PS Vita emulation progress

I accidentally managed to run the simplest sample that displays "Hello, PSP2 World!" in console. It's actually nothing...

Code:

Well, that was unexpected! Are there any known emulators for PSV (PSP2)?

This is good.

There aren't any images of games anyway.

hm... how close is the hardware of a psvita to ps3? (this is probably a rly retarded question, but its interesting that psvita samples (1) run on rpcs3)

Like ps2 to ps3? Different architecture (arm vs cell), os and, well, almost everything else (though many psn/sonylibs-related stuff could be unified in some way)?

has ARMv7 something to do with PSvita emulation, or is it part of the ps3 emulation?

So is the final goal here to some day run commercial Vita games? Is the Vita OS similar enough to the PS3 one that it makes sense to do this in rpcs3? Like does it have similar APIs? Or is it purely done this way to in theory allow for cross play games or whatever?

Basically, why is Vita emulation/homebrew developemet testing tool/debugger/whatever part of rpcs3, if it even is?
Asus N55SF, i7-2670QM (~2,8 ghz under typical load), GeForce GT 555M (only OpenGL)

I just don't think that integrating vita emulation in rpcs3 is good idea (if totally different codebases). Why not separate emulator for it?

(and even if we had full working vita emulation it's still would be sort of useless as there is no way to back up isos or something. Only like writing simple homebrew that wouldn't run on Vita anyway until it gets hacked which may be in 1 year or 2 or never).
