THIS COLLECTION IS UP TO FIRMWARE 20.5.0, FOR THE NEWER COLLECTION UPGRADED UP TO FIRMWARE 21.0.0 GO TO THE POST: https://gbatemp.net/threads/custom-boot-logo-for-switch.569031/post-10765233

The name of each picture is the name of the compressed folder, inside each compressed folder is the original picture and the patches.


YOU CAN LOOK FOR THE OWNER OF EACH FILE ON THIS VERY THREAD. I DIDN'T MAKE ANY OF THE IMAGES, ONLY COMPILED, AND CREATED IN BATCH THE PATCHES.

No problem, your file lacked the patch for Firmware 21.0.0, here is the full set.

@impeeza do yoiu think it would be possible to explain how i can patch a custom boot logo to work with my fw and current version of atmosphere thanks i would really like to learn

Hola a todos,
Quiero añadir mi propio logo de carga entre los logos de Hekate, Atmosphere y Switch. Si es posible, entre los logos de Atmosphere y Switch. ¿Cómo puedo añadirlo? ¿Y cómo puedo hacer para poder jugar al casino Oro casino en Switch? Supongo que necesito modificar un archivo para ajustar el orden de los logos y el tiempo de visualización, pero soy nuevo en esto. ¡Gracias de antemano!

Actualmente no es posible añadir un logotipo extra entre el de Atmosphère y el de Switch de forma nativa. El proceso de arranque tiene un orden fijo y no se puede modificar mediante configuración. Lo más cercano sería reemplazar el logo de Atmosphère o usar un logo personalizado en Hekate ajustando su tiempo en pantalla, pero no insertar uno adicional en medio.

English

At the moment, it’s not possible to add an extra boot logo between Atmosphère and the Switch logo natively. The boot sequence has a fixed order and can’t be changed through configuration. The closest workaround is replacing the Atmosphère logo or using a custom Hekate logo with adjusted display time, but not inserting an additional one in between.

Hello there you can run three paths:

You have a picture for which you like to create patches.

On this case you can use the Python Script https://github.com/friedkeenan/switch-logo-patcher to convert any 308*350 size picture to a set of patches for all current firmwares.

in order to use that script you need to install the prerequisites Pillow and IPS:

pip install ips.py
pip install Pillow

Then run the script python.exe gen_patches.py atmosphere\exefs_patches\boot_logo "FULLPATHOFIMAGE" Where atmosphere\exefs_patches\boot_logo is the path for the patches to be created relative to current folder. and FULLPATHOFIMAGE is the full path to the image to be converted

Optionally you can add a copy of the original BootLogo in order to create the minimum size of patches, if you provide the original logo, the new patches will contain ONLY the pixels you need to change not all the pixels. on the post https://gbatemp.net/threads/origina...ware-switch-logo-patcher.613041/post-10763618 you can find the steps to extract the original logo from firmware files, that file should not be shared because is considerated copyrighted material.

In order to use that file the command should be:
python.exe gen_patches.py atmosphere\exefs_patches\boot_logo -o "FULLPATHTOORIGINALLOGO" "FULLPATHOFIMAGE"

You have a set of patches for older firmwares, so they do not works on newer firmware, but you don't have the original image.

Then you need to recreate the image from the patches and then run the script above.
Th is is a complex but easy process.


You need a set of files from one of the firmware for which you have. the names know so fare are:

So, if by example you have the D94508595598713DD2C3390BD0518C9A748D273F.ips file you need the set of files for the firmware 19_XX_X

and you follow the steps of the post https://gbatemp.net/threads/origina...ware-switch-logo-patcher.613041/post-10763618 using that set of files to obtain the «main_uncompressed» file and then using any IPS program apply the IPS file to the «main_uncompressed» file and extract the new bootlogo on that file which become the patched one.

thank you i was able to figure it out and got it working

Hi friends,
I found lately a package3 for the 21.1.0 firmware which appears to have been modified by kefir to support tinfoil 20 in FW 21.1.0.
I tried desperatly to modify or extract the splash with no success, with the methods i found on internet (insert_splash_screen.py + extract_splash_screen.py). I believe he inserted an additional code for his own boot but as my coding knowledge is 0 i was wondering if someone would like to try ?
I add here his package3 for 21.1.0 supporting Tinfoil.

 

[wxanges]

Here it is, new and working, without logo

 

[KaiLin]

Could you please replace the Atmosphere launcher logo with this PNG image? Image 1 is a size reference for the logo, and image 2 is a larger PNG image. My Atmosphere version is 20.5.

 

[froggy55]

"Could you please replace the Atmosphere startup logo with this PNG image? The first image is a size reference for the logo, and the second image is a larger PNG file. My Atmosphere version is 20.5."

im on fw 21.20 and i only know how to make the logo that replaces the switch logo just before entering hos the one you want is in the package3 file witch i dont know how to edit

Sorry SciresM asked to not share modified Atmosphère binaries, there are some threads about how to build Atmosphere from code

https://gbatemp.net/threads/building-atmosphere-on-windows-using-msys2.613446/

Also one thread about how to modidfy the files on the source code

https://gbatemp.net/threads/custom-boot-logo-for-switch.569031/post-9941051


But if you are asking about the topic of the current thread which is create patches for changing the bootlogos (the ones on the firmware)

You can ask to @DinohScene because the mods seems do not like to us to share bootlogos.

also instructions of how to create your own patches are ON THE OP OF THIS SAME THREAD.

 

[KaiLin]

抱歉，SciresM 要求不要分享修改过的 Atmosphere 二进制文件，网上有一些关于如何从构建代码 Atmosphere 的讨论帖。

https://gbatemp.net/threads/building-atmosphere-on-windows-using-msys2.613446/

还有一个帖子讨论了如何修改源代码中的文件。

https://gbatemp.net/threads/custom-boot-logo-for-switch.569031/post-9941051


但如果您问的是当前帖子的主题，即创建补丁来更改启动组成（构成上的那些组成），

你可以向 @DinohScene 询问，因为版主似乎不喜欢我们分享启动画面。

另外，您本帖楼主还提供了创建自己的帖子的说明。

Hello, is it possible to hide "AMS1.95|S" after the version number 20.5 in the Atmospheric Reality system, and only display "20.5"? Is there any way to hide it?

 

[impeeza]

View attachment 551703您好，我想请问是否可以在 Atmosphere Reality System 中隐藏版本号 20.5 后面的“AMS1.95|S”，只显示“20.5”？有什么方法可以隐藏它吗？

Mate, please remember this is a English only forum. please ask your questions on english so anybody can read them.

Second is possible, but you need to edit the Atmosphére code, and SciresM asked nicely to not post threads about it nor share modified binaries of Atmosphère, for reference: https://gbatemp.net/threads/remove-atmosphere-splash-screen.629387/post-10763704

Last, please do not seize threads, this particular thread is about the Firmware BootLogos and how to create the patches to cheange it.

I have no idea what you're talking about but the staff isn't against sharing boot logos.
I'd further like to ask you to stop spreading this misinformation and stop tagging me on said messages, thank you.

i dont know how to do this.. changing the switch logo before entering hos to this. i cant for the life of mine figure out how to use phyton or the script. if you may make it for me or try to teach me or if there's any easy tool that I can use

I had no idea how to do it, but by following the tutorials and instructions in all the threads, I managed to do it. I was even able to change the Atmosphere logo.
Keep reading and researching and you'll get it.

Hello there,

Guide about how to build atmosphère from source code, is for windows using MSYS2 but can be extrapolated to others OSes.

Summary of different logos shown at startup

Thread about the Atmosphère logos and how to customize them This specific post have a method for modding the boot splash

Remember SciresM asked to not distribute modded binaries
