What to try when dolphin libretro fails?

I used to be able to run dolphin on my windows 10 system for months until something happened. First all games were running in half speed. probably exactly 50% and constantly even though I have a GTX 1080 card. until they stopped launching. I think it was a "memory could not be read" error and a blank screen. I just blamed this on a half-year old windows installation getting scrambled. I later started using retroarch for all my emulation needs and the same error/blank appeared, as expected.

Months went by and finally yesterday I reinstalled my windows 10 (x64, new 16299 build, fresh from scratch on formatted drive) and I was sure dolphin (via latest retroarch, latest dolphin core fetched today) would work with the fresh windows installation but no I got the same blank screen with familiar error:

Quote:RetroArch: retroarch.exe - Application Error
The instruction at 0x00007FFEF6B8288F referenced memory at 0x0000000000000000.
The memory could not be read.
Click on OK to terminate the program.

This happens with every game I've tried. I used the latest nvidia drivers and also tried the latest beta drivers. I'm sure there are other things I could try but since nothing useful is displayed I am at a loss. I can't even access dolphin settings because I can't load a rom to get there. It's difficult to live without dolphin for so long :(

Some old threads say I should turn off extensions limit in nvidia control panel but I can't seem to find it, I guess they've changed it.

Does dolphin work if you use it on it's own?

Yes. It found my old settings too (from My Documents it seems).
Could this help resolve launching via retroarch?

I copied over the folder from My Documents to retroarch\system\user, overwriting defaults but it was no help.
I noticed I get the error message a second or two before the blank screen appears which I thought was weird.
I also tried deleting the cache.

we don't support libretro. You'll need to find support elsewhere.

I'm confused. I thought the same people make it and that libretro just another version of dolphin. Where then might I find help?

The libretro version of Dolphin is just another version of Dolphin, but it wasn't made by us.

In that case what do you think about the libretro version?

It has some major problems right now (which isn't totally unexpected, considering how new it is). What remains to be seen is if they'll keep improving it in the future or if it'll stagnate.
