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.

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 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

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 alt version:

Extract the downloaded ZIP file
Copy the images instead the alt-skin folder
Past them into the skin folder to replace the existing ones
Place the entire folder into the Themes folder of your SD card and apply the theme

How is the alt version different?

The original design is based off the muOS theme which has the 3 primary menus as buildings, while the remaining menus are more minimal 'material' icons.

The alt version replaces the icons for Expert, Apps & Settings to overworld elements, in order to match the aesthetic of the buildings.
