* Can now boot stage2 (in safe block mode) if holding L-Shoulder +
R-Shoulder + A + B + DPAD Up on boot. This allows using built in stage2
usb update mode for "bootleg" style N-Cards that have Xulumenu
installed.
* This button combo will not do anything for regular N-Card users as
they already have a proper stage2 section on nand and it will always end
up booting to USB update mode with this button combo before xulumenu can
boot.
