Download the latest Repatch_ex kernel module from Github.
Using VitaShell, install the module into your main /tai/ folder
Some users will have this on ur0: and others will have it on ux0:, depending on how you configured your Vita when you set up Henkaku.
Open config.txt and add the following to the end (replacing ur0: with ux0: if you keep your tai plugins on the memory card):
*KERNEL
ur0:/tai/repatch_ex.skprx
Save the file, then reboot your Playstation Vita or Playstation TV.
Find your game's Title ID.
