    Just compared the image quality of a PSP Go to the Vita and was stunned at how much better the games look on the older machine. If it possible to render PSP games in the native resolution? I don't mind smaller screen real estate as long as that blur goes away.

    Actually, if you set the res to 2x original in PPSSPP, a lot of the games look a lot less blurry and lot more detailed.
    I believe Flow wanted to implement it in Adrenaline.

    Don't quote me on it tho.

    That's an option in adrenaline, just set the screen size to 1x.

    That would be absolutely awesome as given the Vita to PSP scaling is x 2 being able to set the native res twice as high would allow for visuals on par with the original hardware. Any links where he speaks on this please?

    Thanks. Will have to check that out once I update, nice list of features that have gone into this since the jump it seems:

    I said don't quote me on it.

    PPSSPP is a PSP emu for PC with ports to other platforms tho.

    You can also reply without being a lousy troll.

    Just search on the web for it.
    Like I said, I believe Flow said it somewhere.
    No need to be a twat.

    Apologies friend, I thought you were acting like a whiny lil bitch when all I did was politely ask you for a reference hence my "humorous" comment. Anyhoo, do you have any idea how time consuming it is to find any info on "the flow + 2x" on the net?

    He said a big surprise Will come on september. And celesteblu quoted with: native vita res for adrenaline!

    That's on Tweeter and the_flow never confirmed.

    No prob~
    Yup, hence I said I believe.
    Couldn't be arsed at that moment to check sources really.

    Hmm I do remember seeing that but wasn't what I remembered.
    Was earlier then that announcement.

    Interesting, thanks for that. Lets see what kicks.

    All good my man, thanks for your input.


    I've just updated my Adrenaline install to the latest version, thoughts:

    The new easy installer is superb, literally does what it says on the tin with one click. Very impressive.
    New AA filter looks nice as does the smoothing, really takes the edge off.
    Being able to change the screen size is also a great bonus as 1.5x looks decent but 1x, whilst tiny, is razor sharp and really clean.

    Now I've only played around for a moment but I noticed FPS dips in stuff like Outrun 2006 straight away, if this common practice due to the overhead consumed by the filters? Also am I correct in thinking that Adrenaline runs sandboxed in full PSP mode? ie. the full speed and capabilities of the Vita are not accessible nor used in this framework currently.

    I forgot
    Adrenaline does run in PSP mode, and yes it's "sandboxed" since the "PSPemu" is mostly running on actual PSP hardware.

    Thanks, I had a feeling that was the case. I wonder how they are going to squeeze the overhead out for that upscaling then as things slow down with the current filters I feel and they are nowhere near as intense.

    An interpretation layer ala nintendont on the wii would be an excellent solution as it would unlock a higher clock speed and the vita gpu for the graphical clean up whilst allowing the psp hardware to focus on the game but I don't think the vita is cracked that wide yet, is it?

    Problem is, the GameCube on Wii (U) situation with Nintendon't actually isn't much; since the GCN and Wii use the exact same hardware (Hence why Dolphin emulates both at once) with differences in clock speeds, Nintendon't simply runs GameCube games as Wii programs. All it took afterwards was maintaining compatibility with troublesome games.

    The PSP and Vita however use completely different architectures; MIPS vs. ARM. It's not as easy as interpreting a PSP program as a Vita one. The Vita was only able to get away with it because, similar to the PS3, it has specific hardware essentially made for running PSP software; hence the "sandbox" effect we've had here.

    Granted, you could likely make the games run at higher resolutions on the Vita due to the hardware improvements, but that's about it. And, as we're seeing, that will/have taken extensive work. If we can make it happen, though, without sacrificing game compatibility or speed, it would be a fantastic alternative to PPSSPP.

    Thanks for clarifying that. Seems that porting ppsspp across to run natively on the vita side of things is the way too go as it sports some very optimised code that knocks it out of the park on lesser hardware than the vita plus the devs seem pretty amenable to new platforms. How come that's never been attempted as the sandbox elements seem to render all meaningful mods to the wrapper a moot point due its limited access and overhead issues.

    It's not that simple. We hardly even have fullspeed SNES emulation, and don't exactly have the benefits of many mature APIs like the other platforms do; how do you expect this to go over well? By the same logic, we'd have a fully working DS emulator as well on the Vita, but we don't for a number of reasons.

    It's also incredibly redundant, seeing as the Vita's built-in PSP 'emulation' is still infinitely more compatible than competing emulation options (Like PPSSPP, which still has a ways to go), without the quirks that come with it (Audio desync issues that are especially prevalent in Project DIVA, missing graphics/sound, pure compatibility issues like MH Portable 3rd SD, etc.).

    Really, just waiting to see if Adrenaline DOES get a better internal resolution scaler is a far better solution to a not-very-prevalent problem than taking things to such an extreme.

    True, its good for what it is so I look forward to the improvements. PPSSPP would however be awesome if ported to the WiiU but that scene is even deader than here.

    Properly read it.
    Then you'll understand.
