Instructions
Download the skin you want to install onto your Nintendo DS. MoonShell skins can be found by performing an Internet search for MoonShell skins (see Resources). Download the file and save it to your game system. Extract the file by tapping on the icon twice.
Create a new folder entitled "/moonshl/skin."
Launch the MoonShell program, then select "Options" from the menu. Within this sub-menu choose the option that allows you to prevent the "Moonshl Directory" from being hidden.
Exit MoonShell and reboot your Nintendo DS system to allow the changes to take effect. Once the system has restarted, open MoonShell again.
Choose the "Open" option from the "Menu" bar and then select the file called "skin.ini," which will be located in the new folder you created for the downloaded skin. The skin will then load into MoonShell.
