About

KantOS is a theme ported for OnionOS, which is inspired by the Kanto region of Pokémon.

The concept design was first created by Tressley on muOS for the Anbernic handheld devices.

I was a huge fan of it, and I'd like to express my appreciation to Tressley for creating the theme and also giving me permission to port it to OnionOS which I have since heavily modified to suit the OnionOS architecture, and also included many of my own additions.

Credits

• Aemiii91 for letting me include their Dot-art by Yoshi-kun icon pack from the Onion Theme Repo
• Spriters-Resource for the Pokémon sprites
• Yuji Oshimoto for the 04b_03 font
• Pokemon Gen 1 Pallet Town OST used as BGM
  • Pokémon Black/White 2 for the Virbank City OST used as alternative BGM

Important Notes

• It is highly recommended to update your OnionOS to at least v4.3.1-1 or higher, as it removes the text-shadow effect that's present on earlier versions which is incompatible with the font used here (see the OnionOS Releases page or use the OTA feature within Apps on your Miyoo Mini)
• On the wifi configuration page, the font color of the highlighted item as well and the text in the keyboard pop-up when you go to enter a wifi password are both bugged, since those appear to be set at the system-level and isn't something I can change through the theme's config file
• In case you have any existing theme overrides, I recommend that you enable the battery percentage option with the following settings to replicate what's been set in the config file for the best UI experience:

Go to Apps > Tweaks > Appearance > Theme overrides > Battery Percentage

"Visible": set to "-" (the theme config will turn it on by default)
"Font family": set to 'Exo-2-Bold-Italic_Universal'
"Font size": 18 px
"Text alignment": Left
"Fixed position": off
"Horizontal/Vertical offset": both set to 0 or off

Download

Download this repository as a ZIP file (via the green <> Code button in the top-right > Download ZIP)

Alternatively, go to the Releases page and download the Source code (zip) file.

Installation

To install the default theme:

• Place the downloaded ZIP file into the Themes folder of your SD card
• Apply the theme by going to Apps > Themes

To install the minimal version:

• Extract the downloaded ZIP file
• Copy the images inside the minimal-alt folder
• Paste them into the skin folder to replace the existing images
• Place the entire theme folder into the Themes folder of your SD card and apply the theme

Changing the BGM

The default BGM is the Gen 1 Pallet Town OST, but the file for Virbank City OST has also been included.

• To change the BGM, go to the sound folder, rename the existing bgm.mp3 to something else, then rename the virbank city file to bgm.mp3
• Re-install the theme

You can include your own custom BGM by following the same instructions above with any MP3 file, however it's important that the audio sample rate is set to 48kHz or it will sound too fast/slow.

How is the minimal version different?

The base design of this theme is my own rendition which includes more overworld elements as menu icons.

The minimal version replaces the icons for Expert, Apps & Settings to match the same aesthetic as the original muOS theme for Anbernic.

Please see the next section which showcases both.
