Original Nintendo Logo from Firmware (switch-logo-patcher)

Many have been able to patch their Nintendo boot logo with the logo of their choice: https://gbatemp.net/threads/custom-boot-logo-for-switch.569031/

In the instructions for the excellent Switch Logo Patcher, used in the thread above, it mentions the ability to reduce the size of the patches but to date, there are no instructions to do so.

If you want to take advantage of the size reduction you will need to supply the Original Nintendo Logo from inside the firmware, but where is it and how do you extract it?

You might ask why nobody has simply copied the logo one time and shared it on this forum? The answer to that is here at GBATemp we don't believe in infringing upon the Intellectual Property rights of others. The Original Nintendo Logo belongs to Nintendo and is thus not to be shared here or on any other public forum.

The following is an abbreviated version of my journey to be able to extract the logo from a copy of the Firmware included on my Switch. I won't be including the Firmware here because it too, is the IP of Nintendo.


Thanks to the folks at #ReSwitched
friedkeenan (SLP Dev), Behemoth, shchmue, SciresM, Retroid, TSR Berry
for tolerating my n00bness and walking me through everything!

Thanks to @impeeza for providing some better methods here.

Down the rabbit hole we go...
  1. Download the following tools, unzip them and place them in your Windows path (or simply install it in the case of HxD and Gimp2):

    hactool (if you get a segfault or nothing happens when you run hactool, others have noted it too and the recommendation is to compile it yourself...which I've done here. Always scan for viruses!)
    hactoolnet
    HxD (any hex editor will do. I happen to use this one.)
    Gimp 2 (needed for importing raw RGBA data and converting it to PNG)​
  2. Procure a copy of your prod.keys from your Switch using Lockpick_RCM and copy them to your PC (preferably placed in %HOMEDRIVE%%HOMEPATH%\.switch\prod.keys as this is where most tools expect to see them)

  3. Procure a copy of FW that matches the version on your Switch. There are other tutorials that show how to extract your own Firmware such as this one using Goldleaf.

  4. With the FW zip file in hand create a working directory and unzip your copy into it. You will see a huge list of .nca files like this:

    C:\Users\wwiii\Downloads\switch\firmware\Firmware 14.1.1>dir

    Volume in drive C has no label.
    Volume Serial Number is 4AF0-ADF0

    C:\Users\wwiii\Downloads\switch\firmware\Firmware 14.1.1>

  5. Head over to https://switchbrew.org/wiki/Title_list and look for the VI module (this is the module that contains the logo) and take note of its TitleID (010000000000002D)

  6. Use hacktoolnet in your working directory to find the .nca that contains the TitleID we want

    Code:
    hactoolnet -t switchfs --listncas . | findstr.exe 010000000000002D

    C:\Users\wwiii\Downloads\switch\firmware\Firmware 14.1.1>hactoolnet -t switchfs --listncas . | findstr.exe 010000000000002D

  7. Extract the one that says Program next in the middle column using hactool

    Code:
    hactool -t nca --exefsdir 0da31addb3dc04f4cb27a6125803a0ce.nca_out 0da31addb3dc04f4cb27a6125803a0ce.nca

    NOTE: take a look at the Build Id: in the results of that command and you will see that it matches the has in the original code here. Neat, huh?

    1653961399363.png


  10. Aside from knowing you're on the right track, you will also see another number (called an offset) to the right of the hash: 1716480

    UPDATE:
    @impeeza has a fresh take on how to derive the necessary offsets for any Firmware without depending upon the code reference above.

    On step 10: You don't need the calculator; on HxD you can press CTRL+G and put the offset on decimal value and get on the Hex Offset:

    1654012509144.png



    I wish to know how to find the offset without looking on the script of the project https://github.com/friedkeenan/switch-logo-patcher/blob/master/gen_patches.py.

    I do this guide on several firmwares from 8 to 14 and searching forward for 00 00 00 FF 00 00 00 FF from start of main_uncompressed file found the beginning of the data:

    1654012921476.png



    And finding Backward the same string from the end of file get the last offset:

    1654012998241.png

    We will want to know what that is in Hex so open up your calculator (yes, THAT calculator) and put it in Programmer mode by clicking the hamburger (the three horizontal lines in the upper left-hand corner). Now click DEC (for Decimal) and enter the offset from above and note that it automatically converts to HEX for you! Neat, huh?

    1653962225751.png
  11. Open up the freshly uncompressed main_uncompressed file with HxD or your hex editor of choice and scroll down to the offset highlighted in yellow above: 1A3100

    @impeeza has provided another clever tip in his post.

    you can use the Select Block command (CTRL+E):

    1654013219229.png


    on that dialog, you can specify the start of the block and the length or the end of the same.

    You will know you're in the right place when you see sets of four numbers in the pattern of (R)ed, (G)reen, (B)lue and (A)lpha Channel. This is what's known as raw or RGBA.

    1653962706482.png


  12. Highlight the beginning at 1A3100 and then just scroll down until you reach the end of the pattern. In our case it happens to be 0x20C55F where the pattern stops with repeating zeros (0).

    @impeeza points out that you can derive the last offset by the size of the graphic (308 * 350 * 4 = 431,200 or 0x69460). You can simply add the size of the graphic to your first offset to get the last offset without guessing!

    1653964079148.png


  13. Click <Edit><Copy> (or Ctrl+C) to copy all of that, got to <File><New> (or Ctrl+N) to open a new file then hit <Edit><Paste> (or Ctrl+V) to paste the values in the new file.

    1653964828432.png


  14. Save the file as original.data by clicking <File><Save As> (there is no shortcut for this).

  15. Wake up the Gimp (2)and open your original.data file that you just saved.

  16. Since it is just raw RGBA data it doesn't know how to represent it yet so when you click open it will pop up another dialog where you will need to make sure to change the highlighted value below to match.

  17. Click <Open> one more time and your Original Nintendo Logo will be in focus and ready for the final manipulation!

  18. In Gimp, hit <File><Export As> (or Shift+Ctrl+E) . This time change the Name to be original.png and the file type to be PNG image (*.png) and then click <Export>.

  19. In the export dialog I only changed the compression to 0 and then clicked <Export>.

  20. The only thing left to do is to copy your original.png file to your switch-logo-patcher directory and finally run the full command!

    Code:
    python gen_patches.py -o original.png nintendont nintendont.png

  21. As you can see the new ips patch files are about 25-30% of the previously known good ips patches! Copy the entire patch directory to /atmosphere/exefs_patches/. (If you have an old set of the old patches be sure to remove the directory first.)

  22. Reboot your switch and enjoy your new lightweight patched logo!

Hey you, I just realize, when you build the atmosphère from source, it may be no the same of the one for the sigpatches are created, you need a new set of patches for that atmosphère files, here is where the great tool from @mrdude comes in hand: https://gbatemp.net/threads/autoips-sig-patcher.574126/ after test the package3 files build by me, some of my hombrew doesn't work until I generate new set of sigpatches. thank you very much @mrdude
don't really understand, but I'm also not part of the switch scene, so I don't know what package3 is.

I didn’t experience that when I did it. Just didn’t play the right games during my tests.

Went back and ran through everything installed on my Switch and found Luigi’s Mansion and an NSP forwarder to my own personally created power button .nro we’re both crashing!

Ran through the scripts and viola…it all works again. Something to be aware of when compiling your own Atmosphere, that’s for sure. That @mrdude is a pretty good…dude. Thanks for the PSA! Good lookin out @impeeza

Ouch...

Hahaha

I spend time this afternoon for nothing :rolleyes:
no for nothing, now you learn a new thing and teach your self a little bit about the files on the switch, you never will know when be usefull.

Thanks for your effort, now the scene had a confirmation about the new values for the script.

I don't know why is not my answer, I swear I did make a reply some time ago.

package3 is the Atmosphère loader binary. when you boot vanilla Atmosphère a bootloader is injected (fuse.bin) that bootloader loads the first step: package3 and then the rest of the FW is loaded.

:wacko: you may have a PATH environment problem, if the command pip says

'pip' is not recognized as an internal or external command,
operable program or batch file.

your installation is not on the path variable

go to next screen of python modify and be sure the path setup is selected:
