About

KantOS is a theme ported for OnionOS, which is inspired by the Kanto region of Pokémon. It was built using a combination of custom and original sprites from the GBA Pokémon games.

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.

I have since heavily modified it to suit the vastly-different OnionOS architecture, and have included many of my own additions to the theme.

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 the Apps on your Miyoo Mini)
On the wifi configuration page, the font color of the highlighted item as well as the font 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 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

You can find the latest ZIP file on the Releases page.

Installation

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

What is the difference between `Ver. A` and `Ver. B`?

Ver. A is the original design concept based off the muOS theme which has the 3 primary menus as buildings, while the remaining menus are minimal icons.

Ver. B is a more overworld-focused theme, and has transformed the 3 aforementioned minimal icons to overworld variants.
