 Below here is a Windows sprite editor tool I programmed that can be used to create sprites and copy that sprite data to the clipboard buffer. I use this for some of the example in this repo. I might rewrite it for Raylib in the future. The spritedata copied in the clipboard by the sprite tool are inside a array. It uses the c64 palette or the db32 palette. The color values can be found online.
 
+The editor is based on the Pico8 sprite and map editor.
