@annieminnie I think from what cybergeisha said, you need to have a KStar kollection at the same position as the diamond kollection (i.e. 0/8 for Kstar kollection and 0/8 for diamond kollection).
1. Using whatever emulator you have, go into you KStar kollection and search for how many Kstars it costs to play (for example search 30)
2. When found, go to the diamond kollection and refine your search with the diamond amount (for example, 12)
3. When found, change diamond amount to "0" and spin.
4. Repeat the process for each spin
