Hello, This tutorial will allow you to use multiple accounts on a single memcard. You will need the PSN creditentials of each account you 'add', as well as HENkaku. First off, note that this is glorified account sharing. If you want to do the much simpler method of simply playing the games of your friend, here's a comprehensive guide: Step 1: ask friend for account. Step 2: format your Vita. Step 3: enjoy new account and free games. The advantage of this method is that you can use multiple 'accounts' at a time on the same Vita. Do not do this if you have no idea what you are doing! The concept of this method is store files belonging to multiple accounts on a single memory card, hence allowing swap without formatting. The first thing you want to do is backup these four files: vd0:registry/system.dreg vd0:registry/system.ireg ux0:id.dat tm0:npdrm/act.dat You can do this over FTP. You might be puzzled at how some of those partitions don't show up; this is because molecularShell is sandboxed by default to only allow write to memcard partitions (as in, it hides the others). You can simply type the name of the partition you want to access in your FTP client, and it will show up. The next thing you want to do is format the file id.dat in order to unslave the memory card: this is important in order to be able to use HENkaku later. Now do a safe mode reboot (POWER + PS + R). Do a system format. Go through the initial setup inputting your extra account creditentials, then install HENkaku, activate the Vita and dump your new act.dat. Finally, restore the old act.dat and reboot your vita. Keep both act.dats in a safe place. For extra accounts, follow the same procedure, and reformat the secondary memcard each time. To switch accounts, use molecularShell to move the act.dat, registry.dreg and .ireg, and id.dat of the account you wish to use (I recommend using a non-sandboxed mS build for this as you won't be dependant on FTP this way) and reboot your vita.
