Wonder if they are gonna do something about the controls? Retribution was built around an auto aim system using the dpad for precision aiming.
Well, for one thing, it's a ROM release, not a remake. Probably you're aware, but if not, Sony has recently been addressing the backwards-compatibility issue (although not really through backwards-compatibility, Sony is instead introducing new PS Classics games to buy PS1,2& PSP games digitally,) and so this Resistance Retribution release is in all likelihood part of that.
Second, I don't think Resistance Retribution ever had an official "dual analog patch", but I do believe that PS Vita had a feature with backwards-compatible PSP games that the right analog stick could be mapped to work for controller button actions, and
Resistance Retribution on PSP does work that way there. So I assume it'd be the same here.
Third, I don't know if I'd call it "auto-aim"... the game had a lock-on system, as it was built on the Syphon Filter framework. Yes, that made aiming a lot easier (and then you could dial it in for precision) but if I remember right you still had to manage motion and trajectory for accuracy of shots, plus it had stop-and-pop mechanics. So less "auto-aim", more auto-directionality. Maybe that's the same thing in some eyes, I guess I'm just specific about it because I actually always liked the Syphon Filter shooting systems. (The "skill-based accuracy" of gunplay in modern games is really inauthentic IMO, with all the bunnyhopping and aim-down-sights-in-a-sprint nonsense. Even though players feel totally in control on the battlefield with their analog aiming systems I feel in some ways SF's ruleset for shooting percentages was more how combat games should be.) Those unusual types of mechanics thrived on PSP for a while since the limited controller gave no option but to try new things, and I feel like modern games are missing out because they all feel there's a "right way" to make a battle game. I wish Syphon Filter aiming was still a thing in some games, even if it could be called "auto-aiming"...
