Posting here just for the higher visability. I would like to buy spare SD cards from my stern spike 2 games Rush / Mando, and also to have a few for when friends games need it. Finding 8GB and 16GB to be kinda hard to find. Wondering if the original image is on a 8GB or 16GB and I purchase a 32GB if the image will automatically adjust for the capacity? And do I need to buy a certain type / brand? Stern just says class 10.
