It was brought to my attention that there are some other differences between the ps4 and psp versions of the game and wanted to document them here:

psp:

• slower menus

• runs at 30 fps

• no friendship items

ps4:

• faster menus (2 times faster than psp)

• runs at 60 fps (at least that is what it seems like for the menus, other parts of the game are unaffected).

• all friendship items are given to the player at the start of the game

If any other differences are brought to my attention, I will add them post haste
