Hacking Custom Boot Logo for Switch

[binkinator]

Thanks that worked. And just to be safe I left the folder name nintendont and just replaced the files with the Mario I made and it worked

Knew you could do it man! Now you can go crazy with any logos you want!

 

[laz305]

that would work for me totally aslong as i dont have to deal with commandlines

How can I make a bat file for this?

He left a link to the bat file in his previous post (not that you need it anymore cause you’re in the cmd line crew now.)

I've updated these boot logos for 14.1.0.

yep if you see the last entry is mine almost 1 year now, and my programming skills aren't so deep to reverse the process to create the patches on the script.

I'll be damned. It's you!

I've been wondering the same thing for almost as long. It bugs me that I don't know how to make them smaller.

yep I will like to make the smallest possible patch and do it "legally" I did get one from a obscure site but I don't know if is the original one and I am sure downloading big N assets isn't the more legal thing, extracting from your current firmware is a little more legal

A cool little homebrew to do it on the switch would be hella cool.

Here's my other "White Whale" for graphics...how to change the Sept logo.

is the sept logo the one on package3 file?

No sir. There are three logos after Hekate launched Atmosphere and they fire in this order:
1) Atmos Logo...this is the package3 1280x720 logo handled by this: https://github.com/Atmosphere-NX/Atmosphere/blob/master/utilities/insert_splash_screen.py
2) Sept logo...this is the white Atmosphere triangle (dunno how to create the RAW image required)
3) Boot logo...this is the 308x350 logo handled by this: https://github.com/friedkeenan/switch-logo-patcher

 

[impeeza]

so if you use hekate you have 4 boot logos!! cool.

Ayup. Each entry in my hekate_ipl.ini has it’s own custom splash.
I thought it was strange that people wanted to strip the logos off!
I added one for my Trinket M0 launcher as well.
Trinket passes to ArgonNX-SE which also has a logo.
The “Sept” logo (it’s actually the Atmosphere Logo) I would probably change it just enough that people would know it’s not stock.
I run my Switch like NASCAR…logos everywhere!

I just asked about Sept on Discord…let’s see what happens.

@impeeza

Just got this from friedkeenan himself:

yeah I need to make a script to do it for you but that requires effort
but basically at the offsets listed by <https://github.com/friedkeenan/switch-logo-patcher/blob/master/gen_patches.py#L9=L31> (the last entry is for the most recent FW version) there are `0x69460` bytes (`308 * 350 * 4`) of RGBA data that correspond to the switch logo
and you can dump that and convert it to a PNG or something and then use it

Spoiler: Code

Not going to lie and say it all makes sense but it’s a huge clue on how it works.

humm, I do forgot Argon, I actually use a R4s injector which comes with Argon payload v0.3 (I haven't be able to create a new payload with latest) so you are right:

RCM -> inject payload

• Argon Logo
• Hekate splash
• Atmosphere package 3 (normally i load package 3 on hekate) or if you load fuse.bin atmospehere triangle and then package 3 logo
• bootlogo (the nintendo switch one of the FW)

and in the last versions of Hekate & atmosphère the load time is reduced a lot. But if i don't use a "optimized" bootlogo the loading time is delayed up to 30 seconds.

The Hekate splash are great. I just buy a unpatched console for my nephew and be able to tell what payload is loading on hekate is a bless.

Awesome!

Is there a way of running a video file for the booting screen ??? Or I'm I asking a bit too much ??
Thanks in advance

unfortunately, there is no option for animated boot screens at this time.
