So as most R4 users are still waiting for a patch for a certain racing game, it never dawned on me on how games with piracy protection could detect flashcarts. Most of us have probably experienced various forms of protection, like 'traps' in certain parts of the game (Chrono Trigger DS), unable to save (GTA:CW), or even unable to boot completely. To the DS console, isn't a flashcart a normal game card to them? I'm certain those games have lines of codes to check something, but what, and how exactly? As for bypassing the protection, we have cheats which is patched into the game ROM which allows the piracy check to be bypassed or circumvented. I have a rough idea on how it works, but it's definitely better to know more. Answering these might require a degree of technicality but it would be very helpful if you guys could get down and dirty.
