PS Vita Compatibility
Despite not being in the official compatibility list, Ape Escape: On The Loose can be played on the PS Vita. To do this, the user must first download the game to the PS3. From there, go to Content Transfer on the PS Vita and select the game for transfer. Once complete, the game will show up on the Vita's menu.
EDIT : The game have since been updated to be officialy compatible with the PS Vita.
