This step can take anywhere from 15 minutes to over an hour depending on how fast your PC is.Let your computer generate the new DATA.CPK file with your mods.Tick the mods you wish to install and hit ‘Build’.Make sure you keep the tick on “Use Compression”.Click Settings and point to your decrypted CPK file.Open Mod Compendium and select Persona 4 Golden in the top left selector.You may need to copy some mods to your Mod Compendium folder since not all of the aforementioned mods are included with it.Mod Compendium is relatively simple to use but do note that building CPK files takes a while!
