[Definitive answer] PSP games resolution on PS Vita

I've not messed with this plugin much but after reading your post I'm thinking about giving it a whack now...

 

If you're talking about sharpscale, it does nothing useful for PSP games on a handheld Vita, unless you really want 1x native resolution without that extra frame of input lag. Shutting off bilinear in official settings on the unmodified original scaling also gives you a perfect 2x integer scale. Its only other use on handheld is to mess with PS1 scaling, which is beyond the scope of what I discussed.

 

(Thousand Arms..Legend of Legaia..The Expendables) Some games work correctly on the PS3 and VITA for ps1 and not pc emulators.

Within the Last year and a half, there was a processor speed option introduced into some pc emulators like pcsx (lr-pcsx also)..........that allows games like "Legend of Legaia" (power up animation) to work, if you turn that value up, but you can see its just workable, not really fixed. (Zanac x Zanac needed that processor option to work right, same for Alundra 2, not much else).

Price and Functionality and Updates.........that would be the Raspberry Pi4, for psp and ps1, and dreamcast...........however emulation has not outside of the pc, and on the pc. Really fixed as many games as the "vita"....................with the "vita", the best answer to higher resolution is still "sharpscale"..................

There's "Vulkan" drivers for the Raspberry pi4, and series of updates for other platforms that use emulators............largely from he cheaper price of smaller processor (cell phone processes) in the hardware. Some of that research and development, comes from taking a second look at the "32bit platform". (open-source also contributes to the updates, especially with ppsspp and adrenaline).

 

Instead of "real" select "integer"

I do not have my Vita handy but I bet that is what you looking for.

Since Vita's res is as double as PSP and you are using point instead of bilinear, it should just scale the little image you are getting to the whole display just as it is. Bilinear is the blurry one, point is the "jiggy" one. Hope it works, bud.

 

Thought this didn't work with PSP games for some reason but indeed it does.

For Shapscale on PSP/PS1, the "point" setting eliminates all bilinear filtering no matter what. The "bilinear" setting causes it to check the per-game flag in official settings and lets that control whether to use or not. So just set "point" if you don't ever want to deal with that blur in any PSP/PS1 game.

 

Problably nobody asked for my opinion, but I circumvented all these issues by running it on a ps vita TV and using the zoom feature of my TV. Problem solved , super happy.

 

Yeah, integer scaling is a great compromise for when native resolution isn't supported! Thanks for the advise.

 

Well I thought this is what we were aiming for. The main choices are blurred or pixelized, with the adrenaline filters offering a bunch of inbetween options. PSP and PS1 are low resolution, and even worse low-resolution 3D, and the Vita's large, sharp screen makes that very obvious.

For Adrenaline filters the "Advance AA" with smoothing off can be interesting, sort of a limited sharpening effect, though results will sometimes be weird.

There is the ge_patch project, which attempts to run PSP games at Vita resolution. However compatibility is limited, and because it can only render with the PSP processors, games that it does work on tend to take huge framerate hits. But some games play fairly well with it and it can still be interesting to try out.
