Thank you man it helped solving the issue and everything almost works with some tweaks.

The only problem i seem to have is that for some reason there’s an option called NTSC Values where you can choose Svideo, Composite and RF signal, but the values you can choose are only 0 and 1, so possibly without the RF option to be chosen, and the problem is that changing to 0 for Svideo doesn’t work, it is stuck at composite. Other than that everything so far seems working and autoPhase selection is correct.

[GPDP1]

Right, that “parameter” does nothing, because what it actually is is instructions to set the NTSC Fringing and Artifacts values to 0, 1 or 2 to replicate S-video, Composite and RF respectively.

[BiRaitBec]

Got it!

Yes it works man, splendid thing you did!

[MajorPainTheCactus]

Ah great thanks! Ill no doubt plug it in when I look at doing this - possibly next week as Im off on holibobs.

[MajorPainTheCactus]

Thats fantastic! I might have to try this out myself. I remember back in the day everybody was trying to get sharper clearer images now everybody wants to get blurrier noisier images. (And rightly so I hasten to add if thats your cup of nostalgia tea)

About ntsc on normal shaders like the default from mega bezel reflective shader the auto ntsc never leaves as default the one with more color bleed, like in sonic phase 2 on megatron is dark blue and the red shooes are violet…like not even the worst composite will give you those results. In mega bezel auto ntsc works properly. Also in ninja gaiden fences and shinobi iii waterfall.

@MajorPainTheCactus

I might have to try this out myself.

I almost forgot, you can also try out the Blargg NTSC video filters available in many cores’ core options as well as my CyberLab Custom Blargg NTSC Video Filter Presets, my older Blargg NTSC SNES Custom pseudo presets, which are included in RetroArch and finally my latest, 3rd Generation Custom Blargg NTSC Video Filter Presets in my new CyberLab CRT-Royale Death To Pixels Shader Preset Pack.

They should all work fine with Sony Megatron Colour Video Monitor!

[BiRaitBec]

Yeh man i actually even tried those, i had the best image quality to my liking with the custom pseud MD one indeed, however none were resulting in clean ntsc like latest guest with svideo type.

Your preset package is on similar level as to guest and mega bezel as far as overall uniqueness of the shader presentation, but with megatron the mask is on an other level for me and is the one i look for in crts, especially the aperture grill.

I miss an overall better file naming and file location as with the old presets of yours, which i still prefer above all, together with the old blargg filters, but that can be absolutely subjective.

Look forward to what you come up next, you are one of the most active preset creator and you have grown up a lot in these months with the tecniques.

I was actually one of the advocates for the improvement of the Colour bleeding which was the start of the most recent overhaul of Guest-Advanced-NTSC.

Since then I’ve released my 3rd Gen NTSC filtering stuff but for now they’re only available as part of my CRT-Royale Preset Pack. Have you tried those yet?

Maybe you can elaborate on these a bit more in my thread.

Thanks, I appreciate that. I recently got Sony Megatron Color Video Monitor to work properly and was tweaking away so hopefully I’ll be able to make a little Sony Megatron Color Video Monitor pack once I’m able to iron out all the minor kinks (mainly with certain colours).

Sorry if this already explained, but what TVL/ mask type/display resolution in params settings are appropriate for 1440 screen, would 480/600p content work or only lower? Basically I’m using the windowcast core to capture content.

[Jamirus]

It depends on how many pixels the mask use. In your example 2 and 3 pixel masks are appropriate for high res, which should be 1080p /600 TVL or 4k / 800 and 1000 TVL.

[ZxPlayarr]

480p content in any of the settings you give me (note:integer settings don’t effect 480p content it seems) with slot mask selected, there’s horizontal lines on the screen. I’m not sure if that is how it supposed to look or a bug.

[Jamirus]

No idea, I don’t use the slot option in Megatron for a number of reasons (looks weird to me at low resolutions, requires certain scale factor, sdr requires too much brightness…) .I only use the other two masks on my Surface (1504p). I haven’t tried anything with the Windowcast core, but in my experience Megatron also absolutely needs integer anyway.

[Retro30]

That looks cool thank you

[MajorPainTheCactus]

That looks like the scanlines are merging into each other too much. Maybe try reducing the vertical max ofvthe red green and blue channels to see if it goes away.

[MajorPainTheCactus]

Just to say I never use integer scaling and theres nothing in the shader that requires it. Maybe its the vertical parameters on the scanlines being a bit to exaggerated for low resolution displays. Are you seeing moire effects?

[Jamirus]

It looks like the scanlines don’t quite match, although in my memory it used to be considerably worse. Here are examples taken on my 1200p monitor, base images are 224/256 lines. If you decrease the possible scale factor further (e.g. 350p PC game in the last example), then it becomes totally obvious that it’s not correct, but I don’t know if there’s any other shader who manages to deal with it in such circumstances.

[MajorPainTheCactus]

Im not sure I see too much of an issue in the first two images but I can certainly see it in the blue in the last image. At these low resolutions I suppose it is going to show up variability in the number of pixels devoted to a scanline. Potentially reducing the vertical scanline attack and making the min max range larger may help.

On a side note what is that middle game?

On a side note what is that middle game?

Looks like “subtrade” from 1992: https://youtu.be/tGY5r4Xi_yo?t=237

I’m not familiar with this one, either. Seems similar to M.U.L.E., though…

[Jamirus]

Yes, it’s Subtrade: Return to Irata.

Irata (read it backwards ) is the planet in M.u.l.e. .

[hunterk]

lol that explains it!

There was a poll on Twitter awhile back for people to name the book/comic/video game that they would give the big-budget movie treatment and M.U.L.E. gets my vote

(that or Horse Master)
