480p fix works... but issues displaying red

[WiiRVL]

After reading about newer Wiis being unable to display 480p correctly, I dusted off my old RVL-CPU-01 models of which I have two and fired up 240p test suite. And sure enough, the 480p patch works.

But now I noticed some weirdness when red objects are being rendered.

I made some comparison shots:

RVL-CPU-01

RVL-CPU-40

RVL-CPU-01

RVL-CPU-40

Note: this is with the 480p patch disabled on both Wiis
I tried my best with the photos. In person it's much more obvious.

Red text and sprites look much smoother on the newer CPU-40 Wii. Anybody else noticed that behaviour? Is there a fix?

This is a zero-order hold on the subsampled chroma. I had used an optimized setting for 4:2:2 component video decoders.

There is a setting that applies filtering to chroma, but it complicates the logic as it makes 480i/240p blurry.

Do you have a source for that?

How to enable it? I will only use this Wii for 480p. For 240p/480i I got my other Wii.

Use __VISetOverSampling(2) instead of __VISetOverSampling(3).

 

[WiiRVL]

I'm sorry but how do I do that? Haven't found any settings like that in USB Loader GX. Or can this be set system wide?

 

[Extrems]

You'll have to recompile it with a modified patch.

 

[WiiRVL]

Thanks for your help. I never compiled something so that's that. And by modified patch you mean just to change the value in the source code?

 

[Extrems]

Yeah, it should be a very straightforward change as long as you know where to look.

I notice you have at least one GameCube game pictured though. That would involve patching Nintendont.

 

[WiiRVL]

I have looked around files like video.h or whatever it's called. Didn't find the function. And if I find it I need to look into programming and compiling stuff. I have absolutely no idea where to start.

And if I want to patch Nintendont, would it be the same process?

At the same time, would all of this have a negative effect on the 480p patch?

Is there somewhere I can read about this? Would like to find out more. Thanks!

Oh I somehow missed your first post. Sorry about that.
I first read about it in this thread.

Thanks! I was only curious, as I have a mini and that only outputs composh1t

The Wii Mini can be modded for component I think.

I guess. But the cost of the modkit amounts to a used original Wii with Gamecube backcompat. It's not expensive but defeats the purpose.
