Thank you so much for the reply! I have a question. Since I have now submitted a score with 2 cores, doesn't that mean I can no longer strive to improve my score with 1 core because only the best/highest scoring submission for the same hardware gets points?
Indeed. It does not give me the option to set number of active cores . Also according to the rules, hardware unlocked cores need to be submitted under its original name. Prime is a nearly auto submission anyway, not much to change.
