Fizeau

Adjust the color of the screen of your Nintendo Switch.

Features:

• Modify the color temperature of the display.
• Filter colors to one single component.
• Apply color corrections: gamma, luminance, and color range.
• Control the screen backlight brightness.
• Schedule settings to be applied to dusk/dawn time, with smooth transitions.

Installation:
Download the latest zip from the release page, unzip it to the root of your sd card (be careful to merge and not overwrite folders), and reboot.
Only the latest version of the Atmosphère CFW is supported.
If you want to use the overlay, you will need to set up Tesla (install Tesla-Menu and ovlloader). This isn't supported on firmware versions prior to 9.0.0.

Supported firmwares:
All firmares are expected working. The software was tested working on 1.0.0, 2.0.0, 6.0.0 and 10.1.0. If you encounter an issue running this on a particular version, please create an issue.
Settings:

• Settings are saved at /switch/Fizeau/config.ini, which you can also edit.
• To reduce the memory usage of the sysmodule, settings are not read continually. Instead, they are applied on application launch. Thus, you will need to launch the client after a reboot to restart Fizeau.

No SX OS support. Not interested.

Cool story bro.

Lol ok? I mean I have to use SX for my Lite, but the dev says he doesn't even have access to a Switch with that firmware to test. I'm just grateful this app is still being worked on.

Why even post that type of reply then? There's NO BENEFIT in posting "NOT INTERESTED" in a thread about homebrew. Just move on or be nicer about it.

Just implemented color filtering: this converts all the colors to a single component (ie red, green, or blue). This was suggested for use with high contrast games (eg VVVVVV).
Also I set up CI on the repo so you can grab nightly builds without me having to make a release.

Why these kids that keep complaining about lack of support for x or y just don't stfu, fork the repository and add support themselves? The heavy lifting, reverse engineering and research was already done by OP in the end of the day, so it's not like it would take Einstein to do the job.

It's almost like the entitled kids in GBAtemp can't code a hello world in C or even compile a binary... but I'm sure that's not the case. Is it? I'm sure all these anime avatars that love complaining have skills to do more than breath air and watch chinese cartoons all day.

Could you please upload the latest binary .nro here, 'cause on the github release page I cannot find any v2.0.0 new version of it?

 

[averne]

I guess it can get confusing when you aren't used to it:

Spoiler: Details

Click on the green check mark, then details on the popup:

Then artifacts, and download the zip:

Due to the way CI works the binaries are zipped two times over, though (I should probably fix that at some point).

It's sad I have to explain a meme so old: https://knowyourmeme.com/memes/chinese-cartoons

 

[LightBeam]

""Chinese Cartoons" is a term used to refer to anime, both ironically and un-ironically"
Well sarcasm doesn't transfer always too well in text so yeah, at least we have confirmation lol

Outstanding work there Averne! You're taking care of all our eyes at night The UI has been revisited and is wonderful. Keep up the good work. Cheers.

I'm also curious if the gamma correction means that it's now doing a true color correction as opposed to an overlay.

Also, the beta crashes SXOS on start-up, unfortunately. I'm using the latest version with SX Lite on my Switch Lite.

@averne

Can you give me more detail? A crash report would be really useful.

 

[mattyxarope]

I'm not sure if sx logs crash reports, do they? All I know is that I get 2168-0002 as an error upon boot. This happens with other incompatible sys modules as well.

Maybe @garyopa or @Alchemy_Gaming can give some insight on crash reports?

Yeah, without proper error reports I don't see myself solving this.
Something I'm wondering: if you put AMS sysmodules in /sxos/contents (or whatever), will it load them? That way you could be running pretty much an unmodified AMS.

Nope, you will get SX OS error screen with something about unsupported sysmodule version iirc.

Anyway possible for this to be used in an overlay like I just tap a button with Tesla and it selects the preset for the screen?

 

[KirovAir]

Thanks for this @averne! This helps my eyes a lot at night. Much appreciated.

 

[evertonstz]

Hey, averne I noticed the 2.0 version is capable of lowering the screen brightness pretty low. How exactly is that being done? You're actually lowering the backlight or you're somehow fooling my eyes using other methods? If you're actually controlling the backlight, do you think pushing it outside Nintendo's boundaries could bring any risk to the panel in the long run? Congratulations for the homebrew and all the research that went into reverse engineering everything, the new version is top notch!

Doesn't seem to be possible. Fizeau seems to be pro-automation in that regard.

You can select a profile to be applied to the screen in the applet client. The overlay can only edit the profile currently in use.

The luminance is different from the backlight brightness. The former only darkens colors without actually dimmering the backlight, so the LCD panel blocks more of the light coming from the backlight. Since the backlight isn't changed, it doesn't improve battery life, for instance. So no, I don't think it can possibly have an impact on the panel.
