(Putting this in it’s own thread for posterity…)

In case folks want to roll their own custom boot logo, here are detailed instructions for how to set it up.

Good article on getting python and pip (you need both) installed on Windows: https://www.liquidweb.com/kb/install-pip-windows/

Download the script by going here: https://github.com/friedkeenan/switch-logo-patcher

Click the blue Code button and select Download ZIP and then unzip the directory somewhere easy to get to.

Open a cmd.exe window and cd to the easy to get to directory and type the following:

python -m pip install -r requirements.txt

Once that’s successful your are ready to patch!

I’ve attached my 308x350 png file again for you to copy into the same directory as a proof of concept.

here’s the command:

python gen_patches.py patches_dir new_logo

new_logo=the name of the 308x350 .png file you copied into this directory that you want patched into files. If you download the attached proof of concept file it would be F44C1AC8-3310-4EA5-BFFB-1F682120F3B8.png

patches_dir=use whatever directory name makes sense to you. You will copy this entire directory over to /atmosphere/exefs_patches/ when you are done.



Here’s the readme again.

# Switch Logo Patcher

Creates the IPS patches needed to replace the Switch logo on boot.

The logo you want to change the Switch logo to must be the same size as the original logo, which is 308x350. Anything else and the program won't let you progress.

You don't need to dump the original logo to use this, but if you don't specify the original logo, each patch will be 400+ KiB.

### Usage

```
usage: gen_patches.py [-h] [-o OLD_LOGO] patches_dir new_logo

positional arguments:
patches_dir The directory where the generated patches will be
dumped
new_logo The new logo image

optional arguments:
-h, --help show this help message and exit
-o OLD_LOGO, --old_logo OLD_LOGO
The original logo image

I'm gonna try the sys modules thing again cause I was rushing before just alot of booting and shutdown lol

Did it ever play perfectly with just bootsoundNX alone in the contents folder? If we can’t even do just that…it’s probably your SDCard.

it still skips with just the bootsoundNX I'm using a SanDisk extreme 512gb

I run Sandisk as well. Some of them are pokey at times. Try adding another sound (leave the current one) and point bootsoundNX config at the new sound and see if it plays smoothly.

I will in a minute getting ready for bed. Someone needs to update bootsoundNX it's alittle over due lol

These changes for skipping sound went in about a year ago.

playing an MP3 at boot isn’t too tricky to be honest.

It only skips towards the end of it it's a 4second long mp3

I use the gamecube clip myself. Funny. It is towards the long side of the size you can play with this tool but it does play flawlessly as long as your Switch isn’t busy with other sysmodules and your SDCard isnt having issues. At this point, if you don’t have another SDCard to test with, I’m thinking you might want to back everything up (FAT32 partition AND hidden partition using Hekate) and then reformat your sdcard as FAT32 using rufus.ie.

Ohhhh. Very nice. I’m hex-boot myself. No SXOS? ;-)

There’s really only a few levers to flip during the boot process. By removing everything else under /atmosphere/contents/ we’ve removed all possible software contention that’s possible to add, leaving us with nothing but HOS. I know for a fact this exact boot sound works flawlessly on a V1 so it’s not HOS or the less efficient resources on the V1 platform. That leaves us with the I/O system. The weakest link in this chain is the SD Card. Much easier to address this by swapping out the SDCard. I thought my boot sound was screwed up due to a recent upgrade. Everything played but right towards the end there was a hard pause and then it would finish. I swapped the card and my gamecube Bootsound once again plays all the wa through with zero glitches. The card on the top was bad while the card on the bottom is the good one.

So I need a new sd card probably

I had a thought about this…you could backup just your FAT32 partition to your PC, format just that partition and then copy everything back. It would lay everything out continuously, including your mp3 file so the SDCard doesn’t have to seek. I know seek times are super short and it shouldn’t make a difference, but we’re running out of things to try.

Hello guys, I followed the tutorial but I do not know why I have the following error. May be you can help me:

The last line tells you what’s wrong:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\chino\\new_logo=holi.png'


In your command line, just put the file name. Move the file called holi.png next to your command for easier typing…

like this:

python gen_patches.py holi_patch holi.png

this will create a new directory called holi_patch and inside the new directory will be the patches that will include the graphics from the file holi.png located in the local directory.

Thank you very much, this short code "python gen_patches.py holi_patch holi.png" works perfectly!

@binkinator Thanks for the guide.
I made a change in my bootloader folder, before that, whenever I would go into CFW, I would get a custom image (fliped 90degrees) that would show the ticker line (instead of hekate), Im not sure how to get it back, would love help with that.

You bet.

You probably made a change to your /bootloader/hekate_ipl.ini. Please post the contents of yours here.

As for the op degrees thing, the splash logos need to be rotated 90 degrees counter clockwise. I have a zip somewhere around here with a whole bunch of logos, icons and splash screens. Let me dig them up…

E: found it.

Thanks, I was able to figure out the hekate boot logo and also make a custom boot logo using your guide, for the atmosphere splash, what is it that I need to exactly? Is there an easy guide for it? BTW I downloaded your logos and splash screens prior to this so thanks.
While I have you, I'm trying to optimize gaming experience when docked/handheld, is there some sort of way to do that using sys clk in a way that doesn't harm my system in the long run? I was thinking of the 60 fps mod for BOTW but it needs OC to almost max and even with that you need to run the game at a very low resolution, I gave up on that to try and see how I can play it in stable 30fps while in both handheld or docked which led me to see if there might be a way to set it so that all games are running optimaly, would love your take.

Hi, can anyone help me?

Trying to get my boot logo to show up. Already installed python, I used a 32bit file 308x350, and created the ips files. Put the folder into atmosphere\exefs_patches ...but nothing shows up.
Am I missing a config line in Hekate ?

Mine is

[Atmo SYS]
fss0=atmosphere/package3
emummc_force_disable=1

Hi I'm on 14.0 with a custom boot logo and went to update to 16.1 but once I select cfw emu in hekate it boots to a black screen. how do I turn the custom boot logo off? or make it compatible with 16.1
