** YOU NEED TO USE A HIGH QUALITY HIGH SPEED MicroSD Card to do the update for your firmware / kernel.  Using a low quality / slow card can result in bricking your cartridge.  THIS UPDATE IS ONLY NEEDED IF YOUR CARD DOES NOT WORK ON YOUR SYSTEM. Please note that your console must have NEW BATTERIES or be plugged in and charging if you plan to do the update.  This version will also make it compatible with the Analogue Pocket.

IF YOU DO NOT NEED TO UPDATE and your card is WORKING FINE - DO NOT Update as if done incorrectly due to users did not read the notice and bricked their card.
