“ To change the icon/livearea bg, put those file in
ur0:/appmeta/yourbasegametitleid/icon0.png (if your base game's icon0 file has a .dds extension u have to change the icon0.png to icon0.dds)
For other 3 file put them in ur0:/appmeta/yourbasegametitleid/livearea/contents/ (reboot your vita and u should see new icons now)
If you want to change your basegame name:
Download/Install sqllitebrowser (google it)
Download your app.db from ur0:/shell/db/ by ftp and open it up in sqllitebrowser
Go to browse data tab and in the table dropdown select tbl_appinfo_icon
You should see a list, find your basegame name and click on the title tab, write Adrenaline in the right box and click apply.
After clicking apply in the upper tab of sqllitebrowser click write changes and upload it back to your ur0:/shell/db/ by ftp and then reboot, your are done~“ - Written by u/Kotagami
