Loadiine IS cafiine.
It redirects access to SD card.
If you want to mod your games, just replace the file on the SD card, or create new folder in a "updates" folder in your game's folder.
example :
game's name [TitleID]/updates/My mod/ content+meta+code here
then in loadiine, enable the individual game settings, and select the "my mod" update to replace the files on the fly.
