Memory Card Initialization
It turns out that memory card supports standard Memory Stick protocol (TPC).
Msif driver allows to read and write single values on memory card according to the (TPC) protocol.
It can also read and write chunks of data from memory card using (TPC) protocol.
It is still not confirmed, however based on some findings in Msif driver, it is hypothesized that Vita`s memory card is simply new generation of memory stick with additional auth layer.
If auth layer can be faked, it could probably be possible to use usual memory stick with Vita.
