Nds Emulator Running On N900

Just going to leave this right here....

NDS Emulator N900

If it's old news, don't abuse me.

 

[Mithrildor]

The source for the PC version is avaible. So it could be ported, it would be even better if the source of the n900 version was avaible.

 

[SomeGuy99]

Hmmm. How fast does it run on the actual hardware then?

 

[kingoddball]

The porter is using a slow pc.
My SDK feels much slower than my actual phone (I'm on a core2 Macbook).

I'm awaiting a working binary as well.

 

[SomeGuy99]

But is it using x86 assembly routines?

I tried the Linux version of Desume on my Pentium M 1.6 ghz laptop the other day. The only game that ran at a playable speed was the Table Hockey tech demo (which was actually quite fun with a mouse!).

 

[kingoddball]

I've had that exact thought.

/Scratchbox has toolchains for both and apparently compatability is the same for both setups.
I'd like to see how it runs on actual hardware, at least there is a good speed running on "N900" (kinda ).
All that would remain is tweaking to get some playability.

You have to also remember, even thought it's an X86, it's emulating N900 hardware.
/Scratchbox is also an EMULATOR.

Why do I have a feeling this is a severe understatement.

Hang on, just using firing up the Exophase Signal...

 

[kingoddball]

The SDK also emulates the N900 itself. It's not just running the game in a linux window.

It's a least "nearly" working on some ARM hardware.

But how do you arrange the screens?

But how do you arrange the screens?

I've been thinking about this, and the best way is to send the video and sound information over a wifi link to a machine which can render it properly. I think a Nintendo DS should work for this.

 

[kingoddball]

Look at the screen in the first post.
They are a low resolution.
Wifi and Sound may be too early to talk about.
Especially the wifi game link anyway.

@ SomeGuy - Low resolution is why there is a decent speed.
Lower the resolution helps speed and cpu load, too.

Yep, I did find this when running desume on my desktop. But even then, almost nothing was playable.

I don't personally get why increasing the screen size affects the performance. Can't they just use a 'cheap' pixel doubling routine?

 

[kingoddball]

Zoom would be easiest. A simple and dirty enlargement.
It's not creating a higher resolution, just zooming?

Higher reso creates more pixels for the cpu to render, higher graphics for gpu and so on.

I don't know all too much about anything to do with this, but still.

Um... your PC is already rendering the amount of pixels relative to your monitor.

Sound off, no frameskip. This is one of the least taxing DS games I've run on it, just so you know (Electroplankton Demo).

Free, actually. The screen can be given a 400x240 resolution with hardware doubling. I'm not sure how, though, it may not be setup properly in the current firmware.

 

[SomeGuy99]

Well, at least WarioWare might run? This is with sound and frameskip 0.

 

[MonkeyChops]

...Electroplankton Demo).

Electroplankton is #1!!

Lets not turn another NDS thread into a debate about screen orientation again, please. We prob have like 20 of those already.

This is exciting tho, I must say. It would be sweet to play all my nds games on the andora2ut4: . It looks like we are one step closer to that.

 

[Caine]

Yes, no more screen discussions please.

Though this is interesting and gives hope that some games might become playable, I wouldn't expect to much from this yet for the time being.

 

[SomeGuy99]

Frameskip 0, with sound.

Same.

This would be awesome if it ever gets developed for pandora...
I can just imagine playing the new pokemon games! :lol:
