Ok, just mounted flash0,0 using usb-SSS, and found gameboot.pmf in vsh/resource. I downloaded the Super Gameboot pack, and just wondering, is it safe to just copy over the gameboot straight to flash (obviously will make a backup of original)?
EDIT: tried it, realised USB-SSS mounts as ReadOnly. So did it using recovery mode, worked great
