People who used the Vita's web browser extensively saw the black bar on the left start burning in in less than a year.
It's funny because this should theoretically be impossible, since black pixels on an OLED shouldn't be lit at all. And yet, for some reason, on the Vita, they are.

I just signed out of my PSN account. Haven't logged in since I installed this. I'd like to think that's enough.

I believe only the Genesis core is in the correct format right now. Wait a bit.
It has to do with the brightness setting. Basically if you are doing something with part of the screen blacked out you need to lower the brightness way down. If you do it'll be fine. If you leave it up high though there will be burn in after heavy usage for months and months.
The point is that brightness shouldn't have anything to do with it because black pixels on an OLED should be off entirely.

I don't think I've ever owned an oled device that had completely black blacks. IIRC both my s3 and oled vita would still emit light if you viewed them powered on in the dark (and thus, see the mura effect on both)

I think he's talking about the fact that individual pixels can be turned off in an OLED screen--it should be outputting no colors (i.e. It would be black to the user).

Thats not how OLED works. Anything "Black" that is displayed on screen on an OLED means the pixels are OFF. It means those pixels are not being used. They are "fresh"
What you see when you then try and display a white image on them, is near-new pixels that have a much higher illumination than the ones that are around them.
Imagine an OLED screen with a total, full white screen, with a black box in the middle. Leaving that on 24hours a day for 6 months. Then, when you try to display a full white screen (without said black box in the center) The ghosting/burn in of the black box will be there, because the pixels around the black box have been used (they are dimmer) and the pixels around the black box are "used" and slightly "burnt out" from being used.
Displaying black on an oled does not burn into a display. It is what is around the black that burns in.

I know. Doesn't that also mean that there shouldn't be any perceivable light coming from the display when you have a fully black screen being output?

Not sure on the difficulty of porting those, but taken the speed with which the ports are happening it might be as easy as simply compiling for vita's arm processor via the toolchain and some api tweaks.
Anyways got that error a lot in browser and then in just worked. Really wish I didn't have to work today and could just work on vita home-brew. There's a version of Conway's Game Of Life on vita already? damn the internet moves way to fast. ok back to work thanks for the break gaf.
I have - even my old Nexus S did, my 2013 Moto X did, and my Apple Watch also does. I can put an all-black picture on my Apple Watch and display it in the dark and it is pitch-perfect black. My Vita's the only OLED I've had that has this problem.
As the previous poster I quoted can attest, the Vita's OLED - for whatever reason - does not turn pixels completely off for perfectly black pixels. Maybe incorrect calibration/gamma is causing the display to think it should still be slightly lit? No idea, but an all-black screen on an OLED Vita in a dark room will slightly emit light. (You would also not see the "mura" effect people complain about on all-black screens if this wasn't the case.)
The rest of your post does make sense for OLED in general, but what people seem to be complaining about is not the rest of the display fading faster than the black bar areas, but the black bars burning in. I suppose people could just be misdiagnosing the issue, though.

Yeah, i totally understand the mura effect (i have an OLED vita myself), just commenting on the poster who thought that having "black" is burning into the OLED, when it is completely the opposite. It is the area "outside" black that is illuminated that is being "burnt into" the screen.
For example, neogaf. What would burn into the screen would be the backgrounds (white, grey) but what you would SEE when trying to display an all white screen would be things like the neogaf logo, and the blue bars going across the screen. Because white on OLED is caused by R/B/G pixels burning at MAXIMUM capacity. They are been HEAVILY used. Meanwhile, the blue bars and the neogaf logo do not use as many pixels to burn, so when the screen then is all white, you see the remains of logos/bars that dont get heavy pixel use
It is why, on phones with on screen navigation keys get burn in, the burn in happens where the "black" is. Any area with black or dark blue will look brighter than the areas on the screen that have been showing bright white/whiter images than darker images. It LOOKS like the black has burnt into the screen but it is actually the pixels that are getting used AROUND that black area that are burning in/dying. It just gives the impression that the black has burnt in because its the part that you can see immediately on a full, white bright screen.
The devices you're quoting aren't just OLED, they're AMOLED, the difference being AMOLED is capable of turning individual pixels off, while the other (PMOLED) can't. I always assumed Vita 1000 wasn't AMOLED because I haven't seen it called that anywhere, but maybe I'm wrong?
Also any OLED screens are going to be more prone to burn in because most organic compounds will degrade faster than the inorganic compounds used in other screens. It'll still be nothing compared to CRTs back in the day but nothing is really.
Hooray my degree finally came in handy, sorry for being off-topic.

The Vita has an AMOLED screen, too. Sony just doesn't use the AMOLED name because Samsung's loose use of the term could make people confuse it with Pentile displays.
I don't know what Guess Who is talking about. What is being described is physically impossible for an OLED display of either type. He should probably double check to make sure he doesn't actually own a Vita 2000.

sorry but discussing about what kind of screen has Vita is not a little bit OT ???
the discussion is interesting so someone could make a topic for it, what do you think ?

Have you ever used your vita in the dark, like at night? Try viewing a pure black image on an oled vita. It's easy to see the whole screen still throwing out light, like there's a backlight or something (which is odd since I thought oleds operate without a backlight). It's why one easily sees the mura stuff on dark backgrounds.
I agree though that all this oled discussion is out of topic now. Any new retroarch development?

So what you're saying is that playing games at 4:3 (with black borders) is no more risky than playing at any other resolution when it comes to burn-in?
Sorry to keep things a bit off-topic, but this is a very important subject and it directly involves the emulators we'll be using via this hack.

Any resolution you play in will result in burn in. If you have either:
1.Black surrounded by white whites/bright colours, the brights will burn in, and the area where the black was when you were playing game will be "brighter" than the area that you were playing in.
2.Logos in general, these burn in, because they are usually made up of all 3 colours burning (R/B/G)
As a sidenote, if you use less brightness, this will cause the pixels to burn at less intensity, and burn in will take longer to occur
ALL oled (amoled and oled) screens will have burn in. The easiest way to check where, is to put an entire white screen (purewhite) and you will see where. PSVITA is harder to tell, because most people dont use the browser (no static icons to remain in place for too long) and games arent played for long playthroughs with either bright white images or logos for longer than a few hours at a time.
Phones on the other hand...
EDIT
This is what you will see if you smash your vita screen with a bright game playing in 4.3: That space on the side, with the brighter white area, that is where a black bar (no pixels illuminated) was most of the time. You will see the black look similar on the vita, with a much wider space of course. This was just a small, black area for on screen navigation controls on a phone.
In saying that, Vita games will RARELY show/need to show a full white screen that will show the burn in, as games usually have a lot of colours and information on screen.When you go to the VITA browser, since webpages have full white backgrounds usually, you will notice it then.

You are thinking backwards... whats happening is that the bottom 90% is being lit all the time compared to the black bars up top. So the bottom 90% is burning in slowly and you can see it compared to the top when viewing a full screen white image (the bottom 90% will be dimmer since its burned in more compared to the top)
The reason for this is that on the OG Vita, the pixels never go full OFF like you would normally expect on an OLED screen. It is always running at a minimum (say 1% intensity for R+G+B) because Gray-White response is usually much faster compared to a complete Black-White response. Think of the pixels as tiny strobe lights that you flick on and off, it takes a bit of time for the strobe to go completely dim. To increase motion quality, the Vita has all the pixels fired up. IIRC, all OLED panels do this but to varying degrees. The OLED screen on a modern Galaxy S7 phone would be so imperceptibly dim at "Off" that it would look like its completely off, compared to the ancient OLED panel used in the OG Vita.

Well lets hope sony doesnt release a firmware updatr in thr next 10 hours till i get home lol.
Thanks
Ha, that's great! But still, if you're using emulators, they'll still show up in your Activity Log, so...
As for the PSP loader... fuck. yeah!
That would help the problem, but I don't think I've ever seen that on an emulator, besides as people said already the screenburn is kind of overstated since you'll only really notice it on a pure white screen.
That said I was thinking of buying a vita 2000 for the extra battery when emulating, but I guess this is a good reason too.
Not surprised. Is probably just a TN-V port and I'm still hoping that the end result will be playing PSP titles directly from the main dashboard, but this is a good start!
Yep. That looks like ARK, though, not TN-V.
Ah. I never know the difference, I only know one is slightly better suited to running PSP stuff. I think.
ARK is a custom loader that is very focused on running games.
TN-V is basically the PSP menu, everything included (you actually need to have a copy of the PSP firmware to use it!)
I personally prefer ARK, since it's much more straightforwar than TN-V, although the latter has its advantages... especially in the looks department.

The emulators are posted on their site and as they are ports from emulators already out, expect the compatibility they have four other systems.
Genesis from retroarch works best from what people have said. it hasn't even been officially released but a dev shared it, i don't really care about genesis though. https://twitter.com/frangar/status/759453895080960000
next is the GBA emulator and the SNES emulator (available in the showcase). they both have slowdown and garbled sound. for the GBA one, try to grab the nightly build as it's more optimized.
haven't heard much about the other emulators.
people are really anticipating the full release of retroarch since it will probably be better than current emulators.
people probably ignored your question because usually it's better to experiment with emulators by yourself and see how games you want to play run.

So wait...installing this means I can't ever update, which means I can never access the Vita store? I kinda want to run some PC Engine games on this, but not that badly.
If you have a PS3, you can download any Vita game on the PS3 and transfer it to the Vita through usb/wifi. Once a new Vita firmware is released, you need to connect the Vita to qcma first, disconnect, and then connect the Vita to the PS3.
That's just how things go. It's a game of cat and mouse: someone finds and exploit, Sony patches it, and so on and so forth. That's just how the scene works. Until someone finds a way to make this permanent, of course. A CFW would be able to solve this issue, but until then, it's take it or leave it.
Games? Sure. On the PSN Store there are plenty of PSP and PSX games.
If you mean ISOs, then no. Not yet. When it's released, you will know. And this has nothing to do with PS1 games...
Edit:
A simple PSASBR mod by Major Tom. First mod of a Vita game!
Yes, it's that. But the game is actually being modified.
