---

A repository with dozens of custom Nintendo 3DS system fonts to personalize your console! You can also convert your own fonts using GitHub Actions (based on the guide by AromaKitsune).

Custom firmware (CFW) is required to install custom fonts. You can setup custom firmware with this guide.

Note

Some games use the system font to display text in-game. In certain games this means your custom font will show up, and in others, the text may appear corrupted or not show up at all. A list of games that are affected can be found at compatibility.md.

Caution

Custom fonts are safe as long as you have Boot9Strap and GodMode9 installed. Uninstalling CFW while having a custom font installed will brick your console. It is highly recommended that you make a NAND backup before modifying system files.

Installing Custom Fonts

Important

Installing custom system fonts with FBI is not recommended. Use GodMode9 by following the steps below.

1. Download SytemFont.cia file and transfer it to your 3DS' (micro)SD Card via FTP or an SD Card reader.
2. Hold Start while powering on your 3DS. Select GodMode9 if prompted.
3. Select the [0:] SDCARD (***) directory.
4. Navigate to where you saved your SystemFont.cia file, then select it.
5. Select CIA image options... then Install game image.
6. Press A to unlock SysNAND then follow the prompts. Press A after the font is installed, then press it again.
7. Press Start to reboot to the HOME Menu.

Your custom font should be applied. If you get a crash/error message instead, this means your font is not compatible and you will need to restore the default system font.

Uninstalling Custom Fonts

1. Download the original SystemFont.cia
2. Transfer the file to your 3DS' (micro)SD Card via FTP or an SD Card reader.
3. Hold Start while powering on your 3DS. Select GodMode9 if prompted.
4. Select the [0:] SDCARD (***) directory.
5. Navigate to where you saved the orignal SystemFont.cia file, then select it.
6. Select CIA image options... then Install game image.
7. Press A to unlock SysNAND then follow the prompts. Press A after the font is installed, then press it again.
8. Press Start to reboot to the HOME Menu.

The orignal system font has been restored.

Converting Your Own Fonts

You can convert any compatible font file to an installable SystemFont.cia in as little as ~50 seconds. You have two ways of doing so, GitHub Actions or a Powershell script. GitHub Actions works on any device from a web browser but requires a GitHub account and a direct URL to a font. The Powershell script only requires a Windows machine and lets you convert any font you have (.otf, .ttf, or installed fonts).

Both methods are based on the guide written by AromaKitsune and use the same tools and scripts. None of the tools used are made by me, you can find more info about them below.

Important

Neither of these guides are done yet, they are just placeholders.

2. Go to actions

Special Thanks

First and foremost, this repository would not exist without the hard work of AromaKitsune. Huge shoutout to them for making their original guide on how to make custom fonts (found here) which was used as the basis to make the workflow.

I'd also like to give thanks to OctoRuler, a member of the Custom 3DS Assets Discord server, for cheering me on and helping with the compatibility list.
