Dolphin, the GameCube and Wii emulator - Forums

I know Vulkan is an irrelevant topic when it comes to the vita, but I deeply believe dolphin isn't. The vita has DirectX 9 and OpenGL 3.3 support. What makes the Vita not a first grab for the emulator? It is merely capable handling dolphin as to an android device. No?

Wow.

DirectX is only on Windows and Xbox. The Vita absolutely does not have this. Also, the Vita also has OpenGLES 2.0 support, not full OpenGL 3.3! Dolphin's mininum OpenGLES version is 3.0.

Because it's really old and really weak? A brand new super powerful phone SoC can't run Dolphin well. What makes you think a six year old one would be powerful enough?

Oh my god I remember you lol

-vita specs anyone? I come with reason behind my claim. 


Someone 10 years back managed to run null DC on the PSP. this was apparently forgotten and lost. https://www.youtube.com/watch?v=xV3EuUmJIZA 

If that could be done, that same could be possible with the vita, no?

i believe the vita is more capable to at least emulate PS2 and Wii.

How exactly did you guys learn to compile c++ to ARM though?

I'd like to start writing and compiling code to unlock these long lost mysteries finally.

Maybe try listening to us who do know about these things?

EDIT: Ok, lets take a look at Geekbench. It doesn't have any Vita CPU benchmarks, but the iPhone 4S uses the Cortex A9 too, but with a different clockspeed. Let's use that to analyze how the Vita compares to the A57s in the Nvidia Shield Android TV.

iPhone 4S
single core: 286
multi core: 490

But the vita runs at 333mhz, and the iPhone 4S runs at 800mhz! So lets do some math to convert those numbers...

Vita
single core: 119
multi core: 408 (the vita has twice as many cores as the iphone, so 204x2)

Now lets compare this to the Nvidia Android Shield TV's A57s...

Nvidia Android Shield TV
single core: 1491
multi core: 4262

No contest!

But doesn't overclocking change everything? It's a 2 ghz CPU.

It overclocks to 444mhz.

It doesn't matter that Cortex A9s are capable of going to 2ghz. The Vita doesn't let itself run beyond 444mhz.

Hah. No.
The Vita's GPU can't physically handle Dolphin(or proper NGC GPU emulation at all). It doesn't support /tons/ of features Dolphin needs for the GPU emulation.
Also even if that wasn't the case, the CPU is pitiful. It brings the latest generation of ARM CPUs to its knees. A wimpy underclocked Cortex-A9 can't do anything.

I still can't see why the Vita can't emulate at least game cube then? It's well capable of emulating PS2. I mean it's done it. I'm just asking questions before I crack eggs to bake a cake of code.

So um, that's Sonicadvance1. The writer of the ARM Jit, and why Dolphin is able to work on ARM at all. He knows what Dolphin needs!
