I've been out of gbatemp for a while, but from my understanding to connect online you need to personally dump identical copies of a game you want to get some sort of code? Did I misunderstand that or has it changed? I searched this up on gbatemp but had a hard time understanding how it works? Can someone explain it to me in layman's terms? I really want to be able to play my roms online without having the chance of having a friend's copy banned.
