Hey. I'm gonna show you how to install a custom font on a Nintendo Switch.

This is the Super Mario Sunshine font showing on Home Menu and some other games that use system font.

The easy way (recommended)

- Get NXThemesInstaller
- Drop .nro into sdmc:/switch
- Add TTF fonts to sdmc:/themes
- Launch NXThemesInstaller
- Install the font
- Reboot CFW
- Done

Spoiler: The old way

This was before the NXThemesInstaller font support exists.

What you need
BFTTFutil


Creating BFTTF - Binary Café TrueType

First of all, we are going to convert TTF/OTF to BFTTF.

Put both BFTTFutil.exe and the .ttf or .otf in the same folder.

Open up PowerShell or Command Prompt and type this command

BFTTFutil.exe -enc_nx Delfino.ttf Delfino.bfttf

or

BFTTFutil.exe -enc_nx Delfino.otf Delfino.bfttf

You'll get the BFTTF

Thanks to @p-sam for finding a way to load fonts via LayeredFS so we don't need to permanently replace system files thus risking a brick.

Copy the bfttf to D:\atmosphere\titles\0100000000000811\romfs
Rename the bfttf to nintendo_udsg-r_std_003.bfttf

Go to D:\atmosphere\titles\0100000000000039\flags
Create a new file as fsmitm.flag

Boot in Atmosphere CFW.

If you get past the Nintendo Switch splashscreen, congratulations!

Known issues

Filesize limitation
For some reason, fonts can't be bigger than the original font, the font (bfttf) has to be less than 1.95MB or else your Switch won't boot. You could try trimming some unused characters with FontForge.


Happy font hacking!

Very, very nice and great tutorial!
The console is 200% cuter with Super Mario Sunshine font haha

Hope no one bricks their system because of a font hack, though ^^'

Nice! Commenting so I remember to mess with it

I’m guessing this requires sigpatches? If so you should probably mention it in the post

Yes, that's why it's needed to boot CFW. Otherwise it hangs on Nintendo Switch splashscreen lol.

Atmosphere doesn’t come with sigpatches though

Wait what, I didn't know that. I always get Kosmos stuff

Yea, regular Atmosphere doesn’t come with sigpatches, because they’re mostly used for piracy, and ReSwitched is against piracy
You can add sigpatches to Atmosphere pretty easily though

Ah, I see why.

This is very nice, actually. Nervous to try, but awesome. Are there other things we could possibly change with this?

Replacing system file is the only way. LayeredFS won't work with these system titles, even I tried fsmitm.flag and boot2.flag .

Oh no no no, I know. I mean't like other than fonts, sorry for the misunderstanding.

i...is that...is that really fucking comic sans I see there
what fine taste you have

 

[XorTroll]

Always keep in mind that writing to NAND is dangerous, and even morer with NCAs!

 

[Paulsar99]

That looks really cool but also too damn risky just for the sake of being able to change the default fonts.

 

[Essasetic]

I'll wait till Atmosphere releases their version of EmuNAND to try this. Seems too risky at this point of what's only a theming option.

fsmitm does work, you just need to enable it for the shared database services.

For those who would wanna try it:

• Create an empty file at sd:/atmosphere/titles/0100000000000039/flags/fsmitm.flag
  
• Copy your custom font encoded earlier with bftffutil at sd:/atmosphere/titles/0100000000000811/romfs/nintendo_udsg-r_std_003.bfttf

So this basically removed the risk of bricking?

EDIT: Got it working but the file path for the font is actually "0100000000000811". Apart from that everything was right and I got my font of choice working on my switch. Thanks

Indeed I made a typo, a 0 is missing, thanks for that i'll edit the message.
