A wallpaper I made using some art I did to practice pixel art.
Supposed to be a reimagining of Kowloon Walled City as its the setting for a game I'm hoping to make.
to add a wallpaper (some of this might already exist) to picotron under appdata create a folder called system, and under that create a folder called wallpapers, and save it there.
If you want to continue accessing the base wallpapers copy them to the new appdata folder.
