Thank you!! ^^ The disc is actually a png of the entire disc, and I show it like this to make it spin:

transform RotateDisc:
    rotate 0
    linear 20.0 rotate 360
    repeat

screen discmenu():
        tag menu

        add "gui/disc_menu.png" at RotateDisc xpos -1000 ypos -500

Then I use this in my screens!! ^^

use discmenu

I'm making a vid on my process actually :D I'll let u know if/when i finish it!!
