We just assumed that the updated Remote Play feature-set would provide the potential to play all PS3 games via the Vita. Unfortunately, that's not the case, as only games designed with the feature in mind will be supported.
"Yesterday, the demo that I showed using Killzone 3 was customised," Yoshida told GameInformer.
"It was meant as a technical demo and we haven't even finished the utility of the Remote Play that's really, really nice to support higher resolution screens on PS Vita, and the mapping of controls like R3, R2, L2 buttons using the backtouch panel.
"So as soon as we complete the development of those utilities, we will release the utility to PS3 developers so that they can check if their games work with the utility or they may have to do some additional work, because the Remote Play takes some additional memory and CPU time out of PS3 games. So some games that really utilise the PS3 capabilities may not work, so we'll see."
