Editing PS3 and PSVita Cross Functions

=Description=
Ps3 firmware added support to PSVita in firmware 4.00

This page pretends to document all the functions related in the PS3 side... for the PSVita side see http://www.vitadevwiki.com/

==Main Functions==

===PSVita Remote play===
A flag for ATTRIBUTE inside PARAM.SFO was added to enable remote play. See [[PARAM.SFO]] and [[Remote Play]] pages 

===PSVita Cross play===
PS VITA used as controller but not directly SFO related. (PS3 FW min 4.20 with PS VITA FW min 1.80:)

===PSVita System Application Utility===
Backups "some?" contents from PSVita memory into PS3 internall HDD, in path: '''dev_hdd0/home/0000000x/psp2_backup/'''
*Notes/Speculation:
**psp2 is the codename of PSvita, this contents are "shared/exported/imported" between PS3 and PSvita
**Can be also found without ps vita, generated folder and displayed :e.g. with PS vita pkg
**"psp" folder display "psp/other", "system" folder don t seems to expect .pkg. 
**Trophy PS3-PS vita for possible similar user path.
**icon added to display vita content in XMB{{Icon_content_psvita}}

'''Gamesaves'''
*Are stored as part of the backup utility ? (so no accesibles by ps3)
*Is posible to import export PS1 and PSP gamesaves back and forth ? (if so, is needed a short explain and a link to [[Game Saves]] page)
