Just to remind you.

1)
change the folder name to themexx.
replace the x with a number you don't have in your themes folder
Folder 1 through 9 has to be 0number, for example:01, 05 and 09.

2)
futher: there is a maximum of 12 themes in the themes folder 
and on the screen where can be choosen for either moonshell or a game
the background can be changed by pressing sellect.

When there are more than 1 themes you go around all the themes, even if there aren't 12.
After theme 12 there comes an automatic theme which changes every month( 12 themes, 12 months xD)


Thanks for downloading and enjoy
