Maybe this can help you:


How to create a file to change Atmosphère bin file and the build it:

Hekate Splash Screen:

First of all, thank you very much.

I followed the first link, all successfully. However, compiling then atmosphere... seems like a world to me. I have to dedicate more time.

On the other hand, I have seen that atmosphere includes a tool to patch Package3 and "inject" the splash into it.

I launch the script and although apparently the entire process is done, package3 is not modified since the default logo continues to appear. Could it be because you are using Mac Os? Thank you

Is that for color or B&W?

size

size

Okay. So does all of the logos that I have uploaded needs to be resized to 308x350?

yeah, the bootlogo is only 308 X 350 pixels, and the process only accept that size.

I've attached them all into a ZIP archive, just so I don't bloat this thread.

There is a Script for anybody, do not need to you install anything but can not use the "Original Logo" for create the smallest patches, so all patches created with it are the maximum size (570,042 bytes)

You can get it from:

https://github.com/StarDustCFW/Logo-para-switch.Palomitas/releases/

using the "Original Logo" you always get the smallest ips size.

Its true that I come up with the most BASED Switch logos imaginable.

I have repeated the proccess so many times and no logo works.
The ones provided are working.

I have installed pythoon, ips.py, pillow and image are PNG with correct size.
Do I need to use any special software to generate the PNG?

 

[josete2k]

Have you updated your py script from github?

I can answer you but I am afraid to be censored by a Jurassic mod, because will be a copy and paste of some old threads.

for using the friedkeenan-Pythontool you don't need anymore you have, if you are more confortable you can use this other tool https://github.com/StarDustCFW/Logo-para-switch.Palomitas/releases/tag/1.7 is similar only generate a little bit bigger files but have everything encapsulated on an only package so is download and run.

Thanks for your reply.
I'm an advanced user and I think I have found a bug somewhere.
I'm on 17.0.0 and using exfat.
When I copy the output folder to exefs_patches folder, sometimes it works and sometimes it doesn't.

What I tested:

1. I have deleted all ips files that are not needed for this FW version (only 5 are used).
Same weired result

2. I have injected multiple times the payload.
Same weired result

3. I tried renaming several times the output folder.
Same weired result

4. I was using sys-patch. I have disabled it.
Same weired result

So I think there is a bug on how ATM reads ips files on booting.
The only difference when you copy the same files multiple times are the metadata on the SD cache.
Someone need to make a debug to find why ATM are not loading the files.

*******************

UPDATE:

1. I tested the latest version of the software you provided, it works as a charm! The only issue is that it takes more time to show the logo, and the boot proccess is much more slow.

2. I found that I just need 1 file, instead of 5.
So, I dont know what these files generated by the script are used for, but I think the problem are on them. After deleting them, everythng works correctly:
