I recently got my ps4 jailbroken from a nearby console repair shop , every thing works fine i asked that guy to download 6 games he did all of them and they are working perfectly fine . He jailbreaked with the Blue ray disc method as far as i know because there is a unmarked BR-D disc in my ps4 . When i open the goldhen cheats for a particular game it shows no cheats found for this game. How do i get cheats for games like gta v , rdr 2 , mk11 . And from where and how do i install new games in form of .pkg file , do j need a hard drive or some sort of usb drive or somehow i can just paste the .pkg file to my ps4 from my laptop. Also suggest legit websites to download the game packages
