Im not sure if the files work myself but they are from the same source who leaked the Monster Hunter Freedom Unite.
But this time, theres a VIDEO the exploit in ACTION AND The files to go with it! He says they may or may not work for your device, but hopefully someone who knows what theyre doing can fix the problem!
His hack allows people to play PSP ISOs and PSX Eboots on the Vita through a hack on the PSP EMU Kernel.
The game used is Urbanix and its a Mini that costs about 3$ on the US PSN.
I'm trying to do this, but there is one main problem. You had to download Urbanix onto your Vita before this was released. I have a 1.61 OFW on the Vita and an OFW PS3. I bought the game through the PS3 but cannot transfer the game to the Vita without updating it's firmware to 1.81. Is there a way to transfer the game to the Vita without the update?
EDIT: Updated to 1.81 and moved Urbanix to Vita, but it won't work now because on 1.81 the Content Manager doesn't allow the savefile exploit to be transfered to the memory stick. We need proper exploit files for 1.81.
