1. Place contents of 'ALL' on your SD card root
2. In 'ALTS' folder, go through each character and place the alt you want on SD card root.
eg. ALTS\Bayonetta\ (I want the bayonetta 2 image, so open bayonetta 2 folder and place contents on SD card root)
ALTS\Corrin\ (I want female corrin's image, so open Female folder and place contents on SD card root)
3. REPEAT FOR EVERY CHARACTER IN ALTS FOLDER - Even ones you want the original image from, just use the original image in ALTS\Character
4. Regenerate cache
