How to use

NSO Icons

Important

You must download the NSO Icon Cache from the settings page before they will be available. They aren't shipped with the application.

• NSO Icon components are (usually) split into 3 parts: a frame, a character, and a background. Use the related button from the main page to browse the available icon parts (e.g. Frame lets your browse available frames).
• Once you've created the icon, use Apply to User and it will be automatically applied to the selected user. This change won't be immediately visible everywhere on the switch; just how it works.

NSO Icon Cache

• The icon cache contains all the NSO icon components. It must be downloaded in settings before they are available. This can take awhile the first time so be patient.
• You can check for updates to the icon cache from settings. If new icons are available, you can downloaded the new cache and update your local copy if desired.
• The cache is kept in sdmc:/avatars/nso-icons-main.
• For speed, existing files aren't overwritten when updating the cache. If you have an issue, you can use Overwrite Existing Files During Update in settings to toggle this behavior.
• Icon cache location: https://github.com/henry-debruin/nso-icons

Custom Images

• Place any custom images (PNG or JPG) into sdmc:/avatars/ so they will be found. Sizing your images to 256x256 would be best, but incorrectly sized images will be resized automatically. This will likely not work well if the image width/height aren't equal.
• Select Custom Images on the main screen if you want to use the image as your avatar directly.
• You can also select Custom Images from one of the Icon Component lists (e.g. Character, Frame, or Background) if you want to use your image together with parts from the NSO Icon Cache to build your avatar.

How to build

Requirements

• devkitPro
• CMake

Docker

• compose.yaml is provided which can be used with Docker as a build environment already containing the necessary requirements

Build

git clone --recursive https://github.com/dslatt/nso-icon-tool/
cd nso-icon-tool
cmake -B build_switch -DPLATFORM_SWITCH=ON
make -C build_switch nso-icon-tool.nro -j$(nproc)

or

git clone --recursive https://github.com/dslatt/nso-icon-tool/
cd nso-icon-tool
./proj_build.sh

Using MSYS2

You need a working DevKitPro installation and then install the packages:

MingW64:

pacman -Syuu git make cmake mingw-w64-x86_64-gcc switch-cmake libnx switch-dev switch-glfw switch-curl switch-libzstd switch-liblzma switch-lz4 switch-bzip2 switch-xxhash

MSYS

pacman -Syuu git make cmake gcc switch-cmake libnx switch-dev switch-glfw switch-curl switch-libzstd switch-liblzma switch-lz4 switch-bzip2 switch-xxhash

The commands to build are:

cd ~
rm -rf ~/nso-icon-tool
git clone --recursive https://github.com/dslatt/nso-icon-tool
cd ~/nso-icon-tool
./proj_build.sh

Special Thanks

• Special thanks to henry-debruin and simon-debruin for creating nso-icons. There's no way this would have been made without your work pulling all the icons together that way!
• Thanks to delta for creating nso-applet-api which is used to create the icon dump
• Also, thanks to mydough for helping me find the right people to credit for the icon cache
