My memory card died a long time ago, a 64gb we all know the story. Since then it has been sitting on my table unable to be played. I don't know why it took so long, but it occurred to me last night I could downgrade to my old memory card, so after serveral hours searching I found it. A 4gb card.
So today I've checked my vita to see what I can reasonably put on the card. Under 2gb of PSP games, under 1gb of PlayStation games. Vita is not showing me a total despite there clearly being stuff in the folder, and at a glance I can't tell if it's save data, DLC, or full games. Saying that under the "Other" section, in "System Use" there 52gb I can't touch. Now normally I know system use would be stuff like OS updates, but there is no way I've downloaded 52gb of OS updates.
