IS THERE A VITA VVSSPP

[pspvita@flagship]

i have already donated and will keep donating and i just want to know from you, is there a Vita Emulator.
I would request the Developers to please develop a Vita Emulator pleeease.
Some game in Vita are really good. My vita device runs them all but i find the screen on PS Vita to be really small.
I am getting older every day and i wish to request: Please develop a Vita emulator for PC.
