Most aren't, that is why launch titles are nowhere as impressive as games launched later on. I already addressed this. Uncharted GA isn't a port on a technical level because they never released it on a PS3 but at the same token they never had a firm target or hardware to hammer down so even in their post mortem they talk about the compromises they made and how they would have been able to do better given more time and resources.
It doesn't change the fact that they really did make this on an engine that was running on a PS3 and down graded for assumed specs.
Nothing of what you said here refutes what you quoted.
Hardware engineers are not game devs. Hardware engineers for Nintendo follow in a trend left by Gunpei Yokoi so they never push the edge on leading tech and the devs conform to the hardware after it is designed.
EDIT: Just to refresh your memory, this was in the post you dismissed earlier
And again to reiterate, we are both speaking facts but you are using semantics to obscure the fact that they admittedly didn't work on Vita final hardware or solid specs for most of the development of a title and you used a launch game to refute the ability of games on Vita being native res. All of this is a silly argument to begin with because of the reasons I mentioned before and also the sheer fact that most games on the Vita actually hit native res. The few you can list most likely were designed without the resolution target (or even the vita itself) in mind.
I don't know why you are still discussing with him about a launch game. He just won't get it.
