WiFi not emulated and not supported!!
We won't make a 3DS/2DS emulator.

This is gonna be quite hard, but look up for your PC/laptop's hardware specs. Download a program like Speccy to know details about your computer. And then search the Internet for the drivers for it. GPU/video card drivers give significant performance boost once installed, so prioritize downloading and installing it.

Is dynarec/jit enabled via using '--cpu-mode=1', yes?

I already tried changing 3d renderers, and even setting the frameskip 1 up to 3. But fps drops at between 42 to 48.

On a side note, the Windows port runs smooth using Wine.

EDIT:
Tried compiling from svn, runs smoothly on 60 fps, can have a few slight and short hiccups sometimes ( drops on 55 or 58 fps) but otherwise, runs pretty great.

Also, do keep in mind that the emulator is resource intensive on the CPU, so that might also be a factor.

Maybe, your ROMs are corrupted? Try getting them from another source, or re-dump them again properly if you have physical copies of the games.

Ah... I see, guess I got worried about these lines too much. Thank you for the answer.

About the performance issue, is there anyway I can fix or improve the speed at least on par with the Windows port?

I was following a guide about compiling the latest source of DeSmuME for Ubuntu, here: https://gist.github.com/chrisyco/1470676

And I've got questions concerning about what the guide meant by: "Read the output carefully. If anything says "no", check you've installed it, and installed the right one. Then try again."

I've got at least 4 lines that says no when I tried ./configure:

Exactly what does this mean?

I tried compiling it with no errors occurred, and I was able to run it using 'desmume --cpu-mode=1' on terminal, but I'm bothered by the following lines:

Failed to set format: Invalid argument
Microphone init failed.

I'm a bit of a newbie on Ubuntu and Linux and general, so please understand.

Also, the emulator runs kind of slow on Ubuntu, I tested Glory of Heracles, at the start it runs finely about 59 - 62 fps and drops around 42-48 fps on the world map and other cutscenes, I also tried using OpenGL as the render engine and put frameskip on 1, 2 and 3, but the fps still drops. It's not like that on the Windows port though.
