Instructions
Download the TTmenu Skin Customizer ZIP file and unzip it to a convenient location.
Open "TTmenu Skin Customizer.exe" to launch the application.
Remove the SDHC or TF card from the top of the DSTT cartridge.
Insert the card into the end of the SDHC/TF USB adapter.
Insert the adapter into an open USB port on your computer.
Open "My Computer" from the desktop or Start menu.
Open the "Removable Disk" icon.
Open the "TTMENU" folder, "skin" folder and "default" folder. The "default" folder contains the 36 files that make up the DSTT skin.
Copy the contents of the "default" folder to a different location to create a backup.
Return to TTmenu Skin Customizer and click "Open Skin" on the right side of the screen.
Navigate to the "default" on the "Removable Disk" and select the "skin.ini" file. The application combines the image files to show a preview of the skin.
Open a graphic editing tool such as MSPaint or Adobe Photoshop. Open each file and customize as necessary. Do not change the filenames or resize the images.
Click "Reload Skin" in the Customizer to update the preview with your changes.
Right-click the "Safely Remove Hardware" icon on the Start menu and select the "Removable Disk."
Disconnect the USB adapter from the computer and reinsert the memory card into the DSTT cartridge.
Insert the cartridge into your Nintendo DS system and turn it on. The new skin will be automatically applied.
