Not sure I've understood properly.
If I update now, can I get access to PSP homebrew/ISOs on 3.60, in addition to this new hack?
I've not touched my Vita in a while, but I know it's on an older firmware where I can run the PSP games I own that aren't on PSN, although I didn't set it up properly yet.
Edit: I said "games" but it's really just OutRun 2006. Why on earth is that not on PSN..
Until it's released, we can't say anything for sure. Here's how I understand it:
The 3.60 update "fixed" (read: broke) the exploit that allowed us to run PSP ISOS with a loader like ARK or TNV.
What this hack does is, basically, grant you full access to the Vita's software, so you can install things as if they were official. It's a temporary exploit that you have to rerun when you turn off your console, like the non-permanent PSP exploits or the userland Wii U exploit we currently have.
From what I can gather, at the moment we'll only have a handful of homebrew emulators that have already been ported for this exploit. I don't know if the PSP ISO issue could be solved with this exploit. It could potentially be solved, and I sure hope so, because that's my main interest in this stuff. A proper and quality implementation of the PSX emulator would also be great.
But, as I said, at the moment we only have a handful of emulators. If you don't want to lose the ability to run PSP ISOs, don't update just yet. Wait a bit to see how it all develops. Otherwise, go ahead and update, since HENkaku only supports 3.60.
Edit: As a PSA before locking my Vita to 3.60, what games do you guys consider to be essential for the platform, so I can buy/download them ASAP? I'll be glad to hear your suggestions!
