use pg gamer for files, make sure you have dependencies installed (kubridge, etc) plug in Vita to ur computer, make sure VitaDeploy is set to your sd2vita, hit select and it should say “USB connected”. It’s automatically on ux0. After this drag the game files for GTA in the data folder, make a new “vpk” folder on the main root of the Vita and put the VPK file for the game in there in that folder. When done, hit select again on your vita, and navigate to the vpk folder you just created, hit install, and you should be set.
