We thought life was good with the possibility to host HENkaku on our phones and access it from within our local network. We knew nothing, Jon Snow. Developer xyz, part of Team Molecule, is working on a self-contained version of HENkaku that just runs on the PS Vita, without any network access (in other words this also works with the Wifi turned off).
The teaser video below was shared by Yifanlu a few hours ago on twitter.
Of course this is strictly for people running a PS Vita 3.60, and will not be of help to the poor souls who upgraded to PS Vita firmware 3.61.
Update: more details on the inner workings from the HENkaku IRC channel, thanks to StepS:
[22:29:48] <xyz> enjoy https://usercontent.irccloud-cdn.com/fi ... G_0378.MP4
[22:32:24] <xyz> I'll provide a vpk that will do all setup
[22:32:33] <xyz> you don't have to enter any email account manually
[22:32:47] <xyz> the vpk will add an account to email app which will have 1 email in inbox
[22:33:35] <xyz> soon(tm)
[22:52:11] <xy2_> xyz: does it also support initial install
[22:52:22] <xyz> no
[22:53:30] <xyz> there are several complications with that and ultimately I don't see the need for it to do initial install
[22:53:50] <xyz> don't worry about the details
[22:54:13] <xyz> you will just launch the installer vpk when you have internet and then it will download newest payload for email
[23:29:55] <dkabot> I wonder if someone will try editing the name of the email/acct
[23:30:12] <dkabot> Just like "Free $1,000,000! Open to claim!"
[23:30:33] <xyz> actually you cannot just forward this mail and have it work on another person's vita
[23:30:47] <xyz> it also uses some data from filesystem that gets installed by the installer vpk
[23:30:48] <dkabot> xyz: I meant editing it in db, if at all possible
[23:31:03] <dkabot> Just for basic image gags, not to forward it
[23:31:05] <xyz> yeah sure
[23:31:10] <xyz> it's just sqlite
