I've recently upgraded to Gen D2 in order to play some of the newer PSP games, and I was wondering if anyone knew what effect the "On the Fly" decrypting has on battery life? Is the game just decrypted once the first time it's loaded, or does the firmware have to constantly decrypt the game as you play? And if it is constantly decrypting it, does it make any difference to the battery life? I've noticed that my battery hasn't been lasting as long since I upgraded, but then again I've been playing more games so it's hard to tell!!
