Oh if r3 allows you to alter the original 21 then that's perfect for you. The dumping kernal/adding games process is actually very streamlined with this program. You can add all your games first THEN install the drivers and the kernal. Like if I remember correctly after you get the games on there and hit the synchronize button the program walks you through everything with the driver installation and kernal dump.That's what I'm gonna do when I get the chance to dump the kernel and flash it, but as far as the drivers go, I plug it in first then install them with Hackchi
