Hello, I'm new about this so I have a couple of questions related to this topic! I want to use a AZ save game into a OR rom so, I was thinking about the team Magma-Aqua appearences (It happens even before 1st gym) Do they do event flags? Are unmatched event flags checked by nintendo/gamefreak when playing online? I'm just trying to have the more possible legal save game. Thanks! Any other info (or link) about event flags and how to set them on Pkhex would be very helpful.
