It has been confirmed numerous times that Lair works via Remote Play on the PlayStation Portable. We should note, however, that it isn’t the PSP hardware that is running the game; while Sony’s handheld controls the action, the processing power itself is actually handled by the PlayStation 3.
The only downside to the PSP mock version of Lair is that it simply doesn’t implement the full experience. Dragons are controllable with the PSP’s handle, but R2 or L2 do not work—so landing becomes impossible.
Warhawk and Ghost Recon Advanced Warfighter 2 have both been tried on Remote Play, but failed to function as adequately as Factor 5’s Dragon-slaying epic.
Even though Lair isn’t fully compatible on the handheld, the possibilities of such a discovery are endless. Imagine Final Fantasy XIII on the PSP. Even if not all games are supported, the prospect remains interesting.
