The "skip buffered effects" (buffered off) option is a hack that tries to analyze the way the game is rendering and skip parts of it to render faster. On a weak device, this can give you a much-needed FPS boost. It's still a hack and not recommended.

Buffered rendering is the use case I recommend.

I know that Dissidia has ghosting, and it's the same ghosting that is actually present on the PSP. Some people don't like it, but it's simply an intentional effect used in the game. Have you compared these areas with an actual PSP's rendering? Can you upload some nearby save data so I can quickly look at these same areas? (I don't have final mix, though, only the original.... so the save might not work for me.)

I'm not sure about the mirror - that looks like a bug for sure. It'd be great if you wanted to use the GE debugger to identify what's going on there:
... github.com/hrydgard/ppsspp/wiki/How-to-find-a-graphic-issue-with-the-GE-debugger

It looks like a blending issue, but it could be a logic op issue or even alpha testing. I think we did fix a small bug related to a combination of those since v1.2.2, so you might try the latest git build (on the downloads page) in case it was already fixed.

Also, what graphics card are you using, and have you updated its drivers? We use features like "dual source blending" which aren't available on some very old cards. If you go to Settings -> Tools -> System information, look at the API version near the bottom. If it's < v3.3.0, then your card or drivers could definitely be the problem.

Also, if you're using Direct3D 9 instead of OpenGL, that generally has more bugs and issues, and supports less things (Direct3D 9 doesn't even support dual source blending properly), so it will usually look worse.

Thanks for your comprehensive reply. Very helpful.

I made a new game record to test the mirror on snow white scenario and with:
+buffered effects ON
+rendering resolution 1x/auto resize
+Lower resolution for effects(Safe)

I was using openGL, but as you deduced, the API version was under 3.3.0.

Anyhow, just adding [Lower resolution for effects(Safe)] in addition to the previous 2 settings that were on, SOLVED the mirror issue.

For the master yen sid castle ghosting, I did a side-by-side comparison with real PSP hardware, and some quick ghosting check from the beginning of the game( where there was some strong lights that produced some ghosting)PPSSPP had
+buffered effects ON
+rendering resolution 1x/auto resize
+Lower resolution for effects(Safe)
As you deduced, the real hardware has some ghosting there too. It even has the similar poor blending and all.
Anyhow just enabling [Lower resolution for effects(Safe)] in addition the the settings I had, made the scene look almost perfect, when comparing to real psp(the ghosting and bad blending is almost on the same level that the real psp uses[intentionally] on this scene), so I'd say this was solved too.

Also, I should note that WITHOUT enabling [Lower resolution for effects(Safe)], the ghosting here is like 20%-30% stronger(inaccurate).

Texture filtering linear and texture scaling 2x XBR could be added without creating artifacts or significant slowdown, so people can enjoy crisp graphics despite the 1x rendering resolution.

This was all tested on both 1.2.2 and ppsspp-v1.2.2-288-g9a11cfb-windows-amd64 "autobuild". Again, thanks for your comments.[as a side note, it may be my imagination, but in ppsspp-v1.2.2-288-g9a11cfb-windows-amd64 the mirror animation seemed a bit more fluid]
