Dolphin on the vita?

PowerVR Series5 also supports OpenGL ES 3.0, based on my sources

Killzone Mercenary supposedly  runs on Open GL ES 3.2 as well, but that is irrelevant.

My question isn't that Vita run Dolphin because, by making this thread I have already gotten closer to my goal. My main question is actually that is python better than plain C in terms of Dolphin?
I'm mainly done my GUI, tmy next step is actually implementing Dolphin.

Ehh... It can technically run dolphin. But it's just too slow to get anything remotely playable. Not going to be worth it, mark my words.

python is very nice.

from org.emu import DolphinEmu

It has a package for everything.

javascript imo

Surely both of those are a little slow, as they're interpreted/JITed at runtime instead of compiled to bytecode first. Visual Basic .NET is clearly the superior option.

If that is true isn't it implemented into dolphin?

Have you even compiled Dolphin once? Just start there, then make a litte change, whatever, even if it's just changing a word.

Why does it feel like this guy is trolling us?

Which one? I feel some of them are trolling, some of them are just stupid.

I wouldn't want that rep of trolling.

Though orginally, I thought I was going with software rendering for the port because I knew couldn't do play around too much the GPU but, strangely, I started development just in time for this discovery today ... 
Maybe the universe is on my side this time, this time.

EDIT: Vita itself can run OpenGL ES, but it also has its own API. Learning something new every single day, because if this machine has interchangeable API's, then I'm playing with a fuller deck than I had hoped for.

But still will never be able to get any playable speeds...
Can't imagine New Super Mario Bros. Wii being fun at 2-3FPS (if it even gets that close) and that probably is the easiest game to emulate.

I'm just going to repeat this: there is no 32-bit JIT anymore so you are going to need a 64-bit ARM processor which the VITA doesn't have.
The nVidia SHIELD device is the fastest ARM device available for Dolphin which has a 64-bit processor (nVidia Tegra X1) speed of 2.0GHz... 
the VITA has a 32-bit processor (cortex A9) at a max of 444MHz (or 0.4GHz).

A Geekbench 3 Benchmark score for the Cortex A9 processor running at 1.5GHz is 815 points (remember this is more than 3x the speed of the Vita so it would actually be closer to 271 points if it scales linearly) , for the nVidia Shield it is: 4318 points
do the math: The nVidia Shield is at least 15x as fast, yet it still struggles to run any game at an acceptable framerate...

Compare this to a much used Intel Desktop processor (i3 6100 3.7GHz) that runs Dolphin with acceptable framerates: 14432 points, which is almost 3x as fast as the nVidia Shield and thus at least 50x as fast as the Vita... 

These are all just synthetic, I know, but they do give a good comparison in relative speed.

TL;DR
Vita Geekbench 3 score: ~271 points (1 PS Vita) = 0.61 point per MHz
Shield Geekbench 3 score: ~4318 points (15 PS Vita's) = 2.16 points per MHz
i3 6100 Geekbench 3 score: ~14432 points (50 PS Vita's) = 3.90 points per MHz
