switcher, and I am very glad that it has two outputs: one for my Framemeister, and one for the OSSC Pro! And, I don't have to buy a stupid CRT. I also am going to get a HDMI 12x2 Shinybow Switcher, just to select either the Framemeister, the OSSC Pro, or even my Nintendo Switch lol.

From what I've gathered (a combination of my own testing with RT2x, RAD2x, OSSC) the only way to accomplish this is by using a scaler that has a frame buffer. The frame buffer allows the device to smooth out the resolution switches (not a technical description), so your TV doesn't loose sync. But that's not the whole story, because as you say, the framemeister has a frame buffer and still looses sync during resolution switches. I've found that 240p->480i switching on devises that use zero lag techniques like Bob usually drop sync in the process, the length of which depend on your TV. The GBScontrol project seems to handle it much better. It doesn't actually have a frame buffer, it's more like a single field, since it has less than a frame of lag, but it manages to handle switching w/o the drop in sync. That makes it very appealing! You could wait for the complete units to be sold, or DIY if you're interested in an electronics project and not inept with a soldering iron. It's a cheap solution if you can DIY.

I have noticed that my TV (LG B9 OLED) sometimes gets locked into it's own idea of the best way to handle a source (like the HDMI switch I have my OSSC, UltraHDMI N64, & etc. hooked up to). On my ultraHDMI for example, sometimes I would get dropped sync in resident evil 2 (n64), like switching between menu/gameplay, or between camera angles resulting in me taking damage. There is a setting to enable a framebuffer to allow some extra image processing. That seemed to prevent the issue. However, after enabling it and then disabling it, the TV all of a sudden decided not to drop sync. I was like, "Huh?" I've also had issues with my HDMI splitter needing to be unpowered and repowered to clear up strange behavior like this. So, sometimes it's an artifact of the signal chain and settings the TV get's itself locked into behind the scenes. Sometimes I'll have no signal, unplug, reboot and everything will be fine.

I guess "proper" in this context would just be anything that doesn't look awful?
OSSC's primary feature is taking analog video and producing something that looks nearly as good as a CRT image on a modern display. Is there really no way to do that with interlaced video?

Have you seen 480i on a CRT lately? I find the OSSC's bob deinterlacing looks about the same, especially if you enable alternating scanlines.

[Sumez]

I'm literally splitting the same game between a CRT and my LCD HDTV as I play, and it looks like a million on the CRT.

especially if you enable alternating scanlines.

Where is this setting?

It's enabled by default, at least as of the current firmware revision. They were added in v0.71.

I have an OSSC and a Samsung TV and that handles res switching fast enough to not be an issue. I use pass through for everything except fighters. Had to go straight into the TV with the OSSC though, a HDMI switch added 2-3 seconds.
