Hey, In another post I’ve started with some Icons. here
So this time I want to redesign some Interface parts of the Gameshell with the look of an OP-1 from teenage engeneering. From time to time I will update these Designs. (I got my GS last week, so I try figure out how to change the background ect.)
Hope you like it

Installation:
Download a client like FileZilla connect your GS with following Account:
192.168. (ending is different) just look into the tinycloud app… User: cpi PW:cpi Port:22
Then download my dropbox files and copy and paste the appicons into
home/launcher/skin/default/Menu/Gameshell <---- Homescreen Icons
home/launcher/skin/default/Menu/Gameshell/20_Retro Games <---- Emulator Icons
Then Go back to and copy and paste all the UI Elements to these folders
home/launcher/skin/default/sys.py/footbar_icons
home/launcher/skin/default/sys.py/icons
home/launcher/skin/default/sys.py/titlebar_icons
And for the bg colors and loading screens go to
home/launcher/sys.py/UI <---- place the skin_manager.py here
home/launcher/sys.py/gameshell/wallpaper <---- place the loading, gameover ect. here
Incredible! Love the OP-1. Probably what took me here. (PICO8, OP-1, CloCkWorKPI)
