So I have a Vita with 3.60 Ensō and currently a 256GB SD2Vita setup. However I want more storage and I've seen in a number of places the maximum storage capacity SD2Vita supports is 256GB, but I'm not sure if that is only because 256GB Cards were the largest commercially available at the time or it's an actual limitation. If it's a limitation and it's a software limitation is there a way around it?
