* 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.
