Looking through the categories, i did see a couple for Area x. They are presently separated as blue and red. Not familiar with this, i have to ask...what defines each? What would we need to submit for a valid run of area x red or blue?

Debating on which and what system to run this on. PC emulation would be convenient, naturally. Is RetroArch running a given core considered a valid emulation mode for submitting runs? If there are specific settings or cores I should run, what would fall under that?
