Tested and working with Uno US (signed with fake_np) as the base game.
From the readme:
Use sign_np (I suggest fake_np) to sign ARK2.ISO with your base game.
Transfer ARK_12345 save to your Vita.
For the base game I suggest cloning the same game you used for VHBL.
The base game must NOT be a crappy minis or 3.18 exploit game.
When you start the signed ARK2.ISO you should see a gray screen,
then a white screen (first "stage" of the exploit passed),
then a green screen (second "stage" of the exploit passed),
then you should see some text from ARK running the menu, etc.
Once in a while the kexploit attempt will throw an error, if so, a hard reset is required, otherwise launching games again will freeze.
A beer or two would be greatly appreciated.
