Back when USB loading was the new thing, I was playing MP1 through DVD in normal dfficulty. Then I thought, why not play through USB? It'd be faster and easier! So I got a USB-ready version (would have replaced the .dol myself using my DVD, but back then I wasn't that much in the scene), I played, it was all fine. But then I went to fight the final boss, and surprise! it was friggin hard, more than it should. So I started the game through DVD to check the settings, and the difficulty had magically changed to Veteran! I tried to beat the game anyway, but after many days of trying I just gave up and used an infinite health cheat to beat it. No fun. So has anyone had this problem? Does this happen with Metroid Prime Trilogy? Or is there any cheat code to chage the difficlt on the game?
