Hello, I was just wondering how I can use emulators and homebrew stuff (mainly hte media-player) without a modchip. I tried the independance day exploit, but I could not get it to work (I downloaded the .NPO files, extracted them, changed the titles.DB files, then repackeged them into a X-Port file and sent it to my memory card). I used the slus_00220 for the TITLES.DB, and I pout the disk in, but it just loaded the game.
